Configuration

If you're running multiple IDEs with MCP server and want to connect to the specific one, add to the MCP server configuration:

"env": { "IDE_PORT": "<port of IDE's built-in webserver>" }

By default, we connect to IDE on 127.0.0.1 but you can specify a different address/host:

"env": { "HOST": "<host/address of IDE's built-in webserver>" }

To enable logging add:

"env": { "LOG_ENABLED": "true" }
