How do I test my MCP server?

You can use the official MCP Inspector to verify tool functionality and transport mechanisms like stdio or streamable HTTP.

What is an MCP server?

An MCP (Model Context Protocol) server is a specialized backend that enables LLMs to interact with external data and services through defined tools and resources.

Does this help with deployment?

Yes, it includes guidance for local development and one-click cloud deployment specifically optimized for MCP servers.

Why are evaluations included in the process?

Evaluations ensure that an LLM can effectively use the tools you have built to solve complex, real-world tasks accurately and consistently.

Which languages are supported by this skill?

The skill provides detailed implementation patterns for both Python (using FastMCP 2.0) and Node.js/TypeScript.
