FAQPage Schema
How do I build an MCP server to expose external APIs to LLMs?

You build an MCP server by scaffolding tool registration, enforcing runtime input validation, and configuring streaming HTTP or stdio transports. This skill provides end-to-end guidance, reference implementations, and example scripts for both Python and TypeScript SDKs.

What is the best way to validate tool inputs in MCP server development?

Validating tool inputs in MCP server development requires enforcing runtime input validation and applying tool annotations during tool registration. This skill provides reference materials and evaluation-ready tooling to implement these best practices.

Does this MCP builder support both Python and TypeScript SDKs?

Yes, this MCP builder supports both Python and TypeScript SDKs. It provides reference implementations and best-practice patterns for both languages to help teams design and validate servers with modular architecture.

How do I register a basic tool in an MCP server using TypeScript?

To register a basic tool in an MCP server using TypeScript, you scaffold the server and define the tool with proper annotations and runtime validation. The skill includes example scripts in the reference directory for quick setup.

What transports can I use for MCP server implementation?

You can use streaming HTTP or stdio transports for MCP server implementation. The skill guides you through planning, implementation, testing, and evaluation to ensure robust tool registration and modular architecture.

When do I need tool annotations in MCP server architecture?

You need tool annotations in MCP server architecture when exposing external services to LLMs to ensure well-designed, structured interactions. This skill enforces tool annotations and modular architecture to accelerate MCP adoption safely.
