Simple FastMCP Server

This repository contains a minimal MCP server built with FastMCP 2.0. It exposes two tools:

  • add(a: int, b: int) -> int: Returns the sum of two numbers.
  • greet(name: str) -> str: Returns a friendly greeting.

Local Development

Prerequisites:

  • Python 3.9+
  • pip

Install dependencies:

pip install -r requirements.txt

Run the server locally over HTTP:

python my_server.py

The MCP endpoint will be available at http://localhost:8000/mcp.

Optional: Test with a simple client script.

Create client_test.py:

import asyncio
from fastmcp import Client

async def main():
    async with Client("http://localhost:8000/mcp") as client:
        result = await client.call_tool("greet", {"name": "FastMCP"})
        print(result)

asyncio.run(main())

Run it:

python client_test.py

Deploy to FastMCP Cloud

FastMCP Cloud hosts MCP servers from your GitHub repository and provides a URL like https://your-project-name.fastmcp.app/mcp ([1]).

Steps:

  • Push this repository to GitHub (ensure requirements.txt is present).
  • Sign in to FastMCP Cloud with your GitHub account and create a project.
  • Set the entrypoint to my_server.py:mcp (Cloud imports the server object and ignores __main__) ([2]).
  • Deploy; your server becomes available at https://<project>.fastmcp.app/mcp.

Notes:

  • Cloud automatically installs dependencies from requirements.txt ([1]).
  • Entry-point configuration accepts file.py:object_name syntax if you rename the server instance ([1]).
