pintumcp@1.2.25
Agent Alerts MCP — desktop notifications with sound for AI coding agents
AI Security Review
scanned 11d ago · by lpm-firewall-aiThe postinstall trigger performs automatic agent configuration and plugin setup, so this merits a warning under the agent extension lifecycle policy. The reviewed code shows package-owned notification integrations and no confirmed malicious attack behavior.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Installing the npm package triggers its postinstall script.
Impact
Agent configuration and plugin state can be changed without a separate setup command; no concrete malicious payload or data theft was established.
Mechanism
The script runs the CLI install command, which detects coding tools, writes MCP configuration, adds Claude Code hooks, and installs the OpenCode plugin when applicable.
AI rationale
The postinstall trigger performs automatic agent configuration and plugin setup, so this merits a warning under the agent extension lifecycle policy. The reviewed code shows package-owned notification integrations and no confirmed malicious attack behavior.
Evidence
package.jsoninstall.jsbin/pintumcp.jslib/configure.jslib/hooks.js
Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs install.js during postinstall.
- install.js automatically invokes the package CLI's install command.
- The install command detects coding tools and writes a pintumcp MCP entry to their configurations.
- If Claude Code is present, setup adds pintumcp hooks for multiple agent events.
- Setup also copies a package-owned OpenCode alerts plugin into the user's plugin directory.
Evidence against
- The inspected integrations configure this package's own notification server and hooks; no credential collection or network exfiltration behavior was identified in the reviewed paths.
