INDIVIDUAL MCP TOOL

hash_data

Compute sha256 over the JCS-canonical bytes of any JSON value — the same payload_hash anchor_action would produce — without anchoring.

verify_proof — Re-compute sha256(JCS(data)), Schnorr-verify the signature, and re-derive the bech32 address from the public key — all locally, no chain query.
verify_proof_onchain — Chain-backed verification over the hosted operator node: looks up the bundle's txid (mempool / confirmation), and — when confirmed — checks the on-chain KAP1 payload commits to the bundle's payload_hash / parent_txid / action_type, then walks the parent chain.
