FAQPage Schema

How do I build an MCP server that connects to external APIs?▼

Build an MCP server by defining tools with input schemas, integrating external API calls, and implementing asynchronous I/O and error handling. This Skill provides step-by-step guidance for Python (FastMCP) and TypeScript (MCP SDK) to create reusable adapters that let Claude interact with services like GitHub, project management systems, or data platforms.

What's the difference between Python and TypeScript for MCP server development?▼

Both Python (FastMCP) and TypeScript (MCP SDK) support MCP server development with identical core principles: tool registration, input validation, and API integration. Choose Python for rapid prototyping with Pydantic validation or TypeScript for Node.js environments with Zod schema enforcement. This Skill covers best practices for both.

Do I need to validate tool inputs when building an MCP server?▼

Yes, strict input validation is essential for MCP servers. Use Pydantic (Python) or Zod (TypeScript) to define and enforce schemas for every tool, preventing invalid API calls and improving security. This Skill includes validation patterns and error-handling strategies for production-ready servers.

How do I structure an MCP server project for maintainability?▼

Structure MCP projects with modular components: separate tool definitions, API client logic, validation schemas, and error handlers into distinct files. This Skill provides a complete project layout guide, testing scaffolds, and evaluation frameworks for both Python and TypeScript implementations.

Can I handle pagination and large API responses in an MCP server?▼

Yes, MCP servers can manage pagination by implementing limit and offset parameters in tool schemas, iterating through API pages, and formatting responses efficiently. This Skill covers pagination patterns, response formatting, and asynchronous I/O for handling large datasets across multiple API calls.

What security considerations should I implement in an MCP server?▼

Implement input validation, API rate limiting, credential isolation, and error messages that don't expose sensitive data. This Skill includes security best practices for tool design, external service integration, and handling authentication tokens safely in production MCP servers.
