The MCP server provides local stdio tools for MCP-compatible clients that need to validate signed agent execution receipts.

This demo validates signed execution evidence.
It does not prove semantic correctness of the tool output.
It does not prove that the policy itself is correct.
It does not protect against a compromised signer.
It does not replace sandboxing, IAM, access control, monitoring, or human approval.
Do not upload secrets, private keys, confidential evidence bundles, or production receipts.
