@agimon-ai/po-browse-tool@0.0.0-alpha.89
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 package’s browser execution and Chrome download behavior fit its stated purpose, and it has no install hook. However, runtime logging is enabled by default without a located disclosure, while the inspected source does not reveal enough about the telemetry payload or endpoint to establish a more severe finding.
Static reason
One or more suspicious static signals were detected.
Trigger
The telemetry manager is constructed during runtime initialization; logging is enabled unless OTEL_SDK_DISABLED is set.
Impact
Runtime data may be sent without a clear disclosure or user opt-out path; the available source does not show sensitive data collection.
Mechanism
The package wires OpenTelemetry logging through its telemetry dependency. The inspected source does not expose the full payload or resolved default endpoint.
AI rationale
The package’s browser execution and Chrome download behavior fit its stated purpose, and it has no install hook. However, runtime logging is enabled by default without a located disclosure, while the inspected source does not reveal enough about the telemetry payload or endpoint to establish a more severe finding.
Evidence
dist/index.cjspackage.json$HOME/.cache/chrome-for-testing
Network endpoints2
googlechromelabs.github.io/chrome-for-testing/known-good-versions-with-downloads.jsonOpenTelemetry endpoints resolved from environment/configuration; exact default host is not established in the inspected source.
Decision evidence
public snapshotAI called this Suspicious at 72.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package exports its main CommonJS and ESM entry points from dist/index.cjs and dist/index.mjs.
- The manifest declares build, test, typecheck and lint scripts but no install lifecycle scripts.
- The runtime telemetry manager enables logs unless OTEL_SDK_DISABLED is set; the package README search found no telemetry disclosure.
- Chrome for Testing metadata is fetched from the official googlechromelabs.github.io release feed as part of browser setup.
Evidence against
- The package is described as an MCP server for Playwright browser automation, which accounts for browser process execution and browser-related network activity.
- The stdio server starts through an explicit start() call, and the manifest has no install hooks.
- The inspected source does not establish that telemetry sends credentials, file contents, prompts, code or tool output.
