## 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**: 69/100
  - 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 69/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 516 tokens (~172/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**: 23/100
  - Stability observed for 7 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 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (3)

### `proof_fetch_preflight` (~164 tokens)

Check a public page (free)

Free: checks a public URL and returns fetchability, provenance, hashes, deterministic injection indicators and a free preview of the first 1,000 or so characters of text (short pages come back whole); not a safety guarantee. No payment or purchase. Example: {"url":"https://example.com/","maxChars":30000}.

Input parameters:

- `maxChars` (integer): Maximum normalized characters to extract. Free preflight returns metadata plus a preview of about the first 1,000 characters.
- `url` (string, required): Required: the address of one public web page or PDF, for example https://example.com/; a bare domain such as example.com also works. Not a search phrase or placeholder. No credentials, private networ…

### `proof_fetch_offer` (~105 tokens)

Show the offer and prices

Returns the offer and request schema without buying. Full cited text: 1,000 free extractions with a free key (no card), then $0.01 a page either way: a 500-page card pack for $5, or $0.50 per Stripe MPP call, which returns the page plus an API key holding 49 more. Cited text uses POST /v1/evidence with a caller-generated idempotency key. Example arguments: {}.

### `proof_fetch_evidence` (~247 tokens)

Get cited page text (uses a key credit)

Fetch a public URL and return its cited, paragraph-addressable text with integrity hashes and a receipt. Uses one credit from a ProofFetch key, and only when extraction succeeds. Needs the key sent as the MCP request header Authorization: Bearer <key>: a free key holds 1,000 extractions (no card, POST /v1/keys/free or the ProofFetch home page); a paid key holds 500 for $5.00 (sold on the ProofFetch home page). Example: {"url":"https://example.com/"}.

Input parameters:

- `idempotencyKey` (string): Optional. The same value on a retry within 7 days returns the stored result without using a second credit; a call without one is a new purchase.
- `maxChars` (integer): Maximum normalized characters to extract. Free preflight returns metadata plus a preview of about the first 1,000 characters.
- `url` (string, required): Required: the address of one public web page or PDF, for example https://example.com/; a bare domain such as example.com also works. Not a search phrase or placeholder. No credentials, private networ…
