MCP server for browser automation using Playwright with profile management, page registry, and multi-browser support
AI Security Review
scanned 17d ago · by lpm-firewall-aiThe manifest points to browser automation entrypoints and defines no install lifecycle hooks. The flagged process output is captured for startup diagnostics and written locally, with no source evidence of exfiltration or malicious execution.
Static reason
One or more suspicious static signals were detected.
Trigger
A user invokes browser automation and an extension browser fails to start.
Impact
No external command output disclosure or other attack effect was established.
Mechanism
The package captures bounded browser process output and writes it to a temporary diagnostic log.
AI rationale
The manifest points to browser automation entrypoints and defines no install lifecycle hooks. The flagged process output is captured for startup diagnostics and written locally, with no source evidence of exfiltration or malicious execution.
Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json identifies the module entrypoints and CLI exports.
- Both module entrypoints validate browser launch requests before handling them.
- The server manager spawns a managed HTTP server process as part of its operation.
- Browser process output is captured for launch diagnostics and written to a local temporary log only when extension startup fails.
