mcp-use

Use it when

• You need to stand up a typed TypeScript MCP server with tools, schemas, and a local inspector without hand-wiring the official SDK, Vite, and debugging tooling yourself
• You are building an MCP app with interactive React views for ChatGPT or Claude and want tool-to-UI contracts, screenshot verification, and tunneling in one framework

What it solves

Not the fit when

• teams standardized on the bare official SDK with no view or inspector needs
• non-TypeScript stacks unless using the separate Python package
• v1 projects without running the documented v2 migration
• exposing the development tunnel to untrusted users without adding application-appropriate authentication and authorization
• consuming third-party MCP servers is secondary here
• browser automation
• LLM inference or model hosting
• Python-first server development (a separate mcp-use Python package covers that)

Install

npx -y create-mcp-use-app@latest (framework itself: npm install mcp-use; headless client: npm install --save-dev @mcp-use/client)

Invoke

Define tools with new MCPServer(...) and server.tool({inputSchema, outputSchema, view}, handler); npm run dev serves the MCP endpoint at http://localhost:3000/mcp with the Inspector at /mcp/inspector; mcp-use dev --tunnel exposes a public URL for testing with ChatGPT or Claude
