Summary
A persistent memory layer for Claude that survives conversation resets. It exposes tools for locking context as immutable snapshots, hybrid semantic search across stored knowledge, and NLI-based conflict detection to catch contradictions in your project documentation. You also get built-in ticket management with state machines, document ingestion with AI chunking, and multi-project isolation. Authentication runs through OAuth2 on first connect. Reach for this when you're tired of re-explaining your codebase every session or need Claude to remember decisions, architecture constraints, and project context across weeks of work. Connects via streamable-http to a hosted endpoint at mcp.stompy.ai.
