Install Etch for Cursor

AI-first code editor

Prerequisite: you need a project_id and app_token. Sign up in 30 seconds if you don't have them yet. Free tier, no credit card.

Install

pip install world-model-mcp
cd /path/to/your/project
python -m world_model_server.cli install-cursor \
    --etch-project YOUR_PROJECT_ID \
    --etch-token wm_YOUR_APP_TOKEN

Verify

ls ./.cursor/mcp.json
# Cursor: Settings > MCP > world-model-mcp should show 'connected'.

How it works

The install-cursor command writes a .cursor/mcp.json file into your project. Restart Cursor once and every tool call surfaces in the Etch dashboard.
