How to Set Up and Use Muppet
Muppet is an open-source TypeScript SDK designed to simplify the full lifecycle of Model Context Protocol servers — from development and local testing to production deployment. It provides a web-standards-based API, an MCP Inspector for debugging and AI-assisted testing, and integrations with frameworks like Hono, allowing developers to build, inspect, and ship MCP servers with minimal boilerplate. Teams building custom MCP tools for Claude, ChatGPT, or other AI clients can use Muppet to accelerate development and improve observability of their server implementations.
Prerequisites
- Node.js 18 or later and npm installed
- TypeScript knowledge (the SDK targets TypeScript projects)
- An MCP-compatible client for testing: Claude Desktop, Claude Code, or Cursor
- Familiarity with web server concepts (the SDK uses web-standard patterns)
Install the Muppet core package
Add the Muppet SDK to your TypeScript project.
npm install muppet
# or for Hono integration:
npm install muppet @hono/mcpCreate your MCP server entry point
Import from muppet and define your server with tools, resources, or prompts using the SDK's API.
import { createServer } from 'muppet';
const server = createServer({
name: 'my-mcp-server',
version: '1.0.0',
});
// Register tools, resources, and prompts here
server.start();Use the MCP Inspector for debugging
Muppet includes an Inspector for testing your server during development. Connect it to your running server to view tool calls and responses interactively.
npx @modelcontextprotocol/inspectorBuild and compile your server
Compile the TypeScript project to JavaScript for deployment.
npx tsc
# or if using a build script:
npm run buildRegister the compiled server with your MCP client
Add the server to your MCP client configuration file pointing to the compiled entry point.
Muppet Examples
Client configuration
Claude Desktop config for a Muppet-built MCP server running as a compiled Node.js process.
{
"mcpServers": {
"my-muppet-server": {
"command": "node",
"args": ["/path/to/dist/index.js"]
}
}
}Prompts to try
These prompts assume you have defined tools in your Muppet server. Adapt tool names to match your implementation.
- "What tools are available on this server?"
- "Call the hello_world tool"
- "Use the fetch_data tool with parameter url='https://example.com'"
- "List all resources exposed by this MCP server"Troubleshooting Muppet
Cannot import from 'muppet' — module not found
Ensure you have run 'npm install muppet' in your project directory and that your tsconfig.json moduleResolution is set to 'node16' or 'bundler'. Check the installed version with: npm list muppet
MCP Inspector cannot connect to the development server
Ensure your Muppet server is running and listening on the expected transport (stdio or HTTP). The Inspector from @modelcontextprotocol/inspector should be pointed at the server's URL or connected via stdio depending on your transport choice.
Tools not appearing in the MCP client after registration
Verify that tools are registered before server.start() is called. Check the MCP client logs for connection errors and confirm the compiled output path in your config matches the actual file location.
