## 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 2026-10-18.

- **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**: 72/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 448 tokens (~149/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**: 13/100
  - Stability observed for 4 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.

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-10-18 (score 69, +1)

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-10-16 (score 68, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-10-15 (score 67, 0)

- [security] Tool “proof_fetch_offer” rewrote its description, which is the text the model reads
- [functional improvement] Stability: unverified → 0.03

### 2026-10-14 (score 67)

First indexed and scored.

## MCP tools (3)

### `proof_fetch_preflight` (~134 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): Public HTTP(S) document URL. No credentials, private networks, authenticated pages or browser rendering.

### `proof_fetch_offer` (~103 tokens)

Show the offer and prices

Returns the offer and request schema without buying. Full cited text: 25 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` (~211 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 25 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 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): Public HTTP(S) document URL. No credentials, private networks, authenticated pages or browser rendering.
