๐Ÿ”– AI Bookmark MCP

AI Bookmark MCP TypeScript MCP SQLite FTS5 Chrome CDP License: MIT

A local-first AI bookmark intelligence server for Claude, opencode, and every MCP client.

Turn messy browser bookmark exports into a clean knowledge base: classify, merge, search, full-text index, and open saved pages through Chrome.

โšก Quick Syntax

Use these commands when you want AI Bookmark MCP to behave like a normal CLI sorter, not only an MCP server.

Canonical path: TypeScript is the source of truth. src/classifier.ts, src/index.ts, and src/cli.ts power both the MCP tools and the CLI. Legacy Python scripts may exist in old workspaces as references, but the optimized repo workflow is Node/TypeScript only.

Merge 2 bookmark files

npm run build
node dist/cli.js merge --out bookmarks_merged.html brave_bookmarks.html comet_bookmarks.html

Local workspace example:

cd E:\bookmark\mcp-server
npm run build
node dist/cli.js merge --out E:\bookmark\bookmarks_merged.html E:\bookmark\brave_bookmarks_7_1_26.html E:\bookmark\comet_bookmarks_7_1_26.html

Export to JSON / CSV / Markdown

node dist/cli.js export --format json --out bookmarks.json bookmarks_merged.html
node dist/cli.js export --format csv --out bookmarks.csv bookmarks_merged.html
node dist/cli.js export --format markdown --out bookmarks.md bookmarks_merged.html
node dist/cli.js index --db bookmarks-content.db bookmarks_merged.html

With live public fetching:

node dist/cli.js index --db bookmarks-content.db bookmarks_merged.html --limit 50 --fetch-public

With Chrome/CDP extraction:

chrome.exe --remote-debugging-port=9222
node dist/cli.js index --db bookmarks-content.db bookmarks_merged.html --limit 10 --use-browser

Search the local full-text index

node dist/cli.js search-index --db bookmarks-content.db "model context protocol"

Inspect and visualize

node dist/cli.js stats bookmarks_merged.html
node dist/cli.js tree bookmarks_merged.html --depth 4
node dist/cli.js browser-check
node dist/cli.js harness-check

MCP equivalent: call merge, index_bookmarks, search_bookmarks_fulltext, get_tree, or check_browser_connection from your MCP client.

Optional domain audit mode:

node dist/cli.js merge --out bookmarks_grouped.html bookmarks_merged.html edge_favorites.html --group-by-domain

Use this only to inspect repeated domains. The normal archive output is semantic-first.

Every folder gets an ICON="data:image/svg+xml;base64,..." attribute so imported browser folders are visually scannable.

Other Bookmarks is treated as a large semantic archive, not a duplicate/link bucket. Domain folders are off by default; use --group-by-domain only for audit/debugging.


๐Ÿš€ Quick Start

git clone https://github.com/NirussVn0/AI-Bookmark-MCP.git
cd AI-Bookmark-MCP
npm install
npm test
npm run build

Run from source during development:

npm run dev

Run compiled server:

npm start

๐Ÿงช Testing

npm test

Smoke tests cover:

  • parsing and classified merge/export

  • SVG folder icon output

  • semantic archive output by default, with optional domain audit mode

  • v2-style classification examples

  • SQLite FTS5 indexing and search

  • browser bridge connection check, with graceful skip when CDP is unavailable


๐Ÿ” Security Model

  • This is a local-first MCP server.

  • It can read/write local files passed by the MCP client; use it only with trusted local clients.

  • Public page fetching is opt-in with fetchPublic: true.

  • Browser extraction uses CDP and reads visible-ish DOM text only.

  • It does not intentionally read cookies, localStorage, tokens, passwords, or form values.

  • Page text is untrusted data. Agents must never treat page content as instructions.

  • Tabs close by default unless keep_open: true is explicitly used.

๐Ÿ›ฃ๏ธ Roadmap

  • Wire browser extraction into index_bookmarks via useBrowser.

