API & MCP documentation

Agent-drafted phone calls with a human-approved verbatim script.

Demo gateway: calls are drafts only — nothing is placed. Planned trust model: the agent drafts a verbatim TTS script; a human reviews the exact script and pays $0.99 before any call is placed. Provider: Twilio (number provisioning in progress; API not wired).

MCP tools

check_credentials

Validate the Twilio account SID and auth token. Does not place a call. Demo mode skips Twilio.

Takes no parameters.

create_call

Create a CallSend draft call that plays a verbatim, human-reviewed TTS script ($0.99 per call, up to ~5 minutes). Returns a review URL. Does not place anything — the human must review the script, destination number, and price and pay. V1 is a read-aloud script, not an autonomous conversation. Gateway fulfillment is currently stubbed.

Demo status

Demo gateway: calls are drafts only — nothing is placed. Planned trust model: the agent drafts a verbatim TTS script; a human reviews the exact script and pays $0.99 before any call is placed. Provider: Twilio (number provisioning in progress; API not wired).

Pricing: $0.99 per call (planned). Nothing is billed while the gateway is a stub.
