⚠ Under reviewBraintrust observability provider for Mastra - includes tracing and future observability features
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe inspected package implements Braintrust tracing export and has no lifecycle hook or confirmed attack behavior. Its required braintrust dependency source was unavailable, so dependency behavior remains unresolved and a clean verdict is not supported.
Static reason
No blocking static signals were detected.
Trigger
Importing the package loads its runtime dependencies; tracing and score export occur when the observability exporter receives events.
Impact
No package-level attack impact was established; unresolved dependency behavior prevents a clean determination.
Mechanism
The package uses the Braintrust SDK to initialize a logger and submit tracing and score data. Inspection of the SDK dependency could not be completed.
AI rationale
The inspected package implements Braintrust tracing export and has no lifecycle hook or confirmed attack behavior. Its required braintrust dependency source was unavailable, so dependency behavior remains unresolved and a clean verdict is not supported.

Decision evidence
public snapshotAI called this Manual Review at 87.0% confidence as Unknown with medium false-positive risk.
AI review observations
- The manifest declares braintrust as a runtime dependency, and the published entrypoint imports it.
- The declared braintrust dependency source was unavailable for inspection, so its runtime behavior remains unresolved.
- The inspected code initializes and uses a Braintrust logger to export tracing and score events; no concrete attack behavior was identified in the available source.
Evidence against
- The manifest contains no lifecycle scripts; its listed scripts are build, test, lint, and examples.
- The inspected Mastra observability exporter handles tracing events and returns early when disabled.
