pintumcp@1.2.18
Agent Alerts MCP — desktop notifications with sound for AI coding agents
AI Security Review
scanned 9d ago · by lpm-firewall-aiThe lifecycle hook automatically configures package-owned agent integrations without a separate consent step. This is an agent extension lifecycle risk; the inspected sources do not establish a concrete malicious attack.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package through npm, which runs its postinstall hook.
Impact
Agent configuration changes and later hook activity may be unexpected; the inspected evidence supports a warning for automatic first-party extension setup, not a confirmed attack.
Mechanism
The setup writes the package’s MCP entry and installs its OpenCode plugin and Claude Code hooks without an additional consent prompt.
AI rationale
The lifecycle hook automatically configures package-owned agent integrations without a separate consent step. This is an agent extension lifecycle risk; the inspected sources do not establish a concrete malicious attack.
Evidence
package.jsoninstall.jsbin/pintumcp.jslib/configure.jslib/hooks.jspython/hook.py
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 as a postinstall hook.
- install.js launches the CLI install command during postinstall.
- The CLI defaults to install and configures detected tools, then installs its OpenCode plugin and Claude Code hooks when their directories exist.
- The specified Claude settings location calls addHooks; the hook helper registers package-owned commands for five Claude Code events.
- The Claude hook uses prompt text, limited to 80 characters, in its status message.
Evidence against
- The integrations configure this package’s own MCP entry and package-owned plugin or hooks; inspected code did not establish a write to unrelated agent settings or a remote prompt collector.
