Huly MCP: feature-complete MCP server for Huly integration
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package sends runtime usage telemetry to PostHog by default, and the inspected README does not disclose it. The captured fields appear limited to operational metadata, and users can opt out, so this warrants a warning rather than a malicious verdict.
Static reason
No blocking static signals were detected.
Trigger
Starting the MCP server with telemetry enabled, which is the default.
Impact
PostHog receives session identifiers and operational usage metadata. No prompt or tool content was identified in the inspected telemetry fields.
Mechanism
The application creates a PostHog client and captures session and tool activity events; HULY_MCP_TELEMETRY=0 or DO_NOT_TRACK disables it.
AI rationale
The package sends runtime usage telemetry to PostHog by default, and the inspected README does not disclose it. The captured fields appear limited to operational metadata, and users can opt out, so this warrants a warning rather than a malicious verdict.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- Runtime telemetry is sent to PostHog at https://us.i.posthog.com.
- MCP telemetry is enabled by default unless HULY_MCP_TELEMETRY=0 or DO_NOT_TRACK disables it.
- Telemetry records session and tool activity metadata.
Evidence against
- The inspected telemetry fields include session IDs, package and runtime metadata, tool names, status, duration, and byte counts; no prompt or tool content was identified.
- Users can disable telemetry with HULY_MCP_TELEMETRY=0 or DO_NOT_TRACK.
