Enables AI agents and MCP hosts to anchor file hashes to Bitcoin via OpenTimestamps and verify proofs, ensuring files existed before a given time with privacy-preserving local hashing.
Document verification MCP server enabling AI agents to verify file authenticity by computing SHA-256 fingerprints locally and checking Bitcoin-anchored proofs via OpenTimestamps.
Enables MCP clients like Claude and Cursor to protect local files with SELLAT proofs of existence, track their Polygon and Bitcoin anchoring status, add a qualified eIDAS timestamp seal, and verify files against proof files or evidence packages. Files are hashed on the user's machine, so only the SHA-256 hash is sent to the service.
Enables agents and gateways to seal each action into a tamper-evident W3C PROV record backed by a signed Merkle transparency log, and to fetch tree heads, inclusion and consistency proofs, verify records, and trace artifact lineage through six typed MCP tools.
