**9 tools: 1 change things and 8 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |

## 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__directory__get_install` `mcp__directory__get_skill` `mcp__directory__list_categories` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__directory__get_install` `mcp__directory__get_skill` |
| 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.

### `whats_new`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Servers added to the directory recently, best first, plus health changes. Defaults to the last 7 days.
```

## Only reads (8)

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

### `compare_servers`

- The name "compare_servers" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare two to five servers side by side by slug: trust signals, auth, hosting, transport, tools count, license.
```

### `get_install`

- The name "get_install" says "get": a word for reading.
- Tag private-data: The description's first sentence says "chat": it reads messages.
- Tag untrusted-input: The description's first sentence says "chat": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
The exact config or command to install one server in one client: Cursor, Claude Code, Claude Desktop, VS Code, Windsurf, ChatGPT, Codex, Gemini CLI, Grok Build, Grok Bot, or plain JSON. For Grok Bot the value is the message to send in its chat. Includes the config file path and a one-click deeplink when the client has one.
```

### `get_server`

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

Description, as the server wrote it:

```untrusted-server-text
Details for one server by slug: description, tools, auth, transport, health, packages, and links. include_readme adds the README (trimmed).
```

### `get_skill`

- The name "get_skill" says "get": a word for reading.
- Tag private-data: The description's first sentence says "chat": it reads messages.
- Tag untrusted-input: The description's first sentence says "chat": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
One skill by slug: what it does, where the SKILL.md lives, and the install command for Cursor, Claude Code, Codex and Grok Build, plus the chat message that installs it in Grok Bot. include_body adds the SKILL.md text (trimmed).
```

### `list_categories`

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

Description, as the server wrote it:

```untrusted-server-text
Directory categories with listing counts. Use a slug as the category filter in search_servers.
```

### `recommend_servers`

- The description's first verb is "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Describe what the user wants to do in plain words. Returns the best three servers, each with why it fits, auth, remote or local, health, and the install snippet for the client.
```

### `search_servers`

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

Description, as the server wrote it:

```untrusted-server-text
Find MCP servers by product name, publisher, or topic. Ranked by relevance (exact name, then publisher, then tags and description), official and verified first, duplicates merged. Returns compact cards with trust signals; call get_install next.
```

### `search_skills`

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

Description, as the server wrote it:

```untrusted-server-text
Find agent skills (SKILL.md packs for Claude Code, Cursor, Codex, Grok Build and Grok Bot) by name, publisher or topic. Call get_skill for the install command.
```

## 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__get_install",
      "mcp__directory__list_categories",
      "mcp__directory__compare_servers",
      "mcp__directory__recommend_servers",
      "mcp__directory__search_skills",
      "mcp__directory__get_skill"
    ],
    "ask": [
      "mcp__directory__whats_new"
    ],
    "deny": []
  }
}
```

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

- `mcp__directory__get_install`: private-data, untrusted-input
- `mcp__directory__list_categories`: private-data
- `mcp__directory__get_skill`: private-data, untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-11-05T03:18:13.636Z, unchanged since 2026-11-05T03:18:13.636Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `1` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://plugmcp.ai/mcp-server: tools/list returned 9 tools to an anonymous client, including whats_new (write)
```
