post-engineer-mcp@1.33.0
Post Engineer MCP Server for AI pair programming and agentic workflows
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package’s runtime telemetry is documented and disabled unless POSTHOG_API_KEY is configured; the tracked event contains only the tool name. The default HTTP listener is stdio, and the inspected API credential flow targets the configured service API.
Static reason
One or more suspicious static signals were detected.
Trigger
A tool invocation, with PostHog telemetry enabled by setting POSTHOG_API_KEY.
Impact
No unauthorized collection or action was identified in the inspected paths.
Mechanism
Sends a tool-name event to PostHog using the configured host, defaulting to eu.i.posthog.com. The application API key is sent to the configured Post Engineer API base URL for API requests.
AI rationale
The package’s runtime telemetry is documented and disabled unless POSTHOG_API_KEY is configured; the tracked event contains only the tool name. The default HTTP listener is stdio, and the inspected API credential flow targets the configured service API.

Decision evidence
public snapshotAI called this Clean at 95.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest points the executable to dist/index.js; its prepublishOnly hook only builds the package.
- README documents optional PostHog telemetry and says it is disabled without POSTHOG_API_KEY.
- Analytics reads POSTHOG_API_KEY and returns without initializing PostHog when it is absent.
- Tracked events contain the tool name and use a fixed package distinct ID; the wrapper does not pass tool arguments.
- The server starts HTTP transport only when explicitly given --http-transport; otherwise it uses stdio.
- The API client sends its configured API key to the configured Post Engineer API base URL.

Copied Package Dependency Bridge
Package metadata claims a different repository identity while copied source loads a runtime dependency bridge.
