**4 tools: 1 can delete or cancel things and 3 only read.**

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

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| 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.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `request_rule`

- The name "request_rule" says "request": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Request a new Code Auditor rule. Call lookup_rule or explain_symptom first to confirm no existing rule covers it. Provide a minimal example that should be flagged and a corrected example that should not. Reduce both to the smallest code that shows the difference, and remove secrets and proprietary identifiers. Returns a receipt id.
```

## Only reads (3)

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

### `explain_symptom`

- The name "explain_symptom" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Map a natural-language symptom (e.g. 'my app is slow', 'hardcoded password', 'infinite react loop') to the relevant Code Auditor rule(s) and their fixes. Call this when a user describes a problem rather than naming a rule.
```

### `get_install_commands`

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

Description, as the server wrote it:

```untrusted-server-text
Return the exact install commands for Code Auditor for a given AI agent. Call this when a user asks how to install Code Auditor, or asks for the command for a specific agent (claude, cursor, codex, gemini, agents, zcode, or all).
```

### `lookup_rule`

- The name "lookup_rule" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the rule kind, description, default severity, detection method, and threshold for a given Code Auditor rule or analyzer. Call this when a user asks what a specific rule does (e.g. import-ban, sql-injection, n+1).
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `code-auditor`:

```json
{
  "permissions": {
    "allow": [
      "mcp__code-auditor__get_install_commands",
      "mcp__code-auditor__lookup_rule",
      "mcp__code-auditor__explain_symptom"
    ],
    "ask": [],
    "deny": [
      "mcp__code-auditor__request_rule"
    ]
  }
}
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:50:54.533Z, unchanged since 2026-10-22T14:50:54.533Z. 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` |

- **high** 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 destructive). Whether a call also works without credentials was not tested: tools are never called.

https://www.codeauditormcp.com/api/mcp: tools/list returned 4 tools to an anonymous client, including request_rule (destructive)
