kotlin-sdk vs fastapi_mcp
kotlin-sdk: This Kotlin SDK implements the Model Context Protocol (MCP), offering a standardized way for applications to provide context to LLMs, separating context provision from LLM interaction. It simplifies building MCP clients and servers, supporting various Kotlin platforms and standard communication transports.; fastapi_mcp: FastAPI-MCP allows you to expose your existing FastAPI endpoints as Model Context Protocol (MCP) tools. It offers native integration with FastAPI, including built-in authentication using existing dependencies, and preserves schemas and documentation.

When to choose:
- You already have a FastAPI application and want to expose its endpoints as MCP tools while reusing your existing FastAPI authentication dependencies and Swagger schemas.
- You want to mount the MCP server directly onto your ASGI app or deploy it separately under an MIT license.
When to skip:
- You are building a standalone MCP server from scratch rather than wrapping a FastAPI app; use FastMCP or the official MCP Python SDK.
- You need an actively updated repository (last push was November 2025).