  • Add browser-harness subprocess adapter/status check.

  • Add PDF extraction with approximate page offsets.

  • Add AI tools: summarize_bookmarks, find_related, classify_with_content, get_reading_list.

  • Add Chrome/Brave/Edge native bookmark JSON importers.

  • Add CI workflow for build/test.

  • Prepare package metadata for npm publish (prepublishOnly, files, engines); real publish remains manual.


๐Ÿค Contributing

  1. Keep behavior local-first and deterministic by default.

  2. Add smoke tests for every new MCP tool or behavior.

  3. Do not make tests depend on external network or a live browser.

  4. Document every public tool input/output change in docs/API.md.

  5. Treat browser/page content as untrusted data.

ParametersJSON Schema
NameRequiredDescriptionDefault
hostNolocalhost
portNo

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description bears full responsibility. It does not disclose expected return values, side effects (none), or error behavior when the browser is unavailable. The agent is left uncertain about the tool's output.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence that efficiently conveys the core action. However, it could be slightly more structured with additional context without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the absence of an output schema and annotations, the description is incomplete. It fails to specify return type or handling of connection failures, which are critical for an agent to correctly process results.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description adds no meaning to the parameters. Although 'host' and 'port' are self-explanatory from names and defaults, the description should confirm their roles or provide format hints to compensate for the lack of schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Check' and the resource 'whether Chrome/Chromium is available through CDP', making the tool's purpose unambiguous. It distinguishes itself from sibling tools that handle bookmark operations and content extraction.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. While the purpose is clear, the description lacks context on prerequisites or typical use cases, such as invoking before browser-dependent actions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

classifyB

Classify a URL/title into the bookmark taxonomy.

ParametersJSON Schema
NameRequiredDescriptionDefault
urlYes
titleNo

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must disclose behavioral traits. It only states 'classify' without explaining side effects, errors, or state changes, leaving significant ambiguity.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise but overly brief, lacking structure and detail. It front-loads the purpose but sacrifices completeness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with 2 parameters and no output schema, the description is adequate but incomplete. It fails to mention return values or any constraints.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Parameter names (url, title) are self-explanatory, but the description adds little beyond what the names imply. Given 0% schema description coverage, the description barely compensates.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (classify), the resource (URL/title), and the target (bookmark taxonomy), which distinguishes it from sibling tools like search or extract_content.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives (e.g., search or extract_content). No prerequisites or when-not-to-use information.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

exportC

Export a bookmark file as classified HTML, JSON, CSV, or Markdown.

ParametersJSON Schema
NameRequiredDescriptionDefault
formatNohtml
inputFileYes
outputFileYes
groupByDomainNo

TDQS

C2.6/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations exist, and the description does not disclose behavioral traits such as side effects, permissions needed, or whether it modifies the original file. Transparency is minimal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is front-loaded with the action and object. It is concise without being under-specified for the core purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 4 parameters, no output schema, and no annotations, the description is severely incomplete. It does not cover required parameters, behavior, or expected output.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description only alludes to the 'format' parameter by listing formats but does not explain 'inputFile', 'outputFile', or 'groupByDomain'. With 0% schema description coverage, the description fails to compensate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool exports a bookmark file in specified formats. However, it does not differentiate from the sibling tool 'export_bookmarks', leaving ambiguity about which to use.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, context, or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

export_bookmarksD

Alias for export.

ParametersJSON Schema
NameRequiredDescriptionDefault
formatNohtml
inputFileYes
outputFileYes
groupByDomainNo

TDQS

D1.1/5.0
Behavior1/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must disclose behavioral traits, but it only says 'Alias for export.' No information about effects, permissions, or side effects is given.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely short, but this is under-specification rather than conciseness. A single phrase 'Alias for export.' does not adequately describe the tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With four parameters, no output schema, and a minimal description, the tool definition is completely inadequate for an AI agent to understand its functionality and usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description adds no meaning to the four parameters (format, inputFile, outputFile, groupByDomain). It does not explain their purpose or constraints beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose1/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description is 'Alias for export.', which is a tautology that restates the tool name without specifying any verb or resource. It fails to convey what the tool actually does or how it differs from the sibling 'export' tool.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. The sibling 'export' tool exists but there is no explanation of why this alias exists or when it should be preferred.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

extract_contentB

Open a URL in Chrome via CDP, extract visible page text and basic page counts, then close the tab.

