SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pypdf, pdfplumber, pdf2image, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides a comprehensive guide and best practices for developing high-quality MCP (Model Context Protocol) servers, enabling LLMs to reliably interact with external services and APIs.

Core Features & Use Cases

  • End-to-End Development Guide: Covers research, implementation, testing, and evaluation of MCP servers.
  • Language-Specific Guidance: Detailed instructions for both Python (FastMCP) and Node/TypeScript (MCP SDK).
  • Best Practices: Includes naming conventions, response formatting, pagination, security, and error handling.
  • Use Case: A developer needs to create an MCP server for a new internal API. This Skill guides them through setting up the server, defining tools with Pydantic/Zod, implementing robust error handling, and creating evaluations to ensure LLM compatibility.

Quick Start

Follow the Node/TypeScript guide to set up a new MCP server project.

FAQPage Schema
What is an MCP server and when do I need one for LLM integration?▼

An MCP server enables LLMs to reliably interact with external services and APIs. You need one when integrating language models with external tools, requiring structured research, implementation, testing, and evaluation phases.

How do I build an MCP server using Python or Node TypeScript?▼

Build MCP servers by following language-specific guides: use FastMCP for Python or the MCP SDK for Node/TypeScript. Define tools with Pydantic or Zod, implement robust error handling, and apply naming conventions and response formatting.

What's the best way to structure tools and handle errors in MCP server implementation?▼

The best way to structure MCP server implementation involves following best practices for tool design, response formatting, pagination, security, and robust error handling to ensure reliable LLM compatibility and external API interaction.

Does this MCP development guide support both Python and Node environments?▼

Yes, this MCP development guide supports both environments by providing detailed implementation instructions for Python using FastMCP and Node/TypeScript using the official MCP SDK, covering tool definition and evaluation creation.

How do I test and evaluate an MCP server for LLM compatibility?▼

Test and evaluate an MCP server by creating specific evaluations to ensure LLM compatibility. This involves following the end-to-end development guide covering testing phases, response formatting checks, and security validations.
