@agimon-ai/po-browse-tool@0.0.0-alpha.82
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 flagged process and network operations support browser automation and use the Chrome for Testing feed. However, the default MCP logger initializes runtime telemetry unless disabled, and the inspected README does not disclose it; this warrants a warning rather than a block.
Static reason
One or more suspicious static signals were detected.
Trigger
Creating the MCP server with its default logger and handling server events or tool calls; telemetry can be disabled with OTEL_SDK_DISABLED.
Impact
Server and tool event metadata, and logged errors, may leave the process. The inspected call path records tool names and timestamps; it does not show tool arguments being logged.
Mechanism
The default logger delegates logs to the package's Node telemetry sink. Its destination is resolved from OTEL environment settings or Agimon configuration; the package source does not hard-code that telemetry host.
AI rationale
The flagged process and network operations support browser automation and use the Chrome for Testing feed. However, the default MCP logger initializes runtime telemetry unless disabled, and the inspected README does not disclose it; this warrants a warning rather than a block.
Evidence

Network endpoints2
googlechromelabs.github.ioOTLP endpoint resolved from OTEL_* or Agimon telemetry configuration; hostname is not hard-coded
Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest describes a Playwright browser automation MCP server.
- The telemetry class enables logs unless OTEL_SDK_DISABLED is set and initializes the Node telemetry sink.
- The default MCP logger uses the browse-tool-mcp service name and sends log levels through that telemetry class.
- The server logs tool names and timestamps when handling tool calls; no evidence found that it logs the supplied arguments.
- The Chrome for Testing metadata feed is hosted at googlechromelabs.github.io, consistent with the browser tooling purpose.
Evidence against
- The manifest exposes library entry points and declares no bin command; its purpose is browser automation.
- The process inspection and execution behavior supports browser lifecycle and automation tasks.
- Telemetry destinations are resolved from environment or Agimon configuration rather than a hard-coded unrelated collector.
