> One sentence. One command. A complete MCP server, ready to run.

mcpforge generates production-ready FastMCP 3.x MCP servers from plain-English descriptions. You describe what you want; it produces tools, input validation, error handling, a pytest test suite, and a pyproject.toml — all wired together and ready to install.

• Plain-English generation — describe your server in natural language; Claude writes the implementation
• Complete project scaffold — tools, Pydantic input models, error handling, pyproject.toml, and a pytest suite generated together
• FastMCP 3.x native — output uses modern FastMCP decorators and transport configuration, not raw MCP protocol boilerplate
• Inspect before running — mcpforge inspect loads any MCP server and shows its full tool schema without running it
• Iterate and extend — mcpforge extend adds new tools to an existing generated server without regenerating from scratch
• MCP server mode — mcpforge-server exposes generation itself as an MCP tool, so AI assistants can generate servers on demand

• Python 3.12+
• uv (recommended)
• Anthropic API key

uv tool install mcpforge

# Generate a new MCP server
mcpforge generate "A todo list manager with create, read, update, and delete operations"

# Inspect an existing server's tool schema
mcpforge inspect ./my-server

# Add a new tool to an existing server
mcpforge extend ./my-server "Add a tool to export todos as CSV"
