Does this skill help with input validation?

Yes, it provides guidance on using Pydantic for Python and Zod for TypeScript to ensure robust tool input validation and clear error messaging.

Which programming languages are supported by this skill?

The guide provides specific implementation workflows and best practices for both Python (using FastMCP) and Node/TypeScript (using the MCP SDK).

What is an MCP server?

An MCP (Model Context Protocol) server acts as a bridge that allows LLMs to interact with external services and APIs through standardized, well-designed tools.

Why focus on agent-centric design?

Agent-centric design ensures tools are optimized for an LLM's context window, providing high-signal data and actionable errors rather than raw API dumps that consume tokens.

How do I test my MCP server safely?

It is recommended to use an evaluation harness or run the server in a separate process (like tmux) to avoid hanging the main development process during testing.
