Qué hace este MCP

Resolves AnchorRegistry identifiers and SHA-256 hashes to public artifact provenance records, including relationships, manifests, timestamps, and status.

Capacidades

Herramientas

3 herramientas
ar_resolve_tree
Resolve the full provenance tree for an AR-ID. Returns every anchor in the tree (root + all descendants) with their relationships, types, manifest hashes, and timestamps. Use this when you need to understand a multi-artifact provenance chain — for example, a research paper anchored as the root with its training dataset and model weights as children.

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['ar_id'], 'properties': {'ar_id': {'type': 'string', 'pattern': '^AR-\\d{4}-[A-Za-z0-9]{7}$', 'description': 'Any AR-ID in the tree. The endpoint walks up to find the root and returns the full tree.'}}}
ar_verify_arid
Resolve an AnchorRegistry AR-ID to its full provenance record. Use this when you encounter an SPDX-Anchor or DAPX-Anchor tag (e.g. in a README, paper, model card, or website) and need to confirm what the artifact is, who anchored it, when, what type it is, and whether the tree has been sealed, retracted, voided, or affirmed. Free, public, no auth required.

ar_verify_by_hash
Resolve an artifact by its SHA-256 manifest hash. Use this when you have the artifact itself but no AR-ID, and want to check whether it has been anchored. Returns the AR-ID and full provenance record if found, or a clear "not anchored" response otherwise.
Esquema de entrada 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['manifest_hash'], 'properties': {'manifest_hash': {'type': 'string', 'pattern': '^[a-fA-F0-9]{64}$', 'description': 'Hex-encoded SHA-256 manifest hash, no 0x prefix, 64 chars'}}}
