How we check: we connect without logging in and ask for the list of tools. We never send credentials and never pay. Tools that don't state a price are never called; for tools that do, we send at most 2 unpaid calls to read the payment request. We don't make test purchases from MCP servers yet. Signed records: raw data page · free quick check (JSON)
