## 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__defaultrank__get_category_ranking` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__defaultrank__check_package_freshness` `mcp__defaultrank__get_category_ranking` |
| 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.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_package_freshness`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- 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
Checks dependencies (an object of package name to version range, as in package.json) against the npm registry. Returns packages that are a major version or more behind npm's latest, deprecated packages, and the current major to use. Useful before installing packages from memory.
```

## Only reads (2)

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

### `get_category_ranking`

- The name "get_category_ranking" says "get": a word for reading.
- Tag private-data: The description's first sentence says "database": it reads databases.
- Tag untrusted-input: The description's first sentence says "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Ranks the tools AI models recommend first and the tools they actually install in AI-built apps, for one category: auth, database or email.
```

### `get_tool_pick_rate`

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

Description, as the server wrote it:

```untrusted-server-text
For a developer tool (product name or npm package, e.g. 'Clerk', 'next-auth', '@supabase/supabase-js'), returns how often 6 AI models recommend it first, mention it, and actually use it in apps they build, with its rank and main competitor. Covers auth, databases and email.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__defaultrank__get_tool_pick_rate",
      "mcp__defaultrank__get_category_ranking"
    ],
    "ask": [
      "mcp__defaultrank__check_package_freshness"
    ],
    "deny": []
  }
}
```

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

- `mcp__defaultrank__get_category_ranking`: private-data, untrusted-input
- `mcp__defaultrank__check_package_freshness`: untrusted-input
