4Mint a post-quantum receipt for one CRM record change. Old/new values are carried as SHA-256 hashes. Works with any CRM (Relaticle, hosted CRMs, custom).
Rank a CALLER-PROVIDED list of MCP tools by worst-regret if they act, with a signed receipt. Cannot auto-discover the inventory -- MCP does not allow that; the caller must pass it in.
Mint a post-quantum receipt for an arbitrary consequential agent action.
Verify a Trust Gate receipt from the certificate alone (offline). require_pq=True (default via OAO_REQUIRE_PQ) FAILS if the ML-DSA-65 or SLH-DSA legs are missing -- defends against signature-stripping downgrade attacks.
Overview
What is Trust Gate Mcp?
Trust Gate Mcp is an MCP server that provides post-quantum, tamper-evident receipts for consequential agent actions. It integrates with the open-source OpenAgentOntology signing primitive and is designed for agents that need auditable, cryptographically verifiable trails.
How to use Trust Gate Mcp?
Install the package and run the server locally with pip install mcp "openagentontology[pq]" then python server.py. For containerized deployment, build the Docker image and run it with a volume mount on /data/oao for key persistence: docker build -t trust-gate-mcp . and docker run -p 8081:8081 -v trust-gate-data:/data/oao trust-gate-mcp.

FAQ from Trust Gate Mcp
What is the signing primitive used?
The OpenAgentOntology mint_receipt primitive: Ed25519 + ML‑DSA‑65 + SLH‑DSA.
How do I run Trust Gate Mcp locally?
Install the package with pip install mcp "openagentontology[pq]" and then run python server.py.
What is required for production deployment?
A volume mount on /data/oao is required for persistent signing keys; without it the key rotates per restart and breaks long‑running verification chains.
Does Trust Gate Mcp auto‑discover other servers?
No – the MCP protocol does not allow auto‑discovery of other servers.
Is verification possible offline?
Yes – verify_receipt works offline from the certificate alone, no database required, and defaults to PQ‑required mode.
