On 2026-10-24 the server answered initialize and tools/list without a sign-in. First answer in 31 ms.

• Whether its tools do the product's job has not been judged yet.
• Checked on 3 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• 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…

• 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").

• say

  In a call placed with keep_open=true, speak `text` to the human and return what they answer, in the same shape as `call`. Only after their previous answer is in. Waits up to ~30s; on "in_call", follow up with poll_result. "open": false…

• hang_up

  End a call you placed. In a keep_open conversation `goodbye` is spoken first (e.g. "Thanks, I'll get on it."); leave it empty to just hang up.

• 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…

• wait_for_reply

  Wait for the human to send something back to this session — texts and voicemail transcripts arrive here. Long-polls up to wait_s (max 30s); returns {events, cursor}. Pass the returned cursor next time to only see new events. An empty…

• set_thread_title

  Name this session's conversation thread on the human's phone (e.g. the project or task you are working on). Shown as the thread title in the app.
