TL;DR: Cathedral is a local-first, MCP-compatible memory layer that shares context across multiple AI development tools.
Summary: HoppyCat released Cathedral, a local-first, MCP-compatible persistent memory layer for AI agents. Formerly known as soul-stack, it provides memory provenance and context-sharing across stateless context windows for tools like Cursor and Claude Desktop. The project also includes a Windows Terminal fork featuring native command-line agent integration under the Apache 2.0 license.
Why it matters: It solves the problem of context fragmentation by letting developers share a unified local memory across different AI editors and tools. Builders should try integrating Cathedral to maintain context continuity between terminal sessions and IDEs.
