Attestation Proof Validation And Verification

Drop-in Treeship attestation for MCP tool calls

Unique: Provides verification specifically for MCP tool call attestations, validating that proofs correspond to actual tool invocations with claimed metadata — enables third-party validation of tool calls without re-execution

vs others: More focused than generic cryptographic verification libraries because it understands MCP tool call context; more practical than blockchain-based verification because it uses standard cryptography without distributed consensus overhead
