What problem does it solve?
Build, test, inspect, install, and deploy MCP servers with FastMCP in Python. Use when creating a new MCP server, wrapping an API or database as MCP tools, exposing resources or prompts, or preparing a FastMCP server for Claude Code, Cursor, or HTTP deployment.
Core Features & Use Cases
- Templates for API wrappers, read-only database servers, and deterministic file processors to scaffold MCP tools quickly.
- Scaffold and template tooling to copy starter templates and replace server name placeholders.
- Tool-first development workflow that emphasizes explicit tool definitions, docstrings, typed parameters, and safe defaults.
- Local validation and testing using the FastMCP CLI to inspect, list, and call tools before integration.
- Client installations and deployment into Claude Code, Claude Desktop, Cursor, or generic HTTP endpoints.
- Environment checks and integration guidance via a small doctor script and templates for deployment readiness.
Quick Start
Run the scaffold_fastmcp script to generate a starter server from templates, then implement your first MCP tool and test locally.
