MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is not malware by the inspected source: there is no install hook or confirmed covert exfiltration. Its authenticated-browser automation and AI response interception remain a dangerous capability that warrants a warning.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A configured MCP or API user opens an authenticated browser profile and invokes the fanout workflow.
Impact
An authorized caller or compromised MCP client could read AI-chat responses and cause actions in the logged-in browser session.
Mechanism
CDP response capture plus browser prompt automation in saved profiles.
AI rationale
This is not malware by the inspected source: there is no install hook or confirmed covert exfiltration. Its authenticated-browser automation and AI response interception remain a dangerous capability that warrants a warning.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- It can attach a Chrome DevTools session and collect matching AI-chat response bodies.
- A workflow can submit a prompt in the active browser session, wait for its response, and parse the captured content.
- The browser onboarding route creates a saved, user-owned profile for a chosen login domain.
Evidence against
- package.json contains no install, preinstall, or postinstall lifecycle hook.
- The sensitive browser functions are reached through authenticated runtime routes and explicit MCP/browser use, not package installation.
- No source evidence showed secret exfiltration, hidden remote payload loading, or mutation of local AI-agent configuration.
