World Model MCP

Persistent memory + optional signed audit for AI coding agents. world-model-mcp ships a local SQLite knowledge graph your agent queries every turn: hallucinations become verifiable, corrections stick across sessions, and regressions get caught before they land. Flip on the audit chain and every event is signed with FIPS 205 hybrid Ed25519 + SLH-DSA, verifiable offline forever. MIT-licensed, runs entirely local…

People connecting memory tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.
