What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
$('#out').innerHTML = h; $('#out').classList.add('show');
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

This one needs environment variables set before it will start:
ANTHROPIC_API_KEY (Anthropic API key, used only by compare_studies for live papers. compare_example and list_examples run offline without it.), NCBI_EMAIL (Contact email sent with PubMed/PMC E-utilities requests (NCBI asks callers to identify themselves). Optional.).
