@agimon-ai/po-browse-tool@0.0.0-alpha.76
MCP server for browser automation using Playwright with profile management, page registry, and multi-browser support
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe runtime sends telemetry logs by default, but the README does not disclose this behavior and the telemetry endpoint is not established in the inspected package source. The behavior requires explicit runtime creation, and I found no evidence of install-time collection or credential theft, so this warrants a warning rather than a block.
Static reason
One or more suspicious static signals were detected.
Trigger
A host calls createBrowseRuntime; the telemetry client is then created and logs are enabled unless OTEL_SDK_DISABLED is set.
Impact
Runtime log data may be sent to a telemetry endpoint without disclosure in the package README; the endpoint and full data scope could not be established from this package source.
Mechanism
Runtime log attributes and exception details are forwarded to the @agimon-ai/po-logsink logger. The telemetry endpoint is resolved outside the inspected source.
AI rationale
The runtime sends telemetry logs by default, but the README does not disclose this behavior and the telemetry endpoint is not established in the inspected package source. The behavior requires explicit runtime creation, and I found no evidence of install-time collection or credential theft, so this warrants a warning rather than a block.
Evidence
dist/index.cjs
Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Creating the browser runtime constructs a telemetry client.
- Runtime logs are enabled unless OTEL_SDK_DISABLED is set.
- The telemetry client forwards log attributes and exception details to its logger.
Evidence against
- The telemetry behavior is triggered by an explicit runtime factory call, not package import.
- The package describes browser automation and MCP server functionality consistent with its process and network operations.
- No install lifecycle scripts are declared.
