What/Why

What are you proposing?

FastMCP is a higher-level framework that provides a more complete, production-ready abstraction for building MCP-compatible servers. FastMCP includes built-in support for key features such as authentication, API auto-generation, documentation (via OpenAPI), and output stream abstraction (stdio, SSE, etc.), offering a more Pythonic and developer-friendly experience.

What users have asked for this feature?

Discussed in PR #32

What problems are you trying to solve?

FastMCP improves developer productivity and provides more useful features. We can utilize various features when we implement new features. It simplifies code, supports faster prototyping, and aligns well with enterprise needs.

What is the developer experience going to be?

FastMCP offers many useful features such as OpenAPI document generation, authentication, etc. I expect that we can reduce the code complexity with FastMCP.

Are there any security considerations?

No. FastMCP is well known framework and it will help us when we make security features.

Are there any breaking changes to the API

MCP protocol behavior remains the same. But we have to modify entire codes.

Are there breaking changes to the User Experience?

No.
