## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__guidance__get_guidance` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__guidance__check_source_freshness` `mcp__guidance__get_guidance` |
| 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.

### `check_source_freshness`

- The description's first verb is "fetch": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Fetch one allowlisted official documentation page from the curated registry and compare its normalized text with the verified snapshot. Status is unchanged, updated, unavailable (could not be checked now) or unknown (no snapshot). Results are shared by all callers and cached for up to 15 minutes (1 minute when unavailable); live.cached and checked_at show when the page was actually fetched. When the per-source fetch limit is reached, status is unavailable with reason rate_limited. Publication and update dates are never inferred and are always null. Only registry source ids are accepted; no other URL can be requested.
```

### `get_guidance`

- The name "get_guidance" says "get": a word for reading.
- Tag private-data: The description's first sentence says "return" and "commit": it reads repositories.
- Tag untrusted-input: The description's first sentence says "return" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Return one curated record by its stable id (from search_guidance): provider, canonical source URL, applicability, limitations, labels, the date the source was verified, its snapshot hash and the ledger commit. Unknown ids return an error; nothing is fetched from the web.
```

### `search_guidance`

- The name "search_guidance" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List curated guidance records that match a target coding agent, model family, scope and topic. Returns official model guidance, platform documentation and Agent Skills standard records with labels, applicability and the date each source was verified. PromptingCraft.com methodology records are returned only when kind is promptingcraft_methodology and are never official provider guidance. Inputs are fixed categories only. Use get_guidance for the full record.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__guidance__search_guidance",
      "mcp__guidance__get_guidance",
      "mcp__guidance__check_source_freshness"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__guidance__get_guidance`: private-data, untrusted-input
- `mcp__guidance__check_source_freshness`: untrusted-input
