## 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__fonto-docs__search_fonto_docs` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__fonto-docs__get_fonto_page` `mcp__fonto-docs__list_pages` `mcp__fonto-docs__lookup_api` `mcp__fonto-docs__search_fonto_docs` |
| 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 (4)

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

### `get_fonto_page`

- The name "get_fonto_page" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "fetch" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Fetch the full content of a Fonto documentation page by its slug (the part of the URL after /latest/). Use search_fonto_docs or list_pages first to find the right slug.
```

### `list_pages`

- The name "list_pages" says "list": 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
Filter Fonto documentation pages by title, product, or ancestry keyword. Returns all matches without ranking — useful when you know the product area or part of the page title. For full-text relevance search use search_fonto_docs; for the complete catalog use the fonto://catalog resource.
```

### `lookup_api`

- The name "lookup_api" says "lookup": 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
Look up a Fonto API symbol by exact name (function, class, manager, type, or component — e.g. 'documentsManager', 'createIconWidget', 'CvkOptions') and return its full documentation page in one call. Accepts call syntax ('registerWidget()'), import paths ('fontoxml-families/src/createIconWidget'), and member access ('documentsManager.getNodeById', resolved to the owner's page). Matching is case-sensitive first, so 'DocumentsManager' (class) and 'documentsManager' (instance) resolve to different pages; other same-named pages are listed as alternatives. If no page has that name, returns search suggestions instead — use search_fonto_docs for concepts or partial names.
```

### `search_fonto_docs`

- The name "search_fonto_docs" says "search": a word for reading.
- Tag private-data: The name "search_fonto_docs" says "search" and "doc": it reads documents.
- 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
Search the Fonto XML documentation using full-text search. Returns results ranked by relevance with titles, descriptions, and slugs. Best for looking up a concept, API name, or feature by keyword.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `fonto-docs`:

```json
{
  "permissions": {
    "allow": [
      "mcp__fonto-docs__search_fonto_docs",
      "mcp__fonto-docs__get_fonto_page",
      "mcp__fonto-docs__lookup_api",
      "mcp__fonto-docs__list_pages"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__fonto-docs__search_fonto_docs`: private-data, untrusted-input
- `mcp__fonto-docs__get_fonto_page`: untrusted-input
- `mcp__fonto-docs__lookup_api`: untrusted-input
- `mcp__fonto-docs__list_pages`: untrusted-input
