Scored 2026-11-05.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 72/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 538 tokens (~179/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### `check_ai_crawler_readiness` (~101 tokens)

Check AI crawler readiness

Check whether AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Bytespider, CCBot) can read a website, and whether it has llms.txt, schema markup and server-rendered content. Returns a 0-100 score and the failed checks.

### `validate_llms_txt` (~148 tokens)

Validate llms.txt

Validate an llms.txt file. Pass a website URL to fetch and check its /llms.txt (or /llms-full.txt), or pass the llms.txt text itself. Returns a 0-100 score, valid true/false, and each check. Use it to check a site or to review text drafted for the user. If both are given, the url is used.

Input parameters:

- `content` (string): The llms.txt text to validate, up to 200,000 characters. Leave empty when passing url.

Check AI citations

Check whether ChatGPT, Perplexity and Gemini cite a domain when asked the given questions. Send 1 to 5 realistic buyer questions (each at least 5 characters). Returns, per AI, how many questions cited the domain. Each check calls paid AI APIs, so the limit is 5 checks per 30 minutes per IP.
