FAQ from Wechat Dev Mcp

What prerequisites are needed?

Node.js v18+, WeChat DevTools installed with the Service Port enabled, and an open mini‑program or mini‑game project.

How do I connect to a running DevTools instance?

Use the launch tool (opens DevTools and a project) or the connect tool (connects via WebSocket, default ws://localhost:9420).

What should I do if I get a "Connection refused" error?

Ensure DevTools is running and the Service Port is enabled in the settings. Then retry the connection.

Can I use page tools (e.g., `get_element`) on a mini‑game?

No. Page tools return clear errors if used on a game project. Use evaluate, call_wx_method, or the game_* tools instead.

How can I verify everything works after making code changes?

Run the check_health tool. It checks connection, page path, network, console errors, and project type.
