AI Security Review
scanned 4d ago · by lpm-firewall-aiThe flagged key flow is tied to an OAuth connect submission and validates the submitted key against OneSource’s API. Runtime analytics is disclosed, has an opt-out, and records usage metadata rather than tool argument values.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user submits an API key through the OAuth connect page; analytics events are generated by tool calls.
Impact
No unauthorized credential transfer or other attack behavior was identified.
Mechanism
The key is checked against the configured OneSource API endpoint. Analytics posts tool usage events to the configured analytics endpoint; the package documents that analytics is on by default and can be disabled.
AI rationale
The flagged key flow is tied to an OAuth connect submission and validates the submitted key against OneSource’s API. Runtime analytics is disclosed, has an opt-out, and records usage metadata rather than tool argument values.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The prepare lifecycle script runs only `tsc`.
- The API key check sends the submitted key to the configured OneSource API base URL, defaulting to `https://api.onesource.io`.
- Key validation is handled by the OAuth connect-submit POST route, which is rate-limited.
- The package discloses default-on anonymous usage analytics and explains how to disable it.
- Tool analytics records metadata and input parameter names, not parameter values, and posts events to the configured analytics service.
