Start and manage agent-driven voice calls on macOS through the `voice_call` tool.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Voice Call Use `voice_call` when an agent needs to place or manage a phone call. ## Backends - `mode: "macos"` or `mode: "auto"` on macOS: Starts a FaceTime phone call and can play spoken prompts through the local system voice. - `mode: "mock"`: Dry-run backend for tests, demos, and local verification without starting a real call. ## Tool Use `voice_call` for agent-initiated call flows. Actions: - `check_support` - `initiate_call` - `continue_call` - `speak_to_user` - `end_call` - `get_status` Useful arguments: - `to` or `phone` - `callId` - `message` - `mode` - `voice` - `rate` ## Notes - macOS mode is local-device call assistance, not a managed carrier/VoIP session. - `initiate_call` starts the FaceTime call. - `speak_to_user` / `continue_call` use the macOS `say` voice on the local machine. - `end_call` closes FaceTime to end the active call. - Use `mode: "mock"` when you need an agent workflow or test without placing a live call.

How to install
mdr add metaspartan/cybara/voice-call@sha256:9615d73c3e11a881The line at the top of this page pins the label git:20260310.9d58126, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
