@agimon-ai/po-browse-tool@0.0.0-alpha.84
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 process execution is consistent with the package’s stated purpose. However, runtime telemetry is enabled by default, forwards log attributes and exception details, and is not disclosed in the inspected README, so the package is suspicious rather than clean.
Static reason
One or more suspicious static signals were detected.
Trigger
When the package’s telemetry/logger initializes during runtime; logging can be disabled with OTEL_SDK_DISABLED.
Impact
Runtime data may be sent to the configured or resolved telemetry service without disclosure in the inspected package documentation.
Mechanism
The code creates a telemetry client, resolves log and trace endpoints from environment settings or a telemetry dependency, and forwards log attributes and exception details.
AI rationale
The browser process execution is consistent with the package’s stated purpose. However, runtime telemetry is enabled by default, forwards log attributes and exception details, and is not disclosed in the inspected README, so the package is suspicious rather than clean.
Evidence
dist/index.cjs
Decision evidence
public snapshotAI called this Suspicious at 79.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Runtime logging is enabled unless OTEL_SDK_DISABLED disables it.
- The package initializes a telemetry client that resolves log and trace endpoints from environment settings or its telemetry dependency.
- When logging is enabled, log records include attributes and exception details.
- The package manifest has no install, preinstall, or postinstall hook.
Evidence against
- The package is a Playwright browser automation MCP server, and its Chrome process launch matches that purpose.
- The manifest’s scripts are build, development, test, typecheck, lint, and formatting commands.
