## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__developerknowledge__get_documents` `mcp__developerknowledge__search_documents` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `answer_query`

- The name "answer_query" says "query": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use answer_query to get a grounded, synthesized conceptual answer to a high-level question about Google developer products. For exact code samples, CLI flags, specific error messages, or full document walkthroughs, prefer `search_documents` followed by `get_documents` instead. 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. Always cite the authoritative source document names from `references` (`documents/...`) in your final response to the user. Use `get_documents` with the document names from `references` to fetch the entire document content if needed.

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

```

### `get_documents`

- The name "get_documents" says "get": a word for reading.
- Tag private-data: The name "get_documents" says "get" and "document": it reads documents. The description's first sentence says "retrieve" and "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
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 either the `parent` field of results from a call to the `search_documents` tool or the `references` field returned by the `answer_query` tool. Set the `names` parameter to a list of document names (`documents/...`), and cite the authoritative source documents used in your final response.
```

### `search_documents`

- The name "search_documents" says "search": a word for reading.
- Tag private-data: The name "search_documents" says "search" and "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
Use this tool to find documentation about Google developer products. The documents contain official APIs, code snippets, release notes, best practices, guides, debugging info, and more. It covers the following products and domains:


* ADK: adk.dev

* Android: developer.android.com

* Apigee: docs.apigee.com

* Chrome: developer.chrome.com

* Dart: dart.dev

* Firebase: firebase.google.com

* Flutter: docs.flutter.dev

* Fuchsia: fuchsia.dev

* Gemini CLI: geminicli.com

* Genkit: genkit.dev

* Go: go.dev

* Google AI: ai.google.dev

* Google Antigravity: antigravity.google

* Google Cloud: cloud.google.com & docs.cloud.google.com

* Google Developers, Ads, Search, Google Maps, Youtube: developers.google.com

* Google Home: developers.home.google.com

* Google Maps Platform: mapsplatform.google.com

* Google Workspace: knowledge.workspace.google.com

* TensorFlow: www.tensorflow.org

* Web: web.dev


This tool returns chunks of text, names, and URIs for matching documents. Prefer `search_documents` followed by `get_documents` when you need exact code samples, CLI flags, specific error messages, full tutorial walkthroughs, or deterministic keyword lookup. 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. When answering the user, always cite the authoritative source document resource names (`documents/...`) or URIs.

```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `developerknowledge`:

```json
{
  "permissions": {
    "allow": [
      "mcp__developerknowledge__search_documents",
      "mcp__developerknowledge__answer_query",
      "mcp__developerknowledge__get_documents"
    ],
    "ask": [],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__developerknowledge__search_documents`: private-data
- `mcp__developerknowledge__get_documents`: private-data
