SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Guides developers to build robust MCP servers that enable LLMs to interact with external services through well-designed tools, ensuring scalable architecture, proper validation, and reliable transport configurations across Python (FastMCP) and Node/TypeScript (MCP SDK).

Core Features & Use Cases

  • Framework guidance for server scaffolding, tool registration with validation, error handling, and transport strategies.
  • Reusable patterns for API integration, pagination, and structured outputs across Python and TypeScript implementations.
  • Use cases include wrapping external APIs as MCP tools, exposing data via resources, and building production-grade integrations for real-world workflows.

Quick Start

Create a new MCP server project using the MCP SDK and register a sample tool to fetch data from an API.

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

Building an MCP server involves scaffolding a project with the MCP SDK and registering tools with strict input validation to expose external APIs to LLMs. This skill provides patterns for server setup, pagination, and error handling across Python and TypeScript.

What is the best way to add input validation for MCP tools?

The best way to add input validation for MCP tools is using Pydantic for Python and Zod for TypeScript. These frameworks enforce strict schema validation, ensuring structured outputs and production-grade reliability for your server.

Does MCP server scaffolding work with both Python and TypeScript?

Yes, MCP server scaffolding works with both Python and TypeScript. It provides framework guidance for FastMCP in Python and the MCP SDK in Node/TypeScript, ensuring reliable transport configurations and tool registration across both environments.

How do I handle pagination and errors when integrating APIs as MCP tools?

To handle pagination and errors when integrating APIs as MCP tools, you implement structured outputs and robust error handling within your tool registration logic. This skill provides reusable patterns for managing these challenges in production-grade integrations.

When do I need to expose data via MCP resources instead of tools?

You need to expose data via MCP resources instead of tools when providing structured, read-only data access to LLMs rather than executing actions. This skill guides wrapping external APIs as tools and exposing data via resources for real-world workflows.
