MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 2mo ago · by lpm-firewall-aiNo lifecycle hook or covert install-time behavior was found. The explicit agent configuration and authenticated browser-control features remain a dangerous capability that warrants a warning.
Static reason
One or more suspicious static signals were detected.
Trigger
A user runs the MCP server or explicitly invokes mcp-scraper-cli agent install with --apply.
Impact
A configured AI client can access the package's broad browser automation capabilities; no unconsented install-time action or external credential theft was confirmed.
Mechanism
Authenticated remote MCP and browser-session control.
AI rationale
No lifecycle hook or covert install-time behavior was found. The explicit agent configuration and authenticated browser-control features remain a dangerous capability that warrants a warning.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The explicit agent-install command replaces a user-scope Claude MCP entry with this package.
- The stdio client sends its configured API key to the configured service endpoint.
- The bundled service can control authenticated browser sessions and capture prompts and results.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- The agent configuration change requires the user to invoke the CLI with --apply.
- Browser-session routes require authentication and enforce ownership of the session.
