## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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 2026-08-06.

- **Supply Chain Security**: 86/100
  - No malware found by supply-chain analysis.
  - Known CVEs were checked across the 94 of 98 dependencies we could resolve, so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Dependency health was assessed across the 94 of 98 dependencies we could resolve, so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.

  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 37/100
  - Stability observed for 11 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 90/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 69% of tool parameters carry a description.

## Changelog

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.

### 2026-08-06 (score 69, +1)

No change was recorded against any check on this day. Stability & Change Management went from 33 to 37. That category is still filling its 30-day observation window: 10 days of observed history at the previous scan, 11 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (7)

### `authorize` (~100 tokens)

Authorize this agent

Start or continue the device-flow authorization. Call with no arguments to begin: show the returned verification_url to the human and ask them to open it and approve. Then call again passing the same `code`, a few seconds apart, until status is 'approved' (token saved automatically) or 'expired' (start over). Grants 20 attestations for 24 hours.

Input parameters:

- `code` (string): The code from a previous authorize call, to resume polling.

### `attest_file` (~147 tokens)

Attest a file

Compute the SHA-256 fingerprint of a local file (streamed, never sent anywhere) and attest it: the server timestamps it and returns a signed attestation. Requires a credential — run 'authorize' first, or set IMGAUTH_API_KEY. Optional declared metadata (titolo/autore/anno/note) is bound to the signature.

Input parameters:

- `anno` (string): Declared year/version (optional).
- `autore` (string): Declared author (optional).
- `note` (string): Declared free-text note (optional).
- `path` (string, required): Absolute or relative path to the local file.
- `titolo` (string): Declared title of the work (optional).

### `get_certificate_pdf` (~138 tokens)

Get the certificate PDF

Get the signed certificate PDF for an attested work, saving it to a local file. Pass `attestation` (the exact object returned by attest_file) right after attesting, to mint a freshly-signed PDF. Pass only `hash` to recover an already-archived certificate instead (no credential needed).

Input parameters:

- `attestation` (object): The full object returned by attest_file, to mint a new PDF.
- `hash` (string, required): The SHA-256 fingerprint (64 hex chars).
- `save_to` (string): Local file path to save the PDF to (default: ./certificato_<hash12>.pdf).

### `verify_file` (~160 tokens)

Verify a file against a certificate

Compute the SHA-256 of a local file and check it against a declared hash/attestation, plus verify the HMAC signature server-side (no file bytes are ever sent). Pass the fields as read from the certificate (hash, attestazione, hmac, and any declared titolo/autore/anno/note).

Input parameters:

- `anno` (string)
- `attestazione` (string): The attestation string from the certificate.
- `autore` (string)
- `hash` (string): Declared SHA-256 to compare against (from the certificate).
- `hmac` (string): The HMAC signature from the certificate.
- `note` (string)
- `path` (string, required): Local file to verify.
- `titolo` (string)

### `verify_certificate` (~123 tokens)

Verify a certificate's signature

Verify the HMAC signature of a certificate's attestation (+ declared metadata, if any) without checking against any local file. Confirms authenticity and integrity of the declared data, not that a given file matches.

Input parameters:

- `anno` (string)
- `attestazione` (string, required): The attestation string from the certificate.
- `autore` (string)
- `hash` (string, required): The SHA-256 fingerprint from the certificate.
- `hmac` (string, required): The HMAC signature from the certificate.
- `note` (string)
- `titolo` (string)

### `check_anchor` (~63 tokens)

Check the Bitcoin anchoring proof

Check whether a fingerprint has an OpenTimestamps proof, optionally saving the .ots proof file to disk.

Input parameters:

- `hash` (string, required): The SHA-256 fingerprint.
- `save_to` (string): Local file path to save the .ots proof to, if it exists.

### `service_status` (~28 tokens)

Check service status

Get the traffic-light status of the attestation service (worker, archive, signer, Bitcoin anchor).
