SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Efficiently exposing external APIs to LLMs is hard due to fragmented tooling, inconsistent patterns, and the need for strong typing, validation, and error handling.

Core Features & Use Cases

  • End-to-end MCP server development guidance from planning to evaluation for Python and TypeScript implementations.
  • Best-practice tool design, including input validation with Zod/Pydantic, robust error handling, and clear tool annotations.
  • Reference architectures and examples for streamable HTTP and stdio transports, tools, and resources.

Quick Start

Launch the MCP server in stdio mode and register a sample tool to validate the end-to-end workflow.

FAQPage Schema
How do I build an MCP server to expose external APIs to LLMs?▼

Best practices for MCP server tool registration include designing clear tool annotations, enforcing input validation with Zod or Pydantic, implementing robust API client design, and handling pagination to ensure production-grade tool interactions.

Can I implement MCP servers using TypeScript and Python?▼

Yes, you can implement MCP servers using TypeScript and Python. This skill provides language-specific guidance for both, covering end-to-end development from planning through implementation, testing, and evaluation for your chosen language.

Does MCP server development support both stdio and streamable HTTP transports?▼

MCP server development supports both stdio and streamable HTTP transports. The skill provides reference architectures and examples for secure transport patterns, allowing you to choose the best fit for your external service integration.

What's the best way to validate tool inputs when creating an MCP server?▼

The best way to validate tool inputs when creating an MCP server is using Zod for TypeScript implementations and Pydantic for Python, ensuring robust type checking and secure API client design before processing requests.

Why do I need pagination and error handling in my MCP server tools?▼

You need pagination and error handling in MCP server tools to manage large data responses from external APIs and prevent LLM workflow disruptions. This ensures robust, production-grade interactions and clear tool annotations.
