Gives Claude cryptographic identity continuity across sessions. Exposes tools for `/wake` (full memory reconstruction), `/memories` (store and search), `/anchor/verify` (drift detection via SHA-256 corpus hashing), and `/verify/peer` (agent-to-agent trust scoring). Useful when you need an agent to maintain stable identity after restarts or model swaps, not just retrieve past context. The hosted API at cathedral-ai.com handles storage and hashing server-side, so you skip the infrastructure. The drift benchmark claims 0.013 average drift over 10 sessions versus 0.204 for raw retrieval. Supports both stdio for local Claude Desktop and streamable-http for remote API integrations.
