   weight 2 · round to Undermind
   Undermind~partialprobed2/10

   Undermind's enterprise page claims 'programmatic queries via API' and integration into 'other tools and workflows,' hinting at automatable/headless use, but there is no CLI, no published API reference, and probes for OpenAPI/API docs all returned 404s. The only concretely documented automation path is the MCP server, which is designed for interactive agent clients (Cursor, VS Code, Claude) rather than headless CI pipelines. Missing for 10: documented API/CLI with auth and examples, evidence of CI/automation usage, and confirmation the enterprise API is publicly accessible rather than bespoke.
