MCP Agents - Example FastMCP Server

A simple Model Context Protocol (MCP) server built with FastMCP that demonstrates basic tool implementation.

Features

greet: Greet a user by name

Installation

This project uses uv for package management and just for task running. Make sure you have both installed:

# Install uv if you don't have it curl -LsSf https://astral.sh/uv/install.sh | sh # Install just if you don't have it # On macOS with Homebrew: brew install just # Or with cargo: cargo install just

Then build the project:

just build

Usage

Running the MCP Server

To start the MCP agents server:

just run

Using with MCP Clients

You can use this server with any MCP-compatible client. The configuration depends on how you want to run the server:

Option 1: Local Development (using source code)

For development or when running from a local clone:

{ "mcpServers": { "mcp-agents": { "command": "uv", "args": ["run", "mcp-agents"], "cwd": "/Users/means/repository/mcp-agents", "env": {} } } }

Option 2: PyPI Installation (recommended for end users)

Once published to PyPI, users can use this simpler configuration:

{ "mcpServers": { "mcp-agents": { "command": "uvx", "args": ["amajakai14_mcp-agents"] } } }

Alternative with pipx:

{ "mcpServers": { "mcp-agents": { "command": "pipx", "args": ["run", "amajakai14_mcp-agents"] } } }

Option 3: Version Pinning

To pin to a specific version:

{ "mcpServers": { "mcp-agents": { "command": "uvx", "args": ["amajakai14_mcp-agents==0.1.0"] } } }

For Claude Desktop

Add any of the above configurations to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%/Claude/claude_desktop_config.json

Testing the Tools
