mcp-use/mcp-use

The fullstack MCP framework to develop MCP Apps for ChatGPT / Claude & MCP Servers for AI Agents.

What it solves

mcp-use is a TypeScript framework designed to simplify the creation, testing, and deployment of Model Context Protocol (MCP) servers, ChatGPT plugins, and Claude connectors. It removes the friction of manual wiring by providing a typed system for tools and interactive user interfaces.

How it works

The framework builds upon the official MCP TypeScript SDK v2, adding a layer of high-level abstractions. It uses Zod schemas to ensure that data flowing between tools, structured results, and UI components is fully typed. A key feature is the "Native Views" system, which allows developers to bind React components directly to MCP tools, enabling the creation of interactive apps that can be rendered within AI chat interfaces like ChatGPT.

Who it’s for

It is intended for developers building AI agents and extensions that require structured tool-calling capabilities and rich, interactive visual interfaces beyond simple text responses.

Highlights

  • Native Views: Bind React components to tools to create interactive UI experiences within AI conversations.
  • Built-in Inspector: A browser-based tool for invoking and debugging tools and views in real-time.
  • Agent-First Workflow: Includes a CLI for headlessly invoking tools, capturing screenshots of views, and scaffolding projects.
  • Integrated Tunneling: Built-in support to expose local servers to the internet for testing with Claude and ChatGPT.
  • High Performance: Optimized stateless runtime with high operations-per-second benchmarks compared to other MCP frameworks.
