Tina4 for Node.js/TypeScript - native TypeScript conventions and shared Tina4 contracts
AI Security Review
scanned 2mo ago · by lpm-firewall-aiNo automatic install-time credential theft or foreign control-surface mutation was found. The guarded dashboard still provides persistent first-party MCP configuration, which warrants a warning under the extension lifecycle policy.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user or authorized local dashboard request posts to /__dev/api/grounding/token.
Impact
The project gains persistent configuration for the Tina4 MCP service; exposure or misuse of that token depends on subsequent service use.
Mechanism
Persisting MCP configuration into the current project's .env file.
AI rationale
No automatic install-time credential theft or foreign control-surface mutation was found. The guarded dashboard still provides persistent first-party MCP configuration, which warrants a warning under the extension lifecycle policy.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The development dashboard accepts a submitted MCP token and persists it in the current project's .env file.
- The persisted token is paired with a default first-party MCP endpoint.
- Dev-admin mutations are guarded by same-origin and loopback-or-token checks.
Evidence against
- The token write is activated by a dashboard request, not an npm install lifecycle hook.
- The source contains explicit refusal checks for cross-origin and unauthorized non-loopback mutation requests.
- The AI client defaults provider credentials to the corresponding OpenAI or Anthropic service endpoints; no hidden recipient was found.
