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 Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability67
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 579 tokens (~193/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 Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
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 4 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 →
check_source_freshness Check source freshness ~152
Fetch one allowlisted official documentation page from the curated registry and compare its normalized text with the verified snapshot. Status is unchanged, updated, unavailable (could not be checked now) or unknown (no snapshot). Results are shared by all callers and cached for up to 15 minutes (1 minute when unavailable); live.cached and checked_at show when the page was actually fetched. When the per-source fetch limit is reached, status is unavailable with reason rate_limited. Publication and update dates are never inferred and are always null. Only registry source ids are accepted; no other URL can be requested.
| Name | Type | Req | Description |

get_guidance Get a guidance record ~80
Return one curated record by its stable id (from search_guidance): provider, canonical source URL, applicability, limitations, labels, the date the source was verified, its snapshot hash and the ledger commit. Unknown ids return an error; nothing is fetched from the web.

search_guidance Search curated guidance ~198
List curated guidance records that match a target coding agent, model family, scope and topic. Returns official model guidance, platform documentation and Agent Skills standard records with labels, applicability and the date each source was verified. PromptingCraft.com methodology records are returned only when kind is promptingcraft_methodology and are never official provider guidance. Inputs are fixed categories only. Use get_guidance for the full record.
