ProofLink MCP Server brings iTechSmart proof receipts, verifier access, accountability checks, and AI governance tooling to MCP-compatible agents.

Post-quantum, tamper-evident receipts for consequential agent actions. Four tools (mint_action_receipt, mint_receipt_for_record_change, verify_receipt, audit_my_agent_inventory) signed Ed25519 + ML-DSA-65 (FIPS 204), verifiable offline from the certificate alone. Defaults to PQ-required verify mode (defends against Ed25519-only downgrade by requiring at least one verified PQ leg). Apache-2.0.

MCP-accessible workflow rails for proof-backed agent runs, receipts, callbacks, and handoff packages.

Commercial trust rails for agent work: scoped work orders, rail execution, receipt verification, Trust Ledger records, and Agent Work History.

Pay-per-success public-data result packs for AI agents with free quotes, source URLs, confidence, timestamps, and receipt hashes.