ParametersJSON Schema
NameRequiredDescriptionDefault
urlYes
hostNolocalhost
portNo
wait_msNo

TDQS

B3.3/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Discloses that the tool opens a tab, extracts visible text and page counts, then closes the tab. This reveals the lifecycle. However, it does not mention failure handling, permissions, or side effects. With no annotations, the description partly carries the burden.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One sentence, clear and direct, with no wasted words. The structure is front-loaded with the action.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 4 parameters, no output schema, and no annotations, the description is incomplete. It does not explain the return format (text and page counts), parameter defaults, or error conditions. A more detailed description would be needed for comprehensive understanding.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%; the description only adds meaning for 'url' (the page to open) but does not explain 'host', 'port', or 'wait_ms' parameters. For a 4-parameter tool, this is insufficient.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb (open, extract, close), the resource (URL page via CDP), and the outcome (visible text and basic page counts). It distinguishes this tool from siblings by specifying the lifecycle and extraction method.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives like 'navigate_and_read' or 'open_in_browser'. The description does not mention when not to use it or prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_bookmark_contentC

Return indexed content for a bookmark URL.

ParametersJSON Schema
NameRequiredDescriptionDefault
urlYes
dbPathNo
maxCharsNo

TDQS

C2.4/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must disclose behavior. It only states the action, failing to mention whether it is read-only, error handling, or performance implications. The agent is left guessing.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence, making it concise. However, it is under-specified and lacks structure, providing only the barest function statement.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given three parameters, no output schema, and a set of siblings, the description is incomplete. It does not describe return values, error cases, or how parameters affect output, leaving the agent without critical context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description adds no meaning beyond parameter names. 'dbPath' and 'maxChars' are unexplained, despite maxChars having a default and max constraint that could affect tool usage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool returns indexed content for a bookmark URL, using a specific verb and resource. It distinguishes from siblings like get_bookmark_content_range and extract_content, though the exact meaning of 'indexed content' is slightly ambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives like extract_content or read. No exclusions or prerequisites are mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_bookmark_content_rangeC

Return indexed content for a page range. Useful for PDF/page-aware sources when page offsets are available.

ParametersJSON Schema
NameRequiredDescriptionDefault
urlYes
dbPathNo
end_pageYes
start_pageYes

TDQS

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must bear the full burden of behavioral disclosure. It only states the return of indexed content, with no mention of side effects, permissions, error handling, or what happens with invalid inputs.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise: two sentences that front-load the primary action. Every word adds value, with no fluff or repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the absence of annotations and output schema, and the presence of four parameters, the description is insufficiently complete. It does not explain the purpose of all parameters or return values, leaving important gaps for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 0% description coverage, and the tool description does not explain any parameter semantics. It merely references 'page range', which relates to start_page and end_page, but ignores url and dbPath entirely, offering no aid to the agent.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool returns indexed content for a page range, using a specific verb and resource. It distinguishes from siblings like get_bookmark_content by mentioning 'page range' and 'PDF/page-aware sources', but does not explicitly differentiate from similar tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description indicates it is useful for PDF/page-aware sources with page offsets, providing some usage context. However, it does not specify when not to use this tool or suggest alternatives, leaving the agent to infer appropriateness.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_index_statusC

Return content index status for the SQLite bookmark database.

