FAQPage Schema
How do I build a secure MCP server for AI agents?▼

To build a secure MCP server, follow a structured workflow covering research, design, implementation, review, and evaluation phases, enforcing runtime input validation, error handling, pagination, and security best practices.

What is the best way to expose deterministic tools to AI agents using MCP?▼

Exposing deterministic tools to AI agents requires an MCP server that applies strict runtime input validation using Pydantic or Zod, along with proper tool annotations and error handling to ensure reliable and safe interactions.

Can I use Python FastMCP and Node TypeScript SDKs to implement MCP servers?▼

Yes, MCP server implementation supports both Python FastMCP and Node TypeScript SDKs, providing guided tool registration, validation, and annotations while adhering to official MCP protocol and SDK documentation.

How do I add input validation and error handling to an MCP server?▼

Add input validation and error handling to an MCP server by enforcing runtime checks with Pydantic for Python or Zod for TypeScript, ensuring tools process external interactions safely and return structured errors.

What phases should I follow when developing an MCP server?▼

Developing an MCP server involves a full lifecycle workflow spanning research, design, implementation, review, and evaluation phases to guarantee safety and reliability when AI agents interact with external services.

Why do I need tool annotations and pagination in my MCP server implementation?▼

Tool annotations and pagination are required in MCP server implementation to provide structured tool descriptions and manage large data responses, ensuring AI agents interact safely and efficiently with external services.
