Cursor SDK package for Mastra
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe manifest has no install lifecycle hook, and the runtime’s environment-key use is part of caller-invoked Cursor SDK setup. The inspected source shows no concrete attack behavior.
Static reason
No blocking static signals were detected.
Trigger
A caller invokes the exported agent’s runtime methods.
Impact
No unauthorized credential transfer, install-time action, or other concrete attack was established.
Mechanism
The wrapper resolves an SDK agent using caller options and, when needed, the Cursor API key from the environment, then sends the supplied prompt through the SDK.
AI rationale
The manifest has no install lifecycle hook, and the runtime’s environment-key use is part of caller-invoked Cursor SDK setup. The inspected source shows no concrete attack behavior.
Evidence
package.jsondist/index.js
Decision evidence
public snapshotAI called this Clean at 97.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest points to the `dist` runtime and lists build, test, and lint scripts without install lifecycle hooks.
- Runtime agent creation occurs when `generate` is called, and the wrapper sends the supplied prompt through the Cursor SDK.
- The API key comes from caller options or `CURSOR_API_KEY` and is passed into Cursor SDK creation options.
