@grum-os/cli@0.3.3
Keep code on your design contract: a local drift check, review requests, Cursor hooks and an MCP server.
AI Security Review
scanned 1mo ago · by lpm-firewall-aiSource inspection supports a warning for explicit CLI agent configuration and subsequent unpinned package execution. The absence of install hooks and the package-aligned reporting flow do not support blocking as malicious.
Static reason
One or more suspicious static signals were detected.
Trigger
Running grum init cursor or grum setup; interactive setup requests consent, while noninteractive setup can configure an existing Cursor directory.
Impact
Changes agent behavior and enables later package execution or resolution without a fresh installation prompt.
Mechanism
Writes Grum hooks, an MCP server, and an always-applied rule; generated MCP and pre-commit commands use unpinned npx --yes.
AI rationale
Source inspection supports a warning for explicit CLI agent configuration and subsequent unpinned package execution. The absence of install hooks and the package-aligned reporting flow do not support blocking as malicious.

Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest exposes grum.mjs as the CLI and contains no lifecycle scripts or runtime self-dependency.
- CLI setup writes repository Cursor hooks, MCP configuration, and a rule that guides agent behavior.
- Interactive setup offers a consent prompt; noninteractive setup also configures Cursor when its directory exists.
- Generated MCP and pre-commit commands use unpinned npx --yes, allowing later package resolution without another installation prompt.
- The flagged location only identifies the Grum rule path; configuration mutation occurs elsewhere in the CLI.
- Saved credentials are bound to their API origin; the flagged command-output transmission reports the Git commit with design-check results.
Evidence against
- No automatic npm installation mutation or concrete malicious attack was identified.
- Configuration helpers preserve unrelated hooks and MCP servers, and support removing Grum entries.
