Install
pip install world-model-mcp
cd /path/to/your/hermes/project
python -m world_model_server.cli install-hermes \
--etch-project YOUR_PROJECT_ID \
--etch-token wm_YOUR_APP_TOKEN
Verify
# Restart Hermes; check its MCP client logs for the world-model-mcp handshake. # Or use install-hermes-provider to run the Elixir-native memory provider path.
How it works
Two Hermes paths ship: install-hermes registers world-model-mcp as an MCP server Hermes calls (stdio), and install-hermes-provider installs the Elixir-native memory-provider variant. Pick the one that matches how you run Hermes today.
