Visual feedback as agent work packets. Stakeholders drop pins on your live app; your AI coding agent reads each pin (selector, screenshot, DOM, thread, acceptance criteria) via MCP and ships the fix.
AI Security Review
scanned 2mo ago · by lpm-firewall-aiNo install hook or covert payload was found, so the source does not establish malware. However, an explicit publishing flow executes project-controlled shell text and handles cloud uploads and authenticated sync, which warrants a warning.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Run the server with a configured license key, or explicitly run pincushion-mcp mobile-wall publish with a deploy command or upload-enabled configuration.
Impact
A malicious or compromised project configuration can run arbitrary commands when the publish action is invoked; selected screenshots and license-authenticated feedback data can leave the machine.
Mechanism
Shell execution from publish configuration, plus authenticated cloud upload and sync.
AI rationale
No install hook or covert payload was found, so the source does not establish malware. However, an explicit publishing flow executes project-controlled shell text and handles cloud uploads and authenticated sync, which warrants a warning.

Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The mobile publish command executes a deploy command through a shell; the command can come from the project wall configuration.
- The mobile publish workflow reads a selected screenshot and uploads its base64 content with a license-key header.
- Starting the server with a configured license key enables cloud sync and sends that key to the configured Pincushion endpoint.
- Server startup emits product telemetry to a configurable PostHog host unless the user opts out.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook and no self-dependency.
- The shell execution is reachable only through the explicit mobile-wall publish subcommand.
- The observed network destinations and file handling are consistent with the package's feedback, cloud-sync, and mobile publishing features.
- The license helper masks keys for display rather than exposing full values.