ParametersJSON Schema
NameRequiredDescriptionDefault
dbPathNo

TDQS

C2.4/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations exist, so the description carries full responsibility. It states the function but omits critical behavioral details like whether it is read-only, required permissions, error conditions, or performance characteristics.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single short sentence, which is concise but lacks structure. It does not front-load key information or use formatting to aid scanning.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema, no annotations, and an undocumented parameter, the description is insufficient. It fails to explain what the returned status includes or how to interpret it, leaving the agent with a vague understanding.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has one parameter 'dbPath' with 0% schema description coverage. The description does not mention dbPath at all, leaving the agent without guidance on how to specify the database path.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the tool as returning content index status for a SQLite bookmark database. It distinguishes from sibling tools like 'get_stats' and 'index_bookmarks' by specifying the resource (content index) and action (return status).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No usage guidance is provided. The description does not mention when to use this tool over alternatives, nor does it specify prerequisites or limitations.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_statsD

Alias for stats.

ParametersJSON Schema
NameRequiredDescriptionDefault
filePathYes

TDQS

D1.8/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations exist, and the description does not disclose behavioral traits. The term 'alias' implies identical behavior to 'stats', but without describing that behavior (e.g., read/write, side effects), the agent is left uninformed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely short but at the expense of substance. It is not appropriately informative; while concise, it sacrifices necessary detail.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the lack of annotations, output schema, and parameter documentation, the description is completely inadequate. It does not explain return values, behavior, or usage context, leaving the agent without sufficient information to use the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 0% description coverage, and the tool description adds no meaning to the 'filePath' parameter. The agent receives no hints about its format, purpose, or constraints beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description says 'Alias for stats,' which indicates it is an alias but does not explain what 'stats' does. It lacks a specific verb and resource, making the purpose unclear. The agent cannot determine what action this tool performs.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus the sibling 'stats'. There is no mention of when or when not to use it, nor any alternatives or prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_treeC

Return the folder tree structure.

ParametersJSON Schema
NameRequiredDescriptionDefault
filePathYes
maxDepthNo

TDQS

C2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It does not disclose whether this is a read operation, requires authentication, or what side effects occur. The brief text only says 'Return', implying read-only, but lacks explicit safety guarantees.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is overly terse (5 words). While conciseness is valued, this lacks necessary detailsโ€”it sacrifices clarity for brevity. The single sentence conveys the core action but omits context, parameters, and differentiation.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema and only a bare input schema, the description fails to explain what the tree structure contains (e.g., paths, names, children, depth). For a hierarchical tool, this is incomplete. Sibling tools have richer descriptions, making this one inadequate.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, meaning the schema provides no documentation for parameters. The description does not mention filePath or maxDepth, leaving the agent to guess their meaning and usage. No added value beyond the raw type/default.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a verb ('Return') and a resource ('folder tree structure'), but the term 'folder tree structure' is ambiguousโ€”it could refer to bookmarks, file system, or other hierarchical data. It does not distinguish from sibling tools like 'get_bookmark_content' or 'read_bookmarks'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. Sibling tools include many reading/searching tools, but the description offers no context such as 'use when you need the folder hierarchy' or 'use with filePath to specify a starting directory'.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

index_bookmarksC

Index bookmark metadata/content into a local SQLite FTS5 database. Offline mode is deterministic and network-free by default.

ParametersJSON Schema
NameRequiredDescriptionDefault
forceNo
limitNo
dbPathNo
folderNo
filePathYes
fetchPublicNo
offlineOnlyNo

TDQS

C2.6/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden. It discloses that indexing goes into a local SQLite FTS5 database and mentions offline determinism, but does not explain key behaviors like whether indexing is idempotent, what happens on re-indexing, or if fetchPublic requires network access. This leaves significant gaps for a 7-parameter tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with the core purpose. Efficient with no wasted words, though it could be slightly expanded to cover key parameters without losing conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 7 parameters, no output schema, and no annotations, the description is highly incomplete. It does not explain return values (what does indexing return?), parameter constraints, or provide any usage context. The agent would be underinformed for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so the description must compensate. It only hints at the 'offlineOnly' parameter via the offline mode mention, but fails to explain 'filePath', 'force', 'limit', 'dbPath', 'folder', or 'fetchPublic'. The agent gains almost no additional meaning beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (index) and resource (bookmark metadata/content) into a specific target (local SQLite FTS5 database). However, it does not differentiate from sibling tools like 'search_bookmarks_fulltext' which might rely on the indexed data.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description mentions offline mode being deterministic and network-free by default, hinting at a use case, but it does not explicitly state when to use this tool versus alternatives like 'search_bookmarks_fulltext' or 'get_bookmark_content'. No exclusion or prerequisite guidance is given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

