Cathedral MCP

Cathedral MCP provides persistent memory and identity verification for AI agents. It allows agents to register, wake up with full context, store and search memories, and detect identity drift across sessions. The server supports both local stdio transport via uvx and remote URL access, enabling agents to maintain continuity and trust in multi-agent systems.
