Make phone calls on macOS using FaceTime.
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
# Phone
Make phone calls on macOS using FaceTime. This tool uses the native macOS `tel:` URL scheme to open FaceTime and initiate calls.
## Requirements
- macOS (the tool will return an error on other platforms)
- FaceTime app installed and signed in
## Tool
Use `phone` for agent-initiated calls.
### Actions
- `call` - Initiate a phone call to the specified number
- `check` - Check if FaceTime is available on this Mac
### Parameters
| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| action | string | Yes | Action to perform: "call" or "check" |
| phone | string | For call action | Phone number to call (E.164 format recommended, e.g., +15551234567) |
### Examples
```json
{
"action": "call",
"phone": "+15551234567"
}
```
```json
{
"action": "check"
}
```
### Response
The tool returns a JSON object with:
- `success`: boolean indicating if the call was initiated successfully
- `callId`: unique identifier for the call (if successful)
- `message`: status message
- `method`: method used ("facetime" for successful calls)
## Notes
- This tool only works on macOS

How to install
mdr add metaspartan/cybara/phone@sha256:834743407dc2d9b4The 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.
