mcp-use

mcp-use is an open-source toolkit for building applications around the Model Context Protocol. It includes components for MCP servers, clients, and agents that invoke external tools.

TypeScript developers can define typed tools and create MCP Apps with React-based views. Python packages also provide ways to connect models and agents to MCP servers.

The toolkit includes project scaffolding, local development commands, and an Inspector for checking tools and interfaces. Built servers can be connected to compatible AI clients, while managed hosting is offered separately.

The source code is distributed under the MIT license. A working agent still needs configured MCP servers, model access, and hosting; any external model or infrastructure charges are not covered by the free toolkit.
