Cyphrex

This gives your AI agents a blockchain-backed identity system with behavioral guardrails and an immutable audit log. You connect to Cyphrex's remote endpoint over streamable HTTP, which means no local setup beyond pointing your MCP client at their hosted URL. The source doesn't detail specific tools or prompts exposed, but the pitch is clear: verifiable identity for agents, enforced behavior policies, and a permanent record of actions. Reach for this if you're building multi-agent systems where you need accountability, want to prove an agent did or didn't take certain actions, or need to enforce constraints that survive across sessions. One-line config in Claude Desktop or Cursor gets you connected.
