How does this skill optimize AI context usage?

It provides strategies for returning high-signal information, implementing character limits, and designing tools for specific workflows rather than just mirroring raw API endpoints.

What is agent-centric design in MCP?

It is a design philosophy that focuses on how AI agents actually use tools, prioritizing actionable error messages, human-readable identifiers, and consolidated workflow operations.

Does this skill support both Python and TypeScript?

Yes, it includes specific implementation guides, best practices, and project structure templates for both the Python (FastMCP) and Node/TypeScript SDKs.

What is an MCP server?

An MCP (Model Context Protocol) server is a standard-based service that exposes tools and resources to LLMs, allowing them to perform actions like fetching data or calling external APIs.

How do I test my MCP server safely?

The guide recommends using the provided evaluation harness or running the server in a separate environment like tmux to avoid hanging the main development process during testing.
