AI Security Review
scanned 4d ago · by lpm-firewall-aiNo malicious credential flow was found: the flagged key path validates a user-submitted key against the configured OneSource API. Runtime usage analytics are enabled by default, but the setup tool discloses them as optional and provides an opt-out; the recorded events contain metadata and input field names rather than values.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Analytics runs during MCP server use; API-key validation occurs after a user submits the connect form.
Impact
The analytics reports tool and network details and input field names, not input values; no credential exfiltration or unrelated account action was found.
Mechanism
The package sends tool-use metadata to its analytics endpoint and validates a submitted API key against the configured OneSource API.
AI rationale
No malicious credential flow was found: the flagged key path validates a user-submitted key against the configured OneSource API. Runtime usage analytics are enabled by default, but the setup tool discloses them as optional and provides an opt-out; the recorded events contain metadata and input field names rather than 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 setup tool describes anonymous usage analytics as optional, says it is on by default, and explains how to disable it with ONESOURCE_ANALYTICS=false.
- Tool-call analytics record tool and network metadata, response size, and input field names; the recorded input_params are Object.keys(input), not the input values.
- Analytics events are POSTed to the configured analytics endpoint. The flagged API key is separately validated against the configured OneSource API during the connect-submit flow.
Evidence against
- Analytics is enabled by default, so events may be sent before the user chooses to disable it.
- The connect flow transmits a user-submitted API key to the configured OneSource API for validation.
