How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (get_report). See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability68
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 586 tokens (~195/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management67
- Stability observed for 20 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage97
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 90% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_report Paid AI visibility report (x402) ~303
Paid: the Lite report for 29 USDC (default) or the Full report for 49 USDC (tier "full"), via x402 (scheme exact). The same reports as the $29 Lite and $49 Full reports on the website. Returns the full report as JSON plus a private report link. Call once without `payment` to get the x402 payment requirements, then call again with the same arguments plus `payment` set to the base64 PAYMENT-SIGNATURE value. Payment is settled only if the report is delivered. If the call fails or times out after you pay, call get_report again with the same arguments and the same payment to get the result; you are never charged twice. If your x402 client caps payments, raise the cap to at least 49 USDC to buy the Full report.
| Name | Type | Req | Description |
|---|---|---|---|
| brand | string | – | Business name (default: derived from the domain) |
| category | string | – | – |
| competitors | array | – | Up to 5 competitor names |
| payment | string | – | x402 v2 PAYMENT-SIGNATURE header value (base64 JSON payment payload) |
| prompts | array | – | Your prompts are answered first. We add generated questions to fill the rest, up to 25. |
| tier | string | – | "lite" (default, 29 USDC) or "full" (49 USDC) |
| url | string | yes | Website URL, e.g. https://example.com |

get_scan_details Paid scan details (x402) ~164
Paid: 2.99 USDC via x402 (scheme exact), the same $2.99 scan details as on the website. Runs the AI readiness scan for one website and returns every check, the score breakdown and the prioritized fixes as JSON. Call once without `payment` to get the x402 payment requirements, then again with `payment`. Payment is settled only if the scan completes. If the call fails or times out after you pay, call get_scan_details again with the same arguments and the same payment to get the result; you are never charged twice.
| Name | Type | Req | Description |
|---|---|---|---|
| payment | string | – | x402 v2 PAYMENT-SIGNATURE header value (base64 JSON payment payload) |
| url | string | yes | Website URL, e.g. https://example.com |
No output schema declared.

scan_site Free AI readiness scan ~119
Free. Checks a website's robots.txt rules for AI crawlers (GPTBot, OAI-SearchBot, ChatGPT-User, PerplexityBot, ClaudeBot, Google-Extended, CCBot), llms.txt, schema.org JSON-LD, title and meta description, content in raw HTML, and sitemap. Returns a 0 to 100 score and grade, plus a link to unlock the checks and prioritized fixes for $2.99.
