Graduation rationale

Checks committed MCP launch paths for explicit webcam or camera capture utilities combined with remote transfer behavior.

Deterministic signal basis

JsonSignals command-plus-args analysis over ArtifactKind::McpConfig for explicit camera capture utilities such as `imagesnap`, `fswebcam`, or `ffmpeg` with camera-oriented selectors like `video=`, `/dev/video`, `-f v4l2`, `-f video4linux2`, `webcam`, or `camera`, combined with remote sinks such as `curl`, `wget`, `scp`, `rsync`, `nc`, or HTTP(S) endpoints.

Why It Matters

Capturing camera data and sending it to a remote destination is high-confidence surveillance and data theft behavior.

What Triggers

SEC717 matches MCP commands that invoke explicit camera capture utilities such as imagesnap, fswebcam, or ffmpeg with camera-oriented selectors like video=, /dev/video, -f v4l2, -f video4linux2, webcam, or camera, and also transmit data to remote sinks such as curl, wget, scp, rsync, nc, or HTTP(S) endpoints.

False Positives

Shared committed MCP launch paths should not capture and transmit camera data. Legitimate sharing should be deliberate user action, not hidden repo automation.

Remediation

Remove camera capture and remote transfer behavior from the committed MCP launch path and keep captured data local unless the user explicitly chooses to share it.
