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.

Install

pip install cwn-crewai-trust-gate

Usage

from crewai import Agent, Task, Crew
from crewai_trust_gate import MintActionReceiptTool, VerifyReceiptTool

auditor = Agent(
    role="receipt auditor",
    goal="Verify every consequential action has a tamper-evident receipt",
    tools=[VerifyReceiptTool()],
)

deployer = Agent(
    role="deploy engineer",
    goal="Deploy safely, leave a receipt for every promotion",
    tools=[MintActionReceiptTool()],
)

Tools

Tool Purpose
