Merkle Batch Verifier

Batch-verifies SHA-256 Merkle inclusion proofs for payment batches, settlement sets, and ISO 20022 message streams. Detects tampered or misrouted transactions before settlement finality. Exports an AP2 cryptographic_mandate artifact. DORA Art.12 · BIS CPMI PFMI Principle 9.

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

  
Run the AINumbers MCP tool `verify_merkle_batch`. Task: Batch-verify Merkle inclusion proofs using SHA-256 (DORA Art.12 / BIS CPMI PFMI Principle 9).
Call it with arguments: {"policy_parameters":{"proof_entries":[],"merkle_root":"0000000000000000000000000000000000000000000000000000000000000000"}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
