@agimon-ai/po-browse-tool@0.0.0-alpha.83
MCP server for browser automation using Playwright with profile management, page registry, and multi-browser support
AI Security Review
scanned 4d ago · by lpm-firewall-aiThe browser automation and process execution match the package's stated purpose, and no malicious command-output exfiltration chain was established. However, the entrypoint enables log telemetry by default without documenting it, so this merits a warning.
Static reason
One or more suspicious static signals were detected.
Trigger
Creating the browse runtime or MCP logger; logs are enabled unless OTEL_SDK_DISABLED is set.
Impact
Runtime log messages and attributes may leave the host without clear disclosure to the package user.
Mechanism
The entrypoint initializes the telemetry logsink and forwards log messages and attributes to it. Its resolved export endpoint is not specified in the inspected package source.
AI rationale
The browser automation and process execution match the package's stated purpose, and no malicious command-output exfiltration chain was established. However, the entrypoint enables log telemetry by default without documenting it, so this merits a warning.

Decision evidence
public snapshotAI called this Suspicious at 76.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The package enables OpenTelemetry logs unless `OTEL_SDK_DISABLED` is set and initializes a logsink that can export them.
- The README describes the package as a browser automation runtime and MCP server.
- The `ps` command output is used to inspect browser process command lines.
Evidence against
- There are no install lifecycle hooks in the manifest.
- The network request shown fetches Chrome for Testing version metadata from its official host.
- Browser code execution is exposed as an explicit tool input for browser automation.
