SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires fastmcp, pydantic, aiohttp, sqlite3, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill eliminates the complexity and context bloat of building Model Context Protocol servers, enabling you to create professional-grade integrations with 85-93% token reduction.

Core Features & Use Cases

  • Progressive Disclosure: Implement gateway patterns that load capabilities on-demand instead of all upfront.
  • Tool Optimization: Reduce tool description tokens by 65-70% through proper annotations and patterns.
  • Use Case: Imagine you need to build an MCP server with 10+ API endpoints. Use this Skill to create a single gateway tool that achieves 93% baseline context reduction while maintaining full functionality.

Quick Start

Use the creating-mcp-servers skill to build a FastMCP v2 server for integrating with your company's project management API.

Architecture Decision Guide

  • 1-3 simple tools? → Standard FastMCP with optimized descriptions
  • 5+ related capabilities? → Gateway pattern with progressive disclosure
  • Optimize existing server? → Apply mandatory patterns for consistency
  • Package for distribution? → Use MCPB bundling with proper manifest generation.
