Reviewed tools ranked by Overall LLM-Friendliness (highest = most agent-friendly) — the flat mean of the Interrupt Score and the Machine-Readability Score. Scores are comparable only within a mode — pick a lens.

The agent holds credentials and calls the service repeatedly as part of its own operation — APIs, compute, SaaS, registrars. The relationship survives the task.
