Cathedral — Persistent Memory for AI Agents is a Model Context Protocol (MCP) server: Persistent memory and drift detection for AI agents across session restarts. In practice that means any MCP-compatible AI assistant can call Cathedral — Persistent Memory for AI Agents's tools directly — the model decides when to use them in a conversation or agent run.
You can run Cathedral — Persistent Memory for AI Agents two ways: connect to the hosted endpoint at https://cathedral-ai.com/mcp with no local install, or run it on your own machine via the Python package cathedral-mcp (via uvx).

The current release is v1.1.0, published under the MIT license, with source at AILIFE1/Cathedral on GitHub, where it has earned 10 stars.
