## 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__search__get_server` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__search__discover_server` `mcp__search__get_index_stats` `mcp__search__get_server` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **info** The word "credentials" in `get_server` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credentials".

description: "...it started when we ran it ourselves (no credentials, on a schedule), how it is maintained (..."
```

- **warn** Annotations that disagree with the tool in `get_install_config` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "get_install_config" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "get_install_config" says "get": a word for reading.
```


## Changes things (1)

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

### `get_install_config`

- The name "get_install_config" says "get": a word for reading.
- The description's first verb is "generate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Generate a ready-to-paste configuration snippet for connecting a discovered MCP server to Claude Desktop or Cursor. MCP servers cannot auto-install — users must manually add configuration. This tool reduces that friction.
```

## Only reads (5)

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

### `discover_server`

- 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 the live .well-known/mcp discovery manifest from an indexed MCP server. Returns transport endpoints, capabilities, and auth requirements needed to connect. Only works for servers that support MCP discovery.
```

### `get_index_stats`

- The name "get_index_stats" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "crawl": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Get overall statistics about the MCP Rating index: total servers, top categories, and last crawl time.
```

### `get_server`

- The name "get_server" says "get": a word for reading.
- Tag private-data: The description's first sentence says "get" and "credential": it reads secrets.
- Tag untrusted-input: The description's first sentence says "get" and "issue": it reads issues, which other people can write.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Get what is known about one MCP server by slug: whether it started when we ran it ourselves (no credentials, on a schedule), how it is maintained (last release, last code push, open issues, archived or deprecated), how to run it (install command or hosted endpoint), the keys it declares, its tools with their parameters, and roughly how many tokens its tool definitions cost. Listings are informational — verify details before installing.
```

### `list_categories`

- The name "list_categories" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List all available MCP server categories with the count of servers in each.
```

### `search_servers`

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

Description, as the server wrote it:

```untrusted-server-text
Search the MCP Rating index of MCP servers. Returns matches for a query, optionally filtered by category and sorted by quality, stars, downloads, recency, or name, each marked with the outcome of our own start test when we have run one, and with its last release and last code push dates where we know them. Quality scores are algorithmic estimates.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__search__search_servers",
      "mcp__search__get_server",
      "mcp__search__list_categories",
      "mcp__search__get_index_stats",
      "mcp__search__discover_server"
    ],
    "ask": [
      "mcp__search__get_install_config"
    ],
    "deny": []
  }
}
```

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

- `mcp__search__get_server`: private-data, untrusted-input
- `mcp__search__get_index_stats`: untrusted-input
- `mcp__search__discover_server`: untrusted-input
