@agimon-ai/po-browse-tool@0.0.0-alpha.78
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 package appears to provide legitimate browser automation, but its runtime enables telemetry by default and can attach workflow or agent context to logs. The collector is dynamically resolved and the source does not establish exactly what is transmitted, so this is suspicious rather than clearly malicious.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Creation of the browser runtime when the server starts.
Impact
Workflow or agent context may be sent to a telemetry collector without clear package-level disclosure; the package source does not establish the resolved collector host.
Mechanism
The runtime creates a telemetry delegate with the process environment and detected workspace root. Logs are enabled unless OTEL_SDK_DISABLED is set, and log records can include workflow and agent context attributes. The collector endpoint is resolved dynamically or supplied through OTLP environment settings.
AI rationale
The package appears to provide legitimate browser automation, but its runtime enables telemetry by default and can attach workflow or agent context to logs. The collector is dynamically resolved and the source does not establish exactly what is transmitted, so this is suspicious rather than clearly malicious.
Evidence
dist/index.cjs
Network endpoints1
OTLP endpoint from OTEL_EXPORTER_OTLP_* settings or the @agimon-ai/po-logsink resolver (host not literal in package source)
Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Runtime construction creates telemetry with the detected workspace root and process environment.
- Runtime logs are enabled unless OTEL_SDK_DISABLED is set; telemetry setup also passes enableLogs: true and enableTraces: true to the telemetry delegate.
- The telemetry context supports agent and workflow fields, including workflow.workspace, job names, and workflow IDs.
- Log records are sent through the telemetry logger with context and attributes attached.
Evidence against
- The manifest describes a Playwright browser automation MCP server, which explains its browser, process, and network capabilities.
- Trace export can use OTLP endpoints configured through environment variables; the package does not contain a fixed telemetry collector hostname.
- The source provides an OTEL_SDK_DISABLED opt-out.
