Fastmcp Builder

FastMCP Builder - Claude Code Skill

A comprehensive Claude Code skill for building production-ready MCP (Model Context Protocol) servers using the FastMCP Python framework. This skill provides complete reference implementations, working examples, and proven patterns for creating robust MCP servers with tools, resources, prompts, OAuth authentication, and comprehensive testing.

What is FastMCP?

**FastMCP** is the official high-level Python framework for building MCP servers. It's simpler, faster to develop with, and more maintainable than the low-level MCP SDK. This skill focuses exclusively on FastMCP-based development.

• fastmcp_overview.md - Introduction, when to use FastMCP, key features
• project_structure.md - Recommended structure, file organization, DRY patterns
• tool_patterns.md - 6 tool patterns with complete examples
• resource_patterns.md - 4 resource types (static, dynamic, template, wildcard)
• oauth_integration.md - Complete Google OAuth setup guide
• testing_guide.md - FastMCP Client testing, patterns, best practices

2. Code Examples (`examples/`)

Runnable examples from minimal to complete servers:
