NotebookLM Retrieval MCP

by dillettante

NotebookLM Retrieval MCP

Connect your own NotebookLM account to Codex, Claude Code, Claude Desktop, ChatGPT, or Claude web. Five bounded tools retrieve notebooks, sources, complete source text, summaries, and grounded answers with actual citation-to-source mappings. No tools create, rename, upload, share, or delete notebooks or sources.

ask sends your question to Google, consumes NotebookLM quota, and continues the notebook's existing conversation. It is advertised as a non-idempotent tool with a chat-history side effect. "Readonly" in the package name refers to notebook/source management, not to an absence of all server-side changes.

This repository supplies installable software, not a shared hosted service. Every user authenticates their own NotebookLM account. Web clients need a reachable, self-hosted HTTPS endpoint and an OAuth authorization server. A GitHub URL or a localhost stdio command is not a web connector URL. Client account plans and organization controls may restrict custom connectors.

Install locally

Requires Python 3.11+ and uv. Use your terminal on macOS, Linux, or Windows (PowerShell).

git clone https://github.com/dillettante/notebooklm-readonly-mcp.git
cd notebooklm-readonly-mcp
uv sync --frozen --no-editable
uv run --frozen --no-editable playwright install chromium
uv run --frozen --no-editable notebooklm login
uv run --frozen --no-editable notebooklm auth check --test

The upstream login command can open its own browser. Run it yourself and choose your account. For an existing browser session, consult uv run --frozen --no-editable notebooklm login --help; cookie extraction may need the upstream optional rookie-cookies package. Never send your cookie file to another person.

Register this local server with your client; it starts on demand:

uv run --frozen --no-editable notebooklm-readonly-mcp

No API key, Docker, or paid API service is required for local MCP transport. A valid NotebookLM account, Google's usage limits, and your chosen AI client's own access requirements still apply. The package is installed from GitHub; no PyPI publication is claimed.

Returned source text and summaries are untrusted reference material, not instructions. NotebookLM indexing may itself omit material; "complete" means the complete indexed text returned by its API. For [7] use references[].citation_number == 7, never the seventh entry in list_sources.

Configuration and privacy

Default: local stdio and your upstream default NotebookLM profile. Optional local-only aliases, notebook allowlists, profile selection and timeouts are described in configuration. No account data, cookies, machine paths or personal notebook IDs ship with this repository. See security before running a remote server.

The project uses the unofficial notebooklm-py library and is not affiliated with Google, OpenAI or Anthropic. Google's internal APIs can change and authentication can expire. See troubleshooting.

TDQS

A3.6/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=false, idempotentHint=false, and openWorldHint=true, so the write/external profile is partly covered. The description adds genuinely new context: it appends to the notebook's chat history, consumes NotebookLM quota, and returns references with real citation numbers and source IDs.

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?

Three short sentences, front-loaded with the core action and each carrying distinct information (action, side effect, cost, output detail). 'Sends the question to Google' is mildly redundant with the opening sentence, but overall it is tight.

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?

An output schema exists, so return-value explanation is not needed, and the description covers the key behavioral facts an agent needs: quota consumption, chat-history mutation, and citation-bearing references. The main gap is that the 'notebook' parameter's expected form (ID vs name) is never clarified.

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%, with two required parameters ('notebook', 'question') documented nowhere. The description references sending 'the question' and the 'notebook's chat history' but gives no format, identifier type, or constraints, so it does not compensate for the coverage gap.

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?

States a specific verb (Ask) and resource (Google NotebookLM about its sources), plus the side effect of appending to chat history. This clearly separates it from siblings like source_fulltext (raw text retrieval) and notebook_summary (summarization).

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 when-to-use or when-not-to-use guidance, and no sibling is named as an alternative. The description implies it answers questions grounded in notebook sources, but an agent must infer when to pick this over source_fulltext or notebook_summary.

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

A3.6/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully covered. The description adds one genuine behavioral fact beyond them – results are filtered by account visibility and an optional allowlist – but says nothing about pagination, ordering, or result limits.

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?

A single front-loaded sentence with no filler, and the returned fields are named before the scoping qualifier. Slightly compressed wording around 'optional notebook allowlist' costs it a perfect mark.

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?

For a zero-parameter, read-only listing tool with an output schema and full annotation coverage, the description supplies the one thing structured data cannot: the visibility scope governing what comes back. Nothing an agent needs to call it correctly appears to be missing.

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 tool takes zero parameters, so the baseline is 4. The schema is empty and there is no parameter syntax the description could or should explain; the passing mention of an 'allowlist' refers to server-side configuration, not a call argument.

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?

States a specific verb (List) and resource (notebook IDs and titles) plus the visibility scope (server account, optional allowlist). It is clearly a listing tool, though it never differentiates itself from siblings like notebook_summary, which returns different data about the same resource.

