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

To build an MCP server, you use Python with FastMCP or TypeScript with the MCP SDK to design well-scoped tools that let LLMs execute stable, controlled interactions with external APIs while maintaining safety.

What is the best way to handle authentication for MCP server tools?▼

Handling authentication for MCP servers involves implementing rigorous security practices directly within your tool design using the Python FastMCP or TypeScript MCP SDK to ensure safe access to external services.

How do I deploy an MCP server using Docker for production?▼

Deploying an MCP server using Docker involves containerizing your Python or TypeScript implementation to ensure durable, reproducible production use alongside rigorous input validation and error handling.

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

Yes, MCP server development supports both Python using FastMCP and Node/TypeScript using the MCP SDK, allowing you to implement tool design patterns, authentication, and error handling in either environment.

How do I create evaluations and testing for MCP server tools?▼

Creating evaluations for MCP server tools involves building reproducible testing scenarios that verify tool execution end-to-end, ensuring reliable LLM usage and robust production deployment.

What are the best practices for MCP tool design and input validation?▼

MCP tool design best practices include enforcing rigorous input validation, clear tool annotations, and strict error handling to ensure LLMs execute well-scoped, stable tools safely.
