What problem does it solve?
This Skill provides a structured approach to building MCP servers that enable LLMs to interact with external services through well-designed tools. It standardizes design patterns, validation, error handling, and documentation to reduce boilerplate and improve reliability across Python (FastMCP) and Node/TypeScript (MCP SDK) implementations.
Core Features & Use Cases
- Structured tool registration patterns for MCP servers in both Python and TypeScript.
- Schema-driven input validation using Pydantic (Python) and Zod (TypeScript).
- Reusable infrastructure patterns including API clients, error handling utilities, and consistent response formatting.
- Guidance for end-to-end workflows and evaluations to ensure maintainable, testable MCP servers.
Quick Start
Create a new MCP server project and register a sample tool using the patterns provided in this Skill. For example, scaffold a Python MCP server named example_mcp and register a simple health_check tool that reports server status.
