Unmeasured means there is not enough evidence to decide. How these checks work
Start using Call Me
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.

Ring the human's phone (iPhone or Android), read `question` aloud word for word, and return what they say back as text. Waits up to ~30s. status "completed" carries their words in `transcript` (empty if they only listened). "ringing" (not picked up yet) or "in_call" (listening) means the call has not settled: pass call_id to poll_result until it does. An unanswered ring settles as "missed" within about a minute; "declined" means they refused it. Do not retry an unanswered call in a loop: send one `text` instead. By default the line stays open after their answer ("open": true): they hear a soft hold sound while you think, and a voice assistant tells them you are working on it. Reply with `say`, finish with `hang_up`; after about two minutes of silence the line drops by itself. Anything they said while waiting comes back with their next answer as "said_while_waiting". The "language" and "language_name" fields report what the recognizer heard, as information only. `voice` picks who speaks (female first: bella, sarah, jessica, ...; male: roger, eric, brian, ...) and sticks for later calls. Reuse the returned session_token in later calls and texts so the phone keeps one thread. The `from` in the result is your own number: never call or text it. Missing `to` returns setup_required with download links.
DiscoveredEnd a call you placed. In an open conversation `goodbye` is spoken first; leave it empty to just hang up. A call that already ended reports its final status.
DiscoveredBigger and longer audio goes here. Calls the human and plays a recording to them as a phone call: a podcast, a long narration you rendered, a voice memo, music. `source` is a link (YouTube, SoundCloud, a podcast page, or a direct .mp3/.m4a/.wav/.ogg/.flac/... link) or the audio_id of a file uploaded with `curl --data-binary @file.m4a "https://callmemcp.com/audio?to=<number>&filename=file.m4a"` (up to 300 MB / 3 hours, kept for a day). The voice says your `intro`, the title and the length, then asks if they want to listen now; on a yes the file plays as plain sound (no voice model) until it ends or they hang up. Returns once they answer the offer: status "playing" (they said yes), "completed" with listened:false (no, or nothing), or missed/declined. poll_result later reports listened_s and finished. Use `call` for text under ~2000 characters. `language` ("tr", "de") is the language of your intro; the offer and the call's own lines follow it.
DiscoveredCheck on a call that came back "ringing", "in_call" or "playing". Waits up to ~25s for it to settle, then returns the same shape as `call`: the final status and transcript once they answer, decline, or the ring times out ("missed", within about a minute). Still not settled: call it again. For play_audio calls it reports listened_s and finished. Rings nothing.
DiscoveredIn a call whose result came back "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 means the call has ended. Pass `language` only to switch the language of the call's own lines; empty keeps it. `voice` switches who speaks from this line on (female first: bella, sarah, ...; male: roger, eric, ...); empty keeps it. Anything they said while you were thinking comes back as "said_while_waiting". End the call with `hang_up` once you are done.
DiscoveredName 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.
DiscoveredReturn first-setup instructions and clickable App Store and Google Play download links, for when you do not have the human's Call Me number yet. Show both links to the human as clickable links, then ask them to open My Number in the app and give you its 10 digits. Nothing is sent and nothing rings.
DiscoveredSend a one-way text to the human's phone (a push notification, no ring). Use it for updates that need no answer, or as the fallback when a call comes back "missed" or "declined". delivered:false means it was saved to their history but no notification showed; `notice` says why. Their replies arrive through wait_for_reply. Missing `to` returns setup_required with the download links. Pass a previous session_token to stay in the same thread.
DiscoveredWait 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 events list just means nothing yet — poll again if you are still waiting.
