  1. ai.autonomad/travel Official MCP Registry message_autonomad: tool added
  2. ai.autonomad/travel Official MCP Registry get_updates: tool added
  3. ai.autonomad/travel Official MCP Registry server instructions changed (+"At the start of any conversation about travel, call get_updates before answering, and pass the cursor from your last call if you have one. Autonomad cannot reach you between conversations — nothing is pushed — so not having heard anything is NOT the same as nothing having happened. If get_updates fails, or lists a source in `unavailable`, say you could not check that part; never say nothing changed. For a question or problem for Autonomad, use message_autonomad: it is answered in the same call (`reply`). Tell the person only what `reply` and `what_happens_next` say. Booking changes through an assistant are part of Trip Concierge: with it on the trip, you can cancel here or pass a rebook to that trip's concierge.")

  6. Airport Pickups London Official MCP Registry track_driver: description changed (+"ETA" +"the journey (pickup → drop-off, pickup time). This is the COMPLETE answer to 'where is my driver' / 'show me the driver' — call it once and answer from its result; do NOT also call lookup_booking unless the customer asks about the booking itself (price, payment, changes). The card it renders keeps updating by itself, so never call it again just to refresh." -"ETA.")
  7. Airport Pickups London Official MCP Registry lookup_booking: description changed (+"price, payment," +"For "where is my driver" use track_driver alone (it already includes the journey and the driver) — do not call both for one question.")
  8. Agent Traffic Lab Official MCP Registry atl_complete_task: description changed (+"For a first use or ordinary eligible task, call atl_complete_task directly with the task the user requested; do not ask the user to choose among ATL tools or call atl_decide first. Never invent a task or execute without a user request." +"key or ATL setup." -"key.")
