FAQPage Schema

How do I build an MCP server to expose external API tools?▼

You build an MCP server by scaffolding it with Python using FastMCP or Node/TypeScript with the MCP SDK, then registering external API endpoints as structured tools with clear annotations and JSON outputs.

What is the best way to validate inputs in a Model Context Protocol server?▼

The best way to validate MCP server inputs is by enforcing strict schemas using Pydantic for Python implementations or Zod for Node/TypeScript implementations to ensure reliable LLM-assisted integrations.

Does the MCP SDK support TypeScript and Python for server development?▼

Yes, the MCP SDK supports cross-language server development by providing the MCP SDK for Node/TypeScript and FastMCP for Python, enabling robust scaffolding for external API integrations.

How do I handle errors and pagination when integrating external APIs in an MCP server?▼

You handle errors and pagination by applying the skill's best-practices templates for external API integrations, ensuring structured JSON and Markdown outputs that support reliable data automation.

What security practices should I follow when creating MCP tools for external services?▼

When creating MCP tools for external services, you should follow enforced security best practices, including strict schema validation, structured outputs, and clear tool annotations to protect external service interactions.
