What data it sees

Do you need an account

No: the server works without sign-in

ClawCall gives your AI agent a phone. Ask ChatGPT, Claude, Grok Bot or any MCP client to call a US business and ClawCall places a real call: it works through the phone menu, waits on hold, talks to whoever answers, can loop you in, and returns the outcome plus the transcript when one was captured. US +1 numbers, English. Sign in with OAuth; no API key in your client. Free trial: 30 calls and 30 minutes, whichever lasts later. Website: https://clawcall.dev

Server tool list (11)

Raw names from tools/list. Only developers need these.

place_callPlace one real outbound US phone call. Call get_calling_guide with topic outbound first — required every time. Returns call_id immediately — poll get_call until lifecycle is finalized, then get_call_transcript before reporting whether the user's goal succeeded. outcome is the phone network, not task success.
place_call_and_waitPlace one outbound US call and wait up to max_wait_seconds (default 45, max 90) for completion. Call get_calling_guide with topic outbound first — required every time. Not for parallel campaigns. If still running, keep polling get_call with the returned call_id.
get_callPoll a call you own. Lifecycle is queued → dialing → answered → finalized. Returns a short transcript tail only. When finalized, read outcome and then get_call_transcript to judge the user's goal. outcome is the phone network, not task success.
get_call_transcriptFull turn-by-turn transcript for a call you own. Use this after lifecycle is finalized to decide if the user's goal succeeded. Do not treat outcome answered as success.
hangup_callCancel or hang up a call you own. Already-finalized calls succeed as a no-op.
list_callsList compact call history for the signed-in user, without transcripts or call instructions. Use a returned id with get_call_transcript to read the conversation before judging the user's goal. direction=inbound requires Unlimited Reserve Plus and an active reserved number.
get_recordingTemporary playable recording URL for a call you own. The URL expires; do not treat it as a permanent link. Offer it after summarizing the result; do not lead with the recording.
get_balanceRead the signed-in user's current plan, leftover prepaid balance, or trial allowance. Use after a quota/plan error or when the user asks what they have left. Explain allowance limits neutrally and preserve returned informational, sign-in, or support links.
get_call_settingsRead the signed-in user's reusable voice and personality, reserved-number state, and inbound-assistant availability. Explains unavailable capabilities through entitlement and number status, with an informational account-access link.
update_call_settingsPatch reusable voice/personality or inbound-assistant settings in separate calls. Global voice and personality work on every account. Reading, changing, or clearing inbound configuration requires Unlimited Reserve Plus and an active reserved number; entitlement errors explain why the setting is unavailable and include an informational account-access link. Returns an acknowledgement only; call get_call_settings afterward when read access is available.
get_calling_guideRequired before any ClawCall work. These guides are maintained and deployed with the ClawCall server. Read outbound before every place_call, and examples when writing task.