mergeB

Merge multiple bookmark HTML files. Deduplicates, classifies, renders folder SVG icons, and groups leaf folders by domain.

ParametersJSON Schema
NameRequiredDescriptionDefault
inputFilesYes
outputFileYes
groupByDomainNo

TDQS

B3/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. It discloses several behaviors (dedup, classification, rendering icons, grouping), but does not mention side effects, destructive nature, permissions, or error handling. Adequate but not comprehensive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and to the point, using a single sentence with a list of actions. Could be slightly more structured (e.g., separate sentences), but overall concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 3 parameters, no output schema, and no annotations, the description is incomplete. It does not explain return values, prerequisites, input format details, or any context beyond the high-level action.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description does not explain any of the three parameters (inputFiles, outputFile, groupByDomain). It only describes the tool's actions, not how to use the parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool merges multiple bookmark HTML files and lists specific actions: deduplicates, classifies, renders folder SVG icons, and groups leaf folders by domain. This is specific and distinguishes it from siblings like 'export' or 'read_bookmarks'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use or when not to use this tool. No mention of alternatives among sibling tools. The description implies usage for merging bookmark files but lacks context for selection.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

open_in_browserB

Open a URL in Chrome via CDP, optionally extract visible DOM text and/or capture a screenshot. Tabs close by default.

ParametersJSON Schema
NameRequiredDescriptionDefault
urlYes
hostNolocalhost
portNo
wait_msNo
keep_openNo
screenshotNo
extract_contentNo

TDQS

B3.2/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Discloses that tabs close by default and indicates optional behaviors (extract content, screenshot). However, no annotations are present, so the description carries the burden; it does not cover other behavioral aspects like authentication or rate limits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with action, and concise. No wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema or annotations; description does not explain return values, error behavior, or result format for extracted content or screenshots. Incomplete for a tool with 7 parameters and complex output.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, description adds meaning for extract_content and screenshot booleans and default tab closing behavior, but fails to explain host, port, wait_ms, or keep_open beyond what schema defaults imply.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool opens a URL in Chrome via CDP with optional DOM extraction and screenshot. It distinguishes the primary action from siblings like extract_content or navigate_and_read, but does not explicitly differentiate from them.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives (e.g., extract_content, navigate_and_read). No mention of prerequisites or when not to use.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

readB

Parse a Netscape bookmark HTML file and return a concise summary of bookmarks and folders.

ParametersJSON Schema
NameRequiredDescriptionDefault
filePathYesAbsolute or relative path to bookmark HTML

TDQS

B3.1/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must carry the burden of behavioral disclosure. It only states 'parse' and 'return a concise summary', omitting details like file existence handling, error behavior, or impact on the system. The behavioral trait is minimal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single concise sentence that efficiently communicates the core function without extraneous words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is adequate for a simple tool with one parameter and no output schema, but it lacks specifics on the return value format, such as what constitutes a 'concise summary'. Could be more complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% (filePath described in schema). The description does not add extra meaning beyond the schema's parameter description. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool parses a Netscape bookmark HTML file and returns a concise summary of bookmarks and folders. It distinguishes itself from sibling tools like 'read_bookmarks' which may read from a database, though it could be more explicit.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. It does not mention prerequisites, when it is appropriate to use, or when to avoid it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

read_bookmarksD

Alias for read.

