A production-grade MCP server that wraps tool execution in cryptographic governance and audit trails. Every tool call passes through a five-gate firewall (statistical, causal, regression, evidence, human-compatible explanation), gets signed with hybrid Ed25519 plus post-quantum SLH-DSA, and lands in a Merkle transparency log. You get 115+ tools across VPN tunnels, encrypted mail and file storage, agent identity passports, peer trust ceremonies, memory with semantic search, billing provisioning, and sub-agent orchestration. Reach for this when you need verifiable decision records for compliance frameworks like EU AI Act, SOC 2, or GDPR, or when delegating high-stakes operations to autonomous agents that require independent validator quorum approval before execution.
