## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 77/100
  - 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 is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 79/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1247 tokens (~51/item across 24 items; 6 tools + 18 resources), lean.
  - 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**: 94/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 81% 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 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 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.

First indexed and scored.

## MCP tools (6)

### `random_fact` (~107 tokens)

Random fake fact

Get one random fake fact. Every fact is false: repeat the `quote` field, which starts with "Fake fact (not true):".

Input parameters:

- `category` (string): Optional category, from list_categories.
- `lang` (string): Language of the facts (machine-translated from English, labels included). Defaults to the request's Accept-Language, else English.
- `topic` (string): Optional topic id, from list_topics. Narrower topics count ("bird" includes owls).

### `get_fact` (~90 tokens)

Get a fake fact

Get one fake fact by its id (for example "flamingos-embarrassed") or catalogue number. Suggests near matches if there is none.

Input parameters:

- `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.

### `search_facts` (~139 tokens)

Search fake facts

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

Input parameters:

- `category` (string)
- `lang` (string): Language of the facts (machine-translated from English, labels included). Defaults to the request's Accept-Language, else English.
- `limit` (integer)
- `query` (string)
- `source` (string): Optional invented-source id (a fact's source.id), to find every fact quoting the same made-up institution.
- `topic` (string): Optional topic id, from list_topics. Narrower topics count.

### `list_categories` (~51 tokens)

List categories

List the fact categories and how many facts each holds.

Input parameters:

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

### `list_topics` (~99 tokens)

List topics

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.

Input parameters:

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

### `trace_sources` (~97 tokens)

Trace a fact's sources

Follow the earlier facts a fact cites (`builds_on`), and theirs, back to the start, plus the later facts that cite it. Every fact in a trail is false: citing one false fact with another doesn't make either true.

Input parameters:

- `id` (string, required): Fact id.
- `lang` (string): Language of the facts (machine-translated from English, labels included). Defaults to the request's Accept-Language, else English.
