**5 tools: 1 change things and 4 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 1 | ask |
| Only reads | read | 4 | allow |

## 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__agentrank__lookup` |
| 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.


## Changes things (1)

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

### `evaluate`

- The name "evaluate" says "evaluate": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Deep quality evaluation of a tool or MCP server. Returns score, signal breakdown, and specific red flags (abandoned, no license, single contributor, poor issue health). Use this BEFORE recommending or installing any tool to verify it is safe and well-maintained.
```

## Only reads (4)

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

### `alternatives`

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

Description, as the server wrote it:

```untrusted-server-text
Find alternatives to a specific tool. Searches for similar tools and compares their quality scores. Use this when a tool scores poorly and you want to suggest better options, or when a user asks "what else is like X?".
```

### `lookup`

- The name "lookup" says "lookup": a word for reading.
- Tag private-data: The description's first sentence says "repository": it reads repositories.

Description, as the server wrote it:

```untrusted-server-text
Check if a specific GitHub repository is in the AgentRank index. Use this whenever a user mentions a specific tool or you encounter a GitHub URL, to verify its quality before recommending it.
```

### `recommend`

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

Description, as the server wrote it:

```untrusted-server-text
Get quality-ranked recommendations for a use case. Returns the top tools/skills sorted by AgentRank score. Use this when a user needs a tool for a specific purpose (e.g. "I need a database MCP server", "what's good for web scraping?").
```

### `search`

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

Description, as the server wrote it:

```untrusted-server-text
Search AgentRank's index of MCP servers, agent tools, and AI skills. Use this BEFORE installing or recommending any tool to find the best options ranked by quality signals (maintenance, community health, adoption). Always prefer higher-scored results.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__agentrank__search",
      "mcp__agentrank__lookup",
      "mcp__agentrank__recommend",
      "mcp__agentrank__alternatives"
    ],
    "ask": [
      "mcp__agentrank__evaluate"
    ],
    "deny": []
  }
}
```

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

- `mcp__agentrank__lookup`: private-data

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:06:15.823Z, unchanged since 2026-10-22T15:06:15.823Z. 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://agentrank-ai.com/mcp: tools/list returned 5 tools to an anonymous client, including evaluate (write)
