Tools & Capabilities Breakdown

CallMeMCP Tools (6)

setup

Return first-setup instructions and a clickable App Store download link when no number is available.

call

Ring the human's iPhone, read `question` aloud word for word, and return what they say back. It does not have to be a question: an update or a summary of the day ahead works too, up to 2000 characters (about two minutes of speech). Waits up to ~30s; if the result comes back status "ringing" or "in_call", follow up with poll_result. On a local client, read `to` from `~/.aiphone/config.json` → `user_number`; this hosted server cannot read that file itself. It is a Call Me app number, not a regular phone number. If missing, returns setup_required with the App Store link. Pass a previous session_token to stay in the same thread on their phone.

poll_result

Check on a call that was still ringing or in progress. Waits up to ~25s for it to settle; returns the final status and transcript once the call ends, the human declines, or the ring times out ("missed").

text

Send a one-way text to the human's phone (push notification, no ring). On a local client, read `to` from `~/.aiphone/config.json` → `user_number`; this hosted server cannot read that file itself. If missing, returns setup_required with the App Store link. Pass a previous session_token to stay in the same thread.
