pintumcp@1.2.6
Agent Alerts MCP — desktop notifications with sound for AI coding agents
AI Security Review
scanned 14d ago · by lpm-firewall-aiThe package’s automatic postinstall path mutates foreign AI-agent configurations and installs command integrations, while also establishing login startup. This meets the policy for blocking unconsented install-time AI control-surface mutation.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm install invokes the package postinstall hook.
Impact
This changes AI-agent configuration and establishes package behavior that runs during agent events and at user login.
Mechanism
The hook runs the CLI install command, which detects tools, writes their configuration, installs agent integrations, and configures tray startup.
Policy narrative
During package installation, postinstall launches the CLI installer. That command detects installed AI coding tools and writes MCP configuration, adds Claude Code command hooks and an OpenCode plugin, and creates tray startup entries. These changes affect agent behavior and login persistence without a separate user-invoked setup command.
AI rationale
The package’s automatic postinstall path mutates foreign AI-agent configurations and installs command integrations, while also establishing login startup. This meets the policy for blocking unconsented install-time AI control-surface mutation.
Evidence

Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 96.0% confidence with low false-positive risk.
Evidence for policy risk
- package.json runs install.js from an automatic postinstall hook.
- install.js invokes the CLI install command during postinstall.
- The install command detects AI tools and configures each detected tool, then adds an OpenCode plugin and Claude Code hooks when those directories exist.
- The indicated Claude settings location is modified by adding command hooks for three events.
- The configuration helper writes the package’s MCP server entry into detected tools’ configuration.
- The install path also creates tray startup entries that run at login.
