## Findings

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

```untrusted-server-text
The server marks "generate_robots" 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 "generate_robots" says "generate": a word for a change.
```


## Changes things (1)

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

### `generate_robots`

- The name "generate_robots" says "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
Build a robots.txt from per-category choices (allow, block or omit for training, dataset, search, user_fetch or other), optional per-token overrides, a default policy for other bots, paths, sitemaps and custom rules. Returns the file text, a per-crawler summary and notes. Read-only: it only returns text and changes nothing. Same engine as POST /api/generate.
```

## Only reads (3)

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

### `check_site`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch a site's /robots.txt (http/https on the default port only; private, loopback and internal addresses are refused; up to 512,000 bytes; results cached for 5 minutes) and report, for one path, which registry AI crawlers are allowed or blocked, plus validation errors and warnings. Read-only: one GET of /robots.txt with a RobotsGate user-agent. Same engine as GET /api/check.
```

### `list_crawlers`

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

Description, as the server wrote it:

```untrusted-server-text
Return RobotsGate's AI crawler registry: each crawler's robots.txt token, operator, category (training, dataset, search, user_fetch or other), whether the operator says it respects robots.txt, and a link to the operator's documentation, plus unverified entries and notes. Read-only, no network access. Same data as GET /api/crawlers.
```

### `validate_robots`

- The name "validate_robots" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Validate robots.txt text against RFC 9309 and report errors, warnings and, for one URL path, which registry AI crawlers are allowed or blocked and by which rule. Read-only, no network access. Same engine as POST /api/validate. Up to 50,000 characters over MCP (the whole JSON-RPC request must also fit in 64 KB); for larger files use POST /api/validate or check_site.
```

## Claude Code permissions

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

```json

  "permissions": {
    "allow": [
      "mcp__robotsgate__list_crawlers",
      "mcp__robotsgate__validate_robots",
      "mcp__robotsgate__check_site"
    ],
    "ask": [
      "mcp__robotsgate__generate_robots"
    ],
    "deny": []
