AI Security Review
scanned 19d ago · by lpm-firewall-aiThe scanner’s high-risk hints were not supported by the inspected source: the MCP bridge is opt-in and loopback-bound, and the reviewed OAuth flow targets Google endpoints. The runtime location is Mermaid rendering, and the package manifest’s prepare hook runs the build command.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The bridge starts only when its configuration setting and the plugin’s enabled setting are true.
Impact
No unauthorized credential transfer or other concrete attack effect was established.
Mechanism
It writes a workspace MCP entry for a token-protected loopback service and removes its entry during cleanup.
AI rationale
The scanner’s high-risk hints were not supported by the inspected source: the MCP bridge is opt-in and loopback-bound, and the reviewed OAuth flow targets Google endpoints. The runtime location is Mermaid rendering, and the package manifest’s prepare hook runs the build command.

Decision evidence
public snapshotAI called this Clean at 89.0% confidence as Benign with medium false-positive risk.
Evidence for AI clean decision
- The manifest’s prepare hook runs the build command.
- The MCP bridge is off by default and starts only when its setting and the plugin are enabled.
- When enabled, the bridge adds its entry to the workspace MCP configuration and removes that entry during cleanup.
- The bridge listens on loopback, requires a bearer token, and excludes the broad code and agent tools.
- The reviewed OAuth flow uses Google authorization, token, and user-info endpoints; it shows no unrelated credential recipient.
- The specified client runtime location renders Mermaid content using the package’s Mermaid bundle.
Evidence against
- Enabling the MCP bridge exposes eligible DSH tools to MCP clients through a workspace configuration entry; this capability is explicitly disabled by default.
