pintumcp@1.2.2

Agent Alerts MCP — desktop notifications with sound for AI coding agents

AI Security Review

scanned 14d ago · by lpm-firewall-ai

The automatic setup changes detected AI tool configurations, but the written entry launches this package's own MCP server. This is first-party extension setup and supports a warning rather than a block.

Static reason

One or more suspicious static signals were detected.

Trigger

npm postinstall runs the install command.

Impact

Detected tools are configured to launch pintumcp as an MCP server.

Mechanism

The install command detects supported AI tools and writes a pintumcp server entry containing this package's Python executable and server path.

AI rationale

Evidence

package.jsoninstall.jsbin/pintumcp.jslib/configure.js

Decision evidence

public snapshot

AI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The postinstall hook automatically runs the package's install command.
Install configures pintumcp as an MCP server in detected AI tool configurations.
The configured entry launches this package's own Python server; this is first-party extension setup.

Evidence against

The source shows configuration writes limited to a pintumcp MCP entry in detected tool configs.
A source search found no HTTP references in the Python directory.