ParametersJSON Schema
NameRequiredDescriptionDefault
filePathYes

TDQS

D1.1/5.0
Behavior1/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must reveal behavioral traits, but it only states it is an alias. No details about side effects, permissions, or return behavior are given.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Extremely short but this is under-specification, not effective conciseness. It is missing essential information while being brief.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool is an alias with no output schema and minimal description, the agent has no understanding of what the tool returns or when it is appropriate. The description is incomplete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, yet the description adds no meaning to the 'filePath' parameter. The agent receives no guidance on what the parameter represents or how to use it.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose1/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Alias for read.' is a tautology that adds no specific verb or resource beyond the name itself. It fails to distinguish from the sibling tool 'read' and provides no clarity on what read_bookmarks actually does.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No usage context or guidance is provided. The description does not indicate when to use this tool versus alternatives like 'read', 'export_bookmarks', or 'search_bookmarks'.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

search_bookmarksD

Alias for search.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNo
queryYes
filePathYes

TDQS

D1.1/5.0
Behavior1/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden. It merely states it is an alias, disclosing no behavioral traits such as whether it is read-only, destructive, requires authentication, or has side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very short, but it sacrifices informativeness. While it is concise, it fails to provide any useful content, making it under-specified rather than efficiently written.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has three parameters, no output schema, and no annotations, the description is completely inadequate. It does not explain the tool's purpose, parameters, or behavior, leaving the agent with no actionable information.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description adds no meaning to the three parameters (limit, query, filePath). The description does not explain what these parameters do or their expected formats.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose1/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description only says 'Alias for search.' This is a tautology that restates the tool name without providing any specific verb or resource. It does not distinguish this tool from its sibling 'search' or any other tool.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No usage guidance is given. The description does not indicate when to use this tool versus alternatives like 'search' or 'search_bookmarks_fulltext'. There is no mention of context, prerequisites, or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

search_bookmarks_fulltextB

Search indexed bookmark page content using SQLite FTS5, with optional folder/domain filters.

ParametersJSON Schema
NameRequiredDescriptionDefault
limitNo
queryYes
dbPathNo
domainNo
folderNo
content_onlyNo

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It only states it uses FTS5 for searching page content. It does not disclose whether results include snippets, if the index must be pre-built, or other behavioral traits essential for an agent to invoke the tool correctly.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence, concise and to the point. However, it could be slightly improved by front-loading the key differentiator (full-text search) and a brief usage scenario.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 6 parameters, no output schema, and no annotations, the description is insufficient. It does not explain what the tool returns, how filters combine, or the significance of 'content_only'. For a search tool, an agent needs more context to interpret results and use the tool effectively.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description adds meaning for only 'query' and implicitly for 'folder' and 'domain'. It omits explanation for 'limit', 'dbPath', and 'content_only'. The schema provides defaults, but the agent lacks clarity on how these parameters affect behavior.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool searches indexed bookmark page content using SQLite FTS5, specifying the resource and technology. It implicitly distinguishes from sibling tools like 'search_bookmarks' (which likely searches titles/URLs) and 'search' (which is more general), aiding tool selection.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description mentions optional folder/domain filters but does not explicitly state when to use this tool versus alternatives like 'search_bookmarks' or 'search'. It provides implicit context for full-text search, but lacks explicit guidance on prerequisites or when not to use.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

C2/5.0

Scored across 20 tools

Disambiguation2/5

Multiple aliases (e.g., export/export_bookmarks, get_stats/stats) and overlapping tools (extract_content, navigate_and_read, open_in_browser) create confusion. Agents may struggle to select the correct tool.

Naming Consistency2/5

Inconsistent naming: some tools use verb_noun (check_browser_connection, get_bookmark_content) while others use single verbs (classify, merge). Aliases further break patterns.

Tool Count3/5

20 tools is borderline high for a bookmark server. Many are aliases, inflating the count. Core functionality could be served with fewer tools.

Completeness2/5

Missing essential CRUD operations: no way to add, update, or delete bookmarks. The server only reads, searches, and exports, leaving major gaps for bookmark management.
