mcp-use

Two complementary halves make up mcp-use, an MIT-licensed open source project at about 10,500 GitHub stars. The original Python library, installable from PyPI, connects any tool-calling LLM to any MCP server and produces working agents in a few lines of code, handling multi-server connections and selecting the right server for a given task; because it is model-agnostic, the same agent code runs against hosted APIs or fully local models. The newer TypeScript side has grown into a fullstack MCP framework scaffolded with create-mcp-use-app: tool definitions flow through typed Zod schemas into structured results, React views can bind directly to tools for interactive interfaces, and a built-in inspector plus a companion CLI handle debugging, headless invocation, and screenshot verification. Documentation at docs.mcp-use.com covers both stacks. The project occupies a useful middle ground, lighter than a full agent platform but more batteries-included than the raw protocol SDKs, which has made it a common starting point for custom MCP clients, servers, and agent prototypes.
