    Your MCP Server Is "Connected." Your Agent Still Can't Use It. Here's the Gap.

    <p>The client shows a green dot. The tool icon is in the list. Your agent's config file has the server registered. Every signal says "connected" — and the agent still can't do the thing you added the tool for. It either ignores the tool entirely, or calls it and gets back somethi…
