## 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__directory__get_server` `mcp__directory__list_categories` `mcp__directory__list_topics` `mcp__directory__search_servers` |
| 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 (5)

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

### `get_dataset_info`

- The name "get_dataset_info" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Dataset metadata: entry counts, generation timestamp, source, and licensing terms for bulk or training use.
```

### `get_server`

- The name "get_server" says "get": a word for reading.
- Tag private-data: The description's first sentence says "get" and "directory": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Get the full directory entry for one MCP server by id ('owner--repo', e.g. 'microsoft--playwright-mcp'). Includes install hint, license, stars, category, and editorial fields. Any install_hint is a best-effort guess from the repository language, not a verified command: relay the install_hint_caveat with it rather than presenting it as ready to run.
```

### `list_categories`

- The name "list_categories" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "directory": it reads files.

Description, as the server wrote it:

```untrusted-server-text
List all directory categories with slugs, names, and active-server counts.
```

### `list_topics`

- The name "list_topics" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "directory": it reads files.

Description, as the server wrote it:

```untrusted-server-text
List the curated GitHub topics that have a directory page, with active-server counts. Topics are assigned by repository owners and imported verbatim, so the full dataset carries thousands of them; this returns only the curated subset. search_servers accepts any topic string, curated or not.
```

### `search_servers`

- The name "search_servers" says "search": a word for reading.
- Tag private-data: The description's first sentence says "search" and "directory": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Search the MCP server directory by keyword and/or filters. Keyword matches name, description, and GitHub topics. Returns active servers sorted by relevance then stars. Supply at least one of query, category, or topic — with no query, filters alone enumerate a whole category or topic by stars. Data refreshes nightly from the public GitHub API. Any install_hint is a best-effort guess from the repository language, not a verified command: relay the install_hint_caveat with it rather than presenting it as ready to run.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__directory__search_servers",
      "mcp__directory__get_server",
      "mcp__directory__list_categories",
      "mcp__directory__list_topics",
      "mcp__directory__get_dataset_info"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__directory__search_servers`: private-data
- `mcp__directory__get_server`: private-data
- `mcp__directory__list_categories`: private-data
- `mcp__directory__list_topics`: private-data