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?

Usage is only implied: an agent can infer this is the tool for enumerating notebooks, and the visibility scoping hints at when results may be empty. There is no statement of when to prefer it over notebook_summary or ask, and no prerequisites or exclusions.

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

B3.4/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is fully covered. The description adds that the notebook may be given as an exact ID or a unique title match, which hints at ambiguity behavior, but it never states what happens when a title is non-unique (error vs. arbitrary pick) or whether results are paginated.

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 front-loaded sentence that states the resource, the returned fields, and the accepted input form with no filler. Nothing could be removed without losing information.

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?

An output schema exists so return values need not be spelled out, and the annotations cover the safety profile, making the definition minimally sufficient for a one-parameter read tool. It falls short on how the 'unique title match' behaves on ambiguity and on routing relative to sibling tools such as source_fulltext.

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?

Schema coverage is 0%, so the description carries the burden for the single 'notebook' parameter, and it does add real meaning: the value can be either an exact notebook ID or a unique title match. It stops short of describing the failure mode for ambiguous or missing titles, which is the main residual gap.

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 gives a specific verb and resource ('List source IDs, titles and URLs') scoped to a notebook, so an agent immediately knows the operation. It does not distinguish itself from siblings like source_fulltext or notebook_summary, but the purpose itself is unambiguous.

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?

There is no explicit when-to-use guidance and no mention of alternatives such as source_fulltext for content retrieval or list_notebooks for discovery. The clause 'in an exact notebook ID or a unique title match' describes the parameter rather than the usage context, leaving the agent to infer when this tool is appropriate.

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

TDQS

B3.4/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, covering the safety profile. The description adds a genuinely useful behavioral caveat about the content's provenance (AI-generated, not primary source), but says nothing about what happens if the summary has not been generated or how fresh it is.

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 dense sentence with zero filler; the core action is front-loaded and the provenance caveat follows immediately.

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?

An output schema exists, so return values need not be described, and the safety annotations are present. The main remaining gap is that the lone parameter's expected format is undocumented in both schema and description.

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?

There is one required parameter ('notebook') with 0% schema description coverage, and the description does not clarify whether it expects a notebook ID, title, or URL. It fails to compensate for the complete documentation gap.

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?

States a specific verb and resource ('Read ... notebook summary') and adds the qualifier that the content is AI-generated derived material rather than the original source, which distinguishes it from the source_fulltext sibling without naming it.

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 phrase 'derived content, not the original source' implies you should use this when a synthetic summary suffices rather than when you need original text, which is implied guidance toward source_fulltext. However, no alternative is named and no explicit when-not condition or prerequisite is stated.

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

TDQS

A3.6/5.0
Behavior4/5

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, openWorld), so the bar is lower. The description still adds real value not present in structured fields: the no-truncation guarantee and the security instruction to treat output as untrusted reference data, which guards against prompt injection. It omits practical traits like output size or cost on very large sources.

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, zero filler, with the core capability statement first and the safety caveat second. Appropriately sized for a simple two-parameter retrieval tool.

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?

An output schema exists, so return-value explanation is unnecessary, and annotations carry the safety profile; the untrusted-data warning covers the remaining behavioral risk. The only real gap is that the two required parameters are undocumented anywhere, which the description does not compensate for.

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% and neither of the two required parameters is explained anywhere. The description implies a source is identified by the call, but adds no meaning, format, or relationship guidance for `notebook` vs `source_id`, leaving the agent to guess how to address a source.

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?

Specific verb (Return) plus specific resource (the full indexed source text) with a distinguishing scope qualifier ("without truncation"). It is clearly separable from list_sources/notebook_summary/ask, though it does not name a sibling explicitly.

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?

"Without truncation" implies this is the path to take when complete text is needed rather than an excerpt, but that contrast is left to inference. No explicit when-to-use, when-not, or named alternative is given.

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

Scored across 5 tools

Disambiguation5/5

Each tool targets a distinct action-resource pair: list_notebooks vs list_sources operate on different entities, source_fulltext vs notebook_summary clearly separate raw source text from derived AI summaries, and ask is a uniquely generative operation. Descriptions explicitly clarify the raw-vs-derived distinction, leaving no real overlap.

Naming Consistency3/5

Names mix conventions: list_notebooks and list_sources follow verb_noun, but source_fulltext and notebook_summary are noun_noun, and ask is a bare verb. Still readable and inferable, but not a predictable pattern.

Tool Count5/5

Five focused tools are well-scoped for a read-only retrieval server, each earning its place without redundancy or filler.

Completeness4/5

The read-only retrieval surface covers notebook listing, source listing, full text, summaries, and Q&A, matching the server's stated retrieval purpose. Minor gaps exist (no cross-notebook source search or content-write operations), but agents can work around them within the read-only scope.
