tina4-nodejs@3.13.122
Tina4 for Node.js/TypeScript - native TypeScript conventions and shared Tina4 contracts
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is a guarded, first-party agent-extension setup rather than concrete malware or exfiltration. It remains a publish warning because it automatically mutates a consumer project's AI-agent discovery surface.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Starting a Tina4 application with TINA4_DEBUG enabled.
Impact
Adds a localhost AI-agent extension entry and may update the project's ignore file; no external credential send was confirmed.
Mechanism
Automatic project-local MCP discovery configuration.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The active runtime bundle invokes MCP discovery when the debug-only DevAdmin surface is enabled.
- The discovery writer creates a project-local MCP configuration that advertises the framework's localhost dev endpoint.
- The manifest has no preinstall, install, or postinstall hook; its lifecycle scripts only run the build.
Evidence against
- The generated endpoint is localhost rather than an external host.
- The source inspected contains no credential transmission to an external endpoint.

Credential Exfiltration
Source appears to send environment or credential material to an external endpoint.
