You can configure the inspector by creating a muppet.config.js/muppet.config.ts file in the root of your project. The configuration file should export an object with the following properties:
import { defineInspectorConfig } from "muppet-kit";
export default defineInspectorConfig({
// ... inspector config
// The inspector will automatically load the config from the file
});- The idea for this project was inspired by the official MCP Inspector and their amazing work.
