MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 3mo ago · by lpm-firewall-aiNo concrete malicious chain was found, but the package exposes high-impact authenticated browser automation to MCP tool callers. Its explicit Claude registration mutation is user-command gated and scoped to its own entry.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user installs/configures the MCP server, authenticates a hosted profile, then invokes browser or workflow tools.
Impact
An authorized but over-privileged agent/tool caller could act through a saved third-party web session.
Mechanism
Authenticated hosted-browser automation and explicit Claude MCP registration.
AI rationale
No concrete malicious chain was found, but the package exposes high-impact authenticated browser automation to MCP tool callers. Its explicit Claude registration mutation is user-command gated and scoped to its own entry.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- dist/chunk-BP2IUIAH.js exposes hosted browser sessions using saved authenticated profiles.
- browser_profile_connect directs users to sign in to arbitrary domains including ChatGPT and Claude, then reuses that profile.
- query_fanout_workflow can submit a real message in the logged-in account when given a prompt.
- dist/bin/mcp-scraper-cli.js can alter the Claude user-scope MCP registration, but only after explicit agent install claude --apply.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- Agent configuration mutation is explicitly gated by --apply and limited to its mcp-scraper entry.
- Profile setup states existing cookies are not imported and the user signs in fresh.
- Network calls use configured API credentials and package-aligned mcpscraper.dev endpoints; no covert exfiltration was found.
