## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS not yet verified: we couldn't determine whether a plaintext access path exists.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 63/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 561 tokens (~187/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

This tool returns chunks of text, names, and URLs for matching documents. If the returned chunks are not detailed enough to answer the user's question, use `get_documents` with the `parent` from this tool's output to retrieve the full document content.

Input parameters:

- `query` (string, required): Required. The raw query string provided by the user, such as "How to create a Cloud Storage bucket?".

Output parameters:

- `results` (array): The search results for the given query. Each Document in this list contains a snippet of content relevant to the search query. Use the DocumentChunk.name field of each result with get_documents to re…

### `answer_query` (~127 tokens)

Use answer_query to get a grounded answer to a query about Google developer products. This tool has limited quota. This tool will synthesize information from the corpus to generate an answer to the query. answer_query grounds answers using the same corpus as search_documents. 
This tool returns the generated answer_text and a list of document names (references) used to generate the answer. Use get_documents with the document names to fetch the entire document content if needed.

If you get a 429 out of quota error, use search_documents instead.

Input parameters:

- `query` (string, required): Required. The query to answer.

Output parameters:

- `answerText` (string): The answer to the query.
- `references` (array): Output only. The resource names of the documents used to generate the answer.

### `get_documents` (~145 tokens)

Use this tool to retrieve the full content of a single document or up to 20 documents in a single call. The document names should be obtained from the `parent` field of results from a call to the `search_documents` tool. Set the `names` parameter to a list of document names.

Input parameters:

- `names` (array, required): Required. The names of the documents to retrieve, as returned by search_documents. A maximum of 20 documents can be retrieved in one call. The documents are returned in the same order as the `names`…

Output parameters:

- `documents` (array): Documents requested.
