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 3mo ago · by lpm-firewall-aiThe scanner's credential/network and shell findings map to documented Pincushion synchronization, opted-out telemetry, and an explicit user-supplied deployment command. Direct inspection found no lifecycle hook or concrete stealthy/exfiltration chain.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Running the MCP with configured cloud credentials, or explicitly invoking mobile-wall publish with a deploy command.
Impact
Normal service authentication and requested local deployment execution; no install-time mutation, remote payload execution, or broad agent-control hijack was found.
Mechanism
Opt-in product sync, telemetry, and user-directed deployment automation.
AI rationale
The scanner's credential/network and shell findings map to documented Pincushion synchronization, opted-out telemetry, and an explicit user-supplied deployment command. Direct inspection found no lifecycle hook or concrete stealthy/exfiltration chain.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with medium false-positive risk.
Evidence for AI clean decision
- Runtime cloud sync sends the configured license key to Pincushion's Supabase endpoint.
- The explicit mobile-wall publish command can run a user-supplied deploy command through a shell.
- Optional telemetry uses a stable hash derived from the license key.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- The entrypoint enables cloud sync only when a key, flag, or configured key file is present.
- Telemetry documents opt-out controls and hashes rather than sends the raw license key.
- Editor MCP configuration writes occur only through explicit setup/claim workflows and are project-gated.
