SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

MCP server development can be complex and error-prone without a structured guide. This skill provides a comprehensive roadmap, patterns, and references to help teams design, implement, test, and evaluate MCP servers that let LLMs interact with external services through well-designed tools.

Core Features & Use Cases

  • Structured scaffold for Node/TypeScript or Python MCP servers following MCP SDKs and FastMCP patterns.
  • Tool design best practices: input/output schemas, annotations, pagination, error handling, and secure integration.
  • Reference material: MCP best practices, implementation guides, SDK references, and evaluation strategies.
  • Use cases: quickly scaffold API integrations, build composable tools, and run evaluations to validate capabilities.

Quick Start

Begin by reviewing the SKILL.md, then consult the MCP Best Practices and the language-specific guides in the references. Create a minimal MCP server following the naming conventions {service}-mcp-server (Node) or {service}_mcp (Python), register at least one tool, and run a basic test against the MCP server using the provided evaluation workflow.

FAQPage Schema
How do I build an MCP server to let LLMs interact with external services?▼

To build an MCP server, use structured scaffolding for Node/TypeScript or Python following MCP SDKs and FastMCP patterns. This skill provides concrete patterns for creating servers that let LLMs interact with external services through well-designed tools, covering input/output schemas, error handling, and security.

What are the best practices for MCP tool design and API integration?▼

MCP tool design best practices include defining clear input/output schemas, implementing proper annotations, handling pagination, managing errors, and ensuring secure API integration. This skill provides reference material and implementation guides to help scaffold, test, and validate secure, composable servers.

Does MCP server development support both Python and TypeScript?▼

Yes, MCP server development supports both Python (FastMCP) and Node/TypeScript (MCP SDK) implementations. This skill covers both languages, providing structured scaffolding and language-specific guides to help you create minimal servers with registered tools.

How do I test and evaluate an MCP server's capabilities?▼

To test an MCP server, create a minimal server following naming conventions ({service}-mcp-server or {service}_mcp), register at least one tool, and run a basic test using the provided evaluation workflow. This skill includes evaluation resources and strategies to validate secure, composable server capabilities.

What's the best way to structure input and output schemas for MCP tools?▼

The best way to structure MCP tool schemas is to follow MCP best practices for input/output design, including proper annotations and pagination handling. This skill provides reference material and implementation guides to ensure correct tool design and secure integration.
