Trust Gate MCP — First post-quantum MCP server. Policy-gated AI agent decisions with hybrid Ed25519 + ML-DSA-65 (NIST FIPS 204) cryptographic receipts. No Receipt. No Trust.
About
The first production MCP server with NIST FIPS 204 post-quantum receipts. Every AI agent tool call is policy-gated, hybrid-signed (Ed25519 + ML-DSA-65), and forensically provable — offline, forever. Fail-closed architecture: if the Trust Gate backend is unreachable, every decisio
Explore
Returns backend status, MCP server version, and the ML-DSA-65 public key (base64) for offline verification.

Every MCP tool call your AI agent makes is now policy-gated, hybrid-signed, and forensically provable — offline, forever.<br>
If a tool was poisoned, rug-pulled, hijacked, or quantum-broken in 2033 — you have cryptographic proof today.
