pintumcp@1.2.11
Agent Alerts MCP — desktop notifications with sound for AI coding agents
AI Security Review
scanned 12d ago · by lpm-firewall-aiThe postinstall automatically configures package-owned AI tool integrations and adds event hooks, establishing a guarded agent extension lifecycle risk. The inspected behavior supports a warning, not a confirmed attack.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package through npm, which runs its postinstall script.
Impact
These integrations run automatically in supported tools after setup, and setup also creates tray-at-login persistence.
Mechanism
The setup copies an OpenCode plugin and adds Claude Code command hooks to user configuration; the hooks invoke the package’s Python hook script.
AI rationale
The postinstall automatically configures package-owned AI tool integrations and adds event hooks, establishing a guarded agent extension lifecycle risk. The inspected behavior supports a warning, not a confirmed attack.
Evidence
package.jsonbin/pintumcp.jslib/hooks.js~/.config/opencode/plugins/pintumcp.js~/.claude/settings.json
Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs install.js during postinstall.
- The install command adds Claude Code hooks and copies the package’s OpenCode plugin into user configuration.
- The hooks register package-owned notification commands for five Claude Code events.
Evidence against
- The setup targets named integrations and invokes the package’s own hook and plugin files.
- The inspected setup shows no credential forwarding or unrelated remote payload execution.
