- Deployment-ready tooling with local, self-hosted, and FastMCP Cloud options.
- High-level abstractions for tools, resources, and prompts, with schema generation from type hints.
Use Cases
- Building secure MCP services that expose internal data and functionality to LLMs.
- Converting existing OpenAPI/FastAPI apps into MCP services.
- Architecting scalable MCP deployments with proxies, composition, and multiple transports.
Technical Highlights
- Pythonic, minimal-boilerplate API designed for testing and production readiness.
- Supports STDIO/HTTP/SSE transports and multiple client transports for flexible deployments.
- Apache-2.0 license, active community, frequent releases, and strong adoption in MCP ecosystems.
