What is the FastMCP Integration Application Demo MCP Server?

A modular application API interface based on FastMCP, integrating a demo of the MCP server, FastAPI interface and LLM Agent processing capabilities |

What it actually does

  • Modular Design — Clear separation of concerns (API, LLM, MCP) for easy extension and maintenance
  • Dual Run Modes —
  • api mode: Runs the FastAPI server, requires a separately running MCP server
  • mcp mode: Runs the MCP server directly for testing or connection by other clients
  • LLM Integration — Supports using OpenAI (or other extensible LLMs) to process tool outputs or execute in Agent mode
  • Agent Mode — Provides an /api/agent/process endpoint for the LLM to autonomously select and call MCP tools

More MCP options
