SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires mcp, and includes scripts (resource) components.

What problem does it solve?

MCP server development often involves assembling robust, scalable integrations that let LLMs safely interact with external services. This Skill guides you to implement production-grade MCP servers using either Python FastMCP or Node/TypeScript MCP SDK.

Core Features & Use Cases

  • Guidance on project structure, input validation with Pydantic/ Zod, tool registration, error handling, and security considerations.
  • Practical workflows for implementing core infrastructure, tools, resources, and tests, plus phase-driven development from setup to evaluation.
  • Examples and best practices for using stdio and Streamable HTTP transports, plus lifecycle management and monitoring.

Quick Start

Initialize your MCP server, register tools with the MCP SDK, and run it using stdio or streamable HTTP to expose your tools.

FAQPage Schema
How do I build a production-grade MCP server with Python or TypeScript?

Build an MCP server using Python FastMCP or Node MCP SDK to expose non-destructive tools for external API interactions. This skill guides project structure, tool registration, input validation with Pydantic or Zod, error handling, and security considerations for production-grade servers.

What is the best way to validate inputs and handle errors in an MCP server?

The best way to validate inputs and handle errors in an MCP server is using Pydantic for Python or Zod for TypeScript. This skill covers implementing robust validation schemas, registering tools securely, and managing error handling to ensure safe external API interactions.

Does this MCP server guidance support both stdio and streamable HTTP transports?

Yes, this guidance supports both stdio and streamable HTTP transports for MCP servers. It provides examples and best practices for configuring transport options, managing server lifecycle, and monitoring operations in production environments.

Can I expose non-destructive tools for external API interactions using MCP?

Yes, you can expose non-destructive tools for external API interactions using MCP. This skill covers tool registration, security considerations, and testing workflows to ensure your MCP server safely interacts with external services without destructive side effects.

What testing and evaluation workflows are recommended for MCP server development?

Recommended testing and evaluation workflows for MCP server development include phase-driven processes from initial setup to final evaluation. This skill provides practical workflows for implementing tests, validating tool behavior, and assessing infrastructure before production deployment.

When should I use FastMCP versus the Node MCP SDK for my server?

Use FastMCP for Python-based MCP servers requiring Pydantic validation, or Node MCP SDK for TypeScript environments using Zod. This skill guides both paths, covering project structure, transport options, and security considerations specific to each framework.
