MCP-Forge

MCP-Forge

MCP-Forge is a scaffolding tool designed to quickly bootstrap new MCP (Model Context Protocol) server projects. It generates a well-structured project with boilerplate code, example tools, resources, and testing utilities, allowing you to focus on building your server's capabilities.

⚠️ Early Project: This is an early version of MCP-Forge. The API, generated structure, and features might change as the MCP ecosystem evolves. Feedback and contributions are welcome!

Features

• Generates a complete Python project structure for an MCP server.
• Includes separate server entry points for SSE and stdio transports.
• Provides example HelloWorld tool and HelloWorld/UserProfile resources.
• Sets up Pydantic models for clear input/output schemas.
• Uses uv for dependency management and task running.

Installation

It's recommended to run mcp-forge using uvx (from uv), which handles temporary environments:

# Ensure uv is installed
uvx mcp-forge --help

Alternatively, you can install it globally or in a dedicated environment using pip:

pip install mcp-forge
mcp-forge --help

Usage

Creating a New MCP Server

The primary command is new, which scaffolds a new server project.

# Example using uvx (recommended)
uvx mcp-forge new my-awesome-server

# Example if installed globally/in environment
# mcp-forge new my-awesome-server

This command will:

1. Create a new directory named my-awesome-server.
2. Generate a complete project structure inside this directory (see below).
3. Set up a basic server with example tools and resources ready to run.

Options for new command:

• --description or -d: Provide a custom description for your project (used in pyproject.toml and README.md).

  uvx mcp-forge new my-project -d "My amazing MCP server"
  

• --python-version or -p: Specify the minimum required Python version (default: >=3.10).

  uvx mcp-forge new my-project -p ">=3.11"
  

Generated Project Structure

MCP-Forge creates a project with the following structure:

my-awesome-server/
├── my_awesome_server/           # Python package for your server code
│   ├── __init__.py              # Package initialization
│   ├── server_stdio.py          # Entry point for running the server with stdio transport
│   ├── server_sse.py            # Entry point for running the server with SSE transport (HTTP)
│   ├── interfaces/              # Base classes/interfaces for tools and resources
│   │   ├── __init__.py
│   │   ├── resource.py
│   │   └── tool.py
│   ├── resources/               # Implementation of resources

│   │   └── user_profile.py      # Example dynamic resource with URI parameters
│   ├── services/                # Services for managing tools and resources
│   │   ├── __init__.py
│   │   ├── resource_service.py  # Handles resource registration and routing
│   │   └── tool_service.py      # Handles tool registration and execution
│   └── tools/                   # Implementation of tools
│       ├── __init__.py
│       └── hello_world.py       # Example tool with input/output schemas
├── pyproject.toml               # Project metadata and dependencies (using Hatch)
└── README.md                    # README template for the generated project

Next Steps After Generation

1. Navigate into the newly created project directory:

   cd my-awesome-server
   

2. Set up the Python environment and install dependencies:

   uv venv
   uv pip install -e .
   

3. Run the server using either SSE or stdio:

   # Run SSE server (default: http://0.0.0.0:6969)
   uv run python -m my_awesome_server.server_sse
   
   # OR Run stdio server
   # uv run python -m my_awesome_server.server_stdio
   

About MCP

The Model Context Protocol (MCP) is a specification for enabling communication between language models (or other clients) and external tools/services (servers). It defines how servers can expose capabilities like tools and resources in a standardized way.
