Category Search and Retrieval
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 Security77
- 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 is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability79
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 1247 tokens (~51/item across 24 items; 6 tools + 18 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management3
- Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage94
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 81% 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 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 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_fact Get a fake fact ~90
Get one fake fact by its id (for example "flamingos-embarrassed") or catalogue number. Suggests near matches if there is none.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | – | Fact id. |
| lang | string | – | Language of the facts (machine-translated from English, labels included). Defaults to the request's Accept-Language, else English. |
| no | integer | – | Catalogue number. |
No output schema declared.
No examples provided.
list_categories List categories ~51
List the fact categories and how many facts each holds.

No output schema declared.
No examples provided.
list_topics List topics ~99
List the topics facts are filed under: id, label, broader topic or category, and how many facts each holds (narrower topics included). Each topic is a real thing; every fact about it is false. The full vocabulary, with Wikidata matches, is at /taxonomy.json.
| Name | Type | Req | Description |

search_facts Search fake facts ~139
Find fake facts by topic. Plain words or a sentence both work ("owls", "anything about cheese?"); plurals and word starts match.

|---|---|---|---|
| category | string | – | – |
| lang | string | – | Language of the facts (machine-translated from English, labels included). Defaults to the request's Accept-Language, else English. |

|---|---|---|---|
| id | string | yes | Fact id. |
