pintumcp@1.2.24
Agent Alerts MCP — desktop notifications with sound for AI coding agents
AI Security Review
scanned 11d ago · by lpm-firewall-aiThe postinstall hook automatically configures pintumcp-owned integrations in detected agent locations. This is a guarded first-party agent setup risk, but the inspected source does not establish malicious behavior or a concrete attack.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm installation invokes postinstall, which runs the CLI install command.
Impact
Agent configuration is modified to enable pintumcp alerts; no credential theft, unrelated control hijack, or malicious payload execution was established.
Mechanism
The CLI copies its OpenCode plugin and adds pintumcp notification hooks to Claude Code settings when those configuration locations exist.
AI rationale
The postinstall hook automatically configures pintumcp-owned integrations in detected agent locations. This is a guarded first-party agent setup risk, but the inspected source does not establish malicious behavior or a concrete attack.
Evidence
package.jsoninstall.jsbin/pintumcp.jslib/hooks.js~/.config/opencode/plugins/pintumcp.js~/.claude/settings.json
Decision evidence
public snapshotAI called this Suspicious at 92.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs install.js from its postinstall hook.
- install.js launches the CLI with the install command during postinstall.
- The install command copies a package-owned OpenCode plugin when that configuration directory exists.
- When Claude settings exist, the install command adds hooks; the hook helper writes five event handlers into settings.json.
Evidence against
- The integration setup is for pintumcp's own alerts plugin and hooks, and checks for the relevant configuration directories.
- The hook helper preserves unrelated hook entries; no credential collection or network transmission was identified in the inspected behavior.
