cwn-crewai-trust-gate 0.1.0

CrewAI tools for Trust Gate post-quantum receipts (Ed25519 + ML-DSA-65, verifiable offline).

crewai-trust-gate

CrewAI tools for Trust Gate post-quantum, tamper-evident receipts on consequential agent actions.

Trust Gate receipts are signed Ed25519 + ML-DSA-65 (FIPS 204) by the hosted MCP server (no local signing key). Each receipt is verifiable offline from the certificate alone. The hosted server defaults to PQ-required verify mode; set TRUST_GATE_REQUIRE_PQ=false to allow Ed25519-only receipts.
