Every field above is reproduced as the server published it at the time shown. The description and the annotations are claims by the server's author. Toolpin does not call tools, so we cannot tell you whether a tool does what it says.

What we can tell you is whether the claim changed. The hash covers the fields the MCP specification defines, so a vendor build stamp does not move it but a rewritten description does. See how we monitor, or this server's change history.
