## 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)

- **Supply Chain Security**: 13/100
  - Malware scan not yet available for this package.
  - CVE data not yet available for this package.
  - No install/post-install scripts declared.
  - Dependency-health data not yet available.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 7 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 0/100
  - Schema quality not yet verified: our sandbox run of this package did not complete, so we have no schema to assess.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: our sandbox run of this package did not complete, so we have no schema to compare.
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: our sandbox run of this package did not complete, so we have no tool definitions to assess.
- **Capabilities**: 0/100
  - Protocol version not yet verified: our sandbox run of this package did not complete, so we never saw its MCP handshake.

**Unverified: 4 categories.** Categories scored 0 because our sandbox run of this package has not given us the schema these checks need to read. That is a gap on our side rather than a finding about the package, and we only credit what we can confirm, so the score stands at 0 until the capture succeeds. We are working through the fleet, so this normally clears without any action from you.

## MCP tools (5)

### `orphograph_anchor_file` (~144 tokens)

Anchor a local file to the Bitcoin chain via Orphograph. Reads the file locally, computes SHA-256 and SHA-512 in-process, and transmits ONLY those fingerprints. The file body never leaves the device. Returns a receipt id, a receipt URL, and calendar attestation counts.

Input parameters:

- `c2pa_manifest_hash` (string): Optional SHA-256 hex of a C2PA manifest the receipt should reference (coexistence mode).
- `label` (string): Optional human-readable label (max 200 chars). Stored on the receipt; do not include sensitive content.
- `path` (string, required): Absolute or relative path to the file to anchor.

### `orphograph_anchor_folder` (~137 tokens)

Anchor a whole folder (a dataset) to the Bitcoin chain via Orphograph. Every file is hashed locally into an RFC-6962 Merkle tree; ONLY the manifest (relative paths + SHA-256 digests + the root) is transmitted — no file body leaves the device. Returns a receipt id and a hosted certificate URL; each file stays independently verifiable via an inclusion proof.

Input parameters:

- `label` (string): Optional human-readable label (max 200 chars). Stored on the receipt; do not include sensitive content.
- `path` (string, required): Absolute or relative path to the folder (dataset bundle) to anchor.

### `orphograph_anchor_output` (~178 tokens)

Anchor a string of generated OUTPUT (an AI agent's result, a model response, a transcript, any text) to the Bitcoin chain — without writing a file first. Hashes the UTF-8 text in-process and transmits ONLY the SHA-256/512 fingerprints; the text never leaves the device. Use this to prove an exact output existed at a specific time. Returns a receipt id, a receipt URL, and calendar attestation counts.

Input parameters:

- `c2pa_manifest_hash` (string): Optional SHA-256 hex of a C2PA manifest the receipt should reference (coexistence mode).
- `label` (string): Optional human-readable label (max 200 chars). Stored on the receipt; do not include sensitive content.
- `text` (string, required): The output text to anchor. Hashed locally; not transmitted.

### `orphograph_verify_receipt` (~70 tokens)

Verify an existing Orphograph receipt against the calendars and Bitcoin chain. Returns the anchored hashes, the calendar attestation counts, and (when available) the Bitcoin block commitment time. Does not require an API key.

Input parameters:

- `receipt_id` (string, required): The receipt identifier issued at anchor time.

### `orphograph_list_vault` (~66 tokens)

List the signed-in subscriber's anchored receipts. Requires ORPHO_API_KEY in the environment. The key is issued from https://orphograph.com/account.html.

Input parameters:

- `limit` (integer): Maximum number of receipts to return (1-500). Defaults to 50.
