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 who work with ai coding, knowledge graph and context graphs and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install World Model MCP

before you install - you'll need

Set WORLD_MODEL_AUDIT_LOG before connecting.

Claude Code

claude mcp add saravananjaichandar-world-model-mcp -- uvx world-model-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "saravananjaichandar-world-model-mcp": {
      "command": "uvx",
      "args": [
        "world-model-mcp"
      ]
    }

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

pypi package world-model-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.SaravananJaichandar is GitHub-verified and matches the repo owner
