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.
MCP server for offline verification of signed artifacts — receipts, manifests, and audit bundles. MIT licensed, works without accounts or API calls. Tools: self_test, verify_receipt, verify_bundle, explain_artifact.
Provides cryptographic truth infrastructure for AI agents, enabling them to seal content with SHA-256 and Ed25519, verify receipts, anchor them to Bitcoin via OpenTimestamps, generate citations, and audit chains of receipts.
