Field notes
The page exposes a single-tool checker and a tools-list endpoint, with sample payloads and a Cursor MCP setup path; its rules are labeled 2026-10-18.1. Findings link to explanatory resources, while the optional outcome report retains the tool name, a description hash when supplied, called/ignored status, optional client label, and timestamp—not raw descriptions or schemas. The public tally omits tool names.
