## 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__catalog__compare_tools` `mcp__catalog__find_alternatives` `mcp__catalog__get_tool` `mcp__catalog__search_tools` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__catalog__check_tool_status` `mcp__catalog__compare_tools` `mcp__catalog__find_alternatives` `mcp__catalog__get_tool` `mcp__catalog__list_tools` `mcp__catalog__search_tools` |
| 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 (6)

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

### `check_tool_status`

- The name "check_tool_status" says "status": 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
Check whether an AI tool is still alive. Returns active, deceased, or acquired — with the date and cause if it shut down, and live alternatives if it did. Use this before recommending a tool to avoid suggesting one that no longer exists.
```

### `compare_tools`

- The name "compare_tools" says "compare": a word for reading.
- Tag private-data: The description's first sentence says "compare" and "directory": it reads files.
- 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
Compare two AI tools side by side by their directory slugs. Returns each tool’s profile (pricing, rating, editorial verdict, lifecycle) plus the editor’s head-to-head verdict and bottom line when one exists for the pair.
```

### `find_alternatives`

- The name "find_alternatives" says "find": a word for reading.
- Tag private-data: The description's first sentence says "find" and "directory": it reads files.
- 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
Find curated alternatives to a given AI tool by its directory slug. If the tool has shut down, returns live replacements. Good for "what should I use instead of X" questions.
```

### `get_tool`

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

Description, as the server wrote it:

```untrusted-server-text
Get the full profile of one AI tool by its directory slug: description, pricing, key features, editorial verdict and rating, the date it was last human-verified, lifecycle status, and the official site URL.
```

### `list_tools`

- The name "list_tools" 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
List the top-rated active AI tools in a category or for a job role, optionally filtered by pricing. Good for "what are the best AI tools for sales" or "free tools in <category>".
```

### `search_tools`

- The name "search_tools" says "search": a word for reading.
- Tag private-data: The description's first sentence says "search" and "directory": it reads files.
- 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 AI Tool Directory catalog (2,000+ AI tools) by keyword, use case, or category using hybrid semantic search. Returns ranked tools with slug, one-line description, pricing model, and rating. Use this to discover tools, then get_tool for full detail.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__catalog__search_tools",
      "mcp__catalog__get_tool",
      "mcp__catalog__check_tool_status",
      "mcp__catalog__find_alternatives",
      "mcp__catalog__compare_tools",
      "mcp__catalog__list_tools"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__catalog__search_tools`: private-data, untrusted-input
- `mcp__catalog__get_tool`: private-data, untrusted-input
- `mcp__catalog__check_tool_status`: untrusted-input
- `mcp__catalog__find_alternatives`: private-data, untrusted-input
- `mcp__catalog__compare_tools`: private-data, untrusted-input
- `mcp__catalog__list_tools`: untrusted-input
