SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps developers design and implement MCP servers using the MCP SDKs.

Core Features & Use Cases

  • Guidelines for structuring MCP projects in Python (FastMCP) or Node/TypeScript (MCP SDK).
  • Tools-registration patterns, input validation (Pydantic/Zod), and error handling standards.
  • Examples and best practices for transport setup (stdio, streamable HTTP) and resources.

Quick Start

Create a new MCP server project under service-mcp-server, install dependencies with npm install (TypeScript) or pip install -r requirements.txt (Python), implement at least one tool using the MCP SDK, and run the server using the recommended transport (stdio or streamable_http).

FAQPage Schema
How do I build an MCP server with TypeScript or Python?▼

To build an MCP server, structure your project using the MCP TypeScript or Python SDKs, implement tools with proper registration patterns, and run the server using stdio or streamable HTTP transport.

What is the best way to validate tool inputs in an MCP server?▼

The best way to validate tool inputs in an MCP server is using Zod for TypeScript or Pydantic for Python, ensuring robust definitions and proper error handling for external API integrations.

How do I structure an MCP server project for scalable tool registration?▼

Structure an MCP server project by organizing tool registration patterns, setting up transport choices like stdio or streamable HTTP, and following best practices for scalable MCP server design.

Can I use streamable HTTP transport instead of stdio for an MCP server?▼

Yes, you can use streamable HTTP transport instead of stdio for an MCP server. The MCP SDKs support both transport choices to fit different networking requirements and deployment contexts.

Do I need Pydantic or Zod to handle errors in MCP server tools?▼

You need Pydantic or Zod to handle input validation in MCP server tools. These libraries provide the standards for error handling and ensuring robust tool definitions within the MCP SDK.

Why does my MCP server need clear tooling and best practices?▼

Your MCP server needs clear tooling and best practices to create robust tool definitions for LLM agents. Following SDK standards ensures proper validation, scalable design, and reliable external API integration.
