MCP launcher for brokre — local credential broker for Cursor, Claude Code, Kimi Code, Trae, OpenClaw, Hermes Agent, ChatClaw, and other MCP clients

AI Security Review

scanned 15d ago · by lpm-firewall-ai

Source inspection confirms automatic, guarded setup of this package’s own MCP integration in detected agent configurations. Under the agent integration policy, this warrants a warning for first-party extension setup, but the inspected behavior does not establish malicious intent.

Static reason

One or more suspicious static signals were detected.

Trigger

Installing the package with its postinstall script enabled, outside CI and without the opt-out variable.

Impact

The detected tools may automatically make brokre’s MCP server available after installation.

Mechanism

The postinstall launches setup-mcp.js, which detects installed tools and adds the brokre MCP entry to their configuration.

AI rationale

Evidence

package.jsonpostinstall.jssetup-mcp.js

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs postinstall.js automatically during installation.
postinstall.js invokes setup-mcp.js with the inherited environment.
setup-mcp.js detects existing agent configuration, including Codex history and session files.
The setup registers brokre for detected IDEs and writes changed configuration files.
Automatic setup can be skipped with BROKRE_MCP_SKIP_SETUP=1 or in CI.

Evidence against

The installer registers this package’s own MCP server rather than a foreign extension.
The setup writes only when changes are needed and preserves backups of existing configuration files.
