Overview
Is this MCP server actually working? We connect as an MCP client (initialize + tools/list), check every tool has a usable inputSchema and description, that named tools exist, and optionally run one sample call on a read-only tool. Pass / fail / couldn't-verify per check with a signed receipt. We never sign in or call tools that change things. $0.10 per call. Not charged for errors or "need more detail" answers.
