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]).
