The server needs auth, so these tool definitions were read from the publisher's open-source package pypi:factql-mcp, started in a container with placeholder values and the network off, on 2026-11-14. Tool definitions do not depend on the token, so this is what an authorized user loads, unless the server hides tools by plan or role.
