Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.2.2
Disambiguation5/5
Each tool has a clear, distinct purpose. There is no overlap: annotation management (annotate, deprecate, forget), schema retrieval (get_schema, list_tables), querying (query), searching (search), relationship discovery (discover_relationships, get_relationships), drift detection (detect_drift), and knowledge sync (sync_knowledge) are all separate concerns.
Naming Consistency5/5
All tools follow the consistent pattern `db_<verb>_<noun>` using snake_case. The verbs are descriptive and indicate the action (e.g., annotate, query, list_tables). No mixing of conventions or vague names.
Tool Count5/5
With 12 tools, the server is well-scoped for a database knowledge management system. Each tool serves a necessary function in the lifecycle of schema understanding, annotation, querying, and maintenance. Not overloaded nor sparse.
Completeness4/5
The tool set covers the core workflow: connection listing, table discovery, schema retrieval, querying, annotation CRUD (annotate, deprecate, forget), relationship discovery, drift detection, and knowledge sync. Missing a direct tool to view all annotations in isolation, but schema retrieval and search provide access.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must fully disclose behavior. It states annotations survive sessions, are merged into future db_get_schema responses, and calls it the core of persistent memory. This effectively communicates the mutating and persistent nature. It doesn't discuss permissions or reversibility, but given the positive intent (annotating for better future queries), the transparency is adequate.
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 well-structured with a brief summary, contextual motivation, usage guidance, parameter list, and return type. Every sentence adds value, and the length is appropriate for the tool's complexity. There is no redundancy or filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite 9 parameters and no annotations or output schema, the description covers the tool's purpose, when to use it, parameter semantics, and return format. It also explains how it integrates with db_get_schema, providing sufficient context for an AI agent to use it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% coverage (no descriptions), so the description must compensate. The Args section provides clear semantic explanations for each parameter, including schema qualification for table, relationship between column and column-level fields, and the dict format for enum_values. This adds significant meaning beyond the raw schema.
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 persists semantic annotations for tables or columns, surviving across sessions. It distinguishes from siblings by positioning itself as the persistent memory mechanism that feeds into db_get_schema, a unique role not covered by other sibling tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly advises calling this tool after discovering semantic knowledge (enum meanings, column purposes, relationships). While it doesn't list when to avoid it or name alternatives, the context and sibling list imply when to use versus when to use other tools like db_get_schema or db_query.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries the burden. It discloses that descriptions come from the knowledge store (richer than raw schema) and that tables are only shown if known. No destructive behavior implied. Return format 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with clear purpose, behavioral notes, Args, and Returns. Every sentence adds value, no fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one optional parameter, no output schema), the description covers all essential aspects: purpose, prerequisites, return format, and parameter behavior. Complete for its complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Single optional parameter 'connection' is documented with default behavior ('Defaults to first defined'), adding useful meaning beyond the schema type and default.
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?
Description clearly states it lists all known tables for a connection, including descriptions and column counts. It distinguishes itself from siblings like db_get_schema (which fetches schema) and db_annotate (which annotates) by noting that tables appear only after those actions.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides context by explaining that tables appear only after being fetched or annotated, guiding the user on prerequisites. However, it does not explicitly state when to use or not use this tool versus alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses that queries run in an immediately-rolled-back transaction and that write statements are blocked both statically and at the transaction level. It also outlines the return structure (rows, row_count, connection, database, truncated). Since no annotations are provided, the description carries the full burden and does so well.
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 concise and well-structured: a single sentence stating the core purpose, followed by a brief note on transaction behavior and a recommendation to use a sibling tool, then a bullet-style summary of parameters and return value. No superfluous information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (3 parameters, no output schema), the description covers the main behavioral aspects (transaction, write blocking), parameter semantics, and return format. It could optionally mention error handling or performance implications, but overall it is sufficiently complete for an AI agent to invoke correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description provides comprehensive meaning for all three parameters: sql (SELECT-only), connection (defaults to first defined), and max_rows (default 500, lower for large tables). This goes far beyond the bare schema, which only supplies names and types.
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 executes a read-only SELECT query and returns rows as a list of dicts. It specifies that write statements are blocked, making the purpose unambiguous. Although not explicitly compared to siblings, the verb-resource combination ('Execute a read-only SELECT query') is specific and distinct.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description advises to call db_get_schema first if unfamiliar with the table structure, providing a clear alternative. It also implicitly limits usage to read-only queries (SELECT only) and mentions max_rows for large tables. However, it does not explicitly exclude other query types or describe when not to use the tool beyond the SELECT constraint.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses the output format (neighbor list and join paths) and the prerequisite step. As no annotations are provided, the description carries full burden; it lacks explicit mention of side effects or idempotency but is sufficient for understanding behavior.
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 well-structured with clear sections for Args and Returns. It is concise without unnecessary words, front-loading the primary purpose and then detailing parameters and output.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no annotations, the description is comprehensive: it explains the output structure, prerequisite, and each parameter fully. An agent can correctly invoke this tool based solely on the description.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description fully compensates by explaining all three parameters, their purposes, defaults, and even a recommended maximum depth for depth. This provides complete semantic understanding.
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's purpose: retrieving the foreign key relationship graph for a table up to a given depth. It distinguishes itself from sibling tools by explicitly requiring db_discover_relationships to have been run first.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear usage context: it explains depth levels and that the prerequisite tool must be run first. However, it does not explicitly state when not to use this tool or mention alternatives beyond the prerequisite.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, but description explains the deprecation flag is surfaced in db_get_schema and that operation is reversible. Lacks details on permissions or side effects, but sufficient for a soft-retire 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?
Well-structured with summary, usage guidelines, and argument list. Slightly wordy but each sentence adds value. No redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 5 parameters, no output schema, and no annotations, the description covers all inputs, explains return format, and mentions interaction with db_get_schema. Distinguishes from sibling db_forget.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5

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?
Description clearly states the tool soft-retires a table or column annotation, distinguishing it from db_forget which removes entirely. Specific verb+resource combination.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states when to use (table/column still exists, should not be relied on) and when not (use db_forget instead). Also mentions reversibility via undo=True.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses that passwords and usernames are not exposed, which is a key behavioral trait. However, does not explicitly state read-only nature or any side effects, though implied for a list operation. No annotations to contradict or supplement.
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
