MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe source establishes a potentially high-impact agent capability with persistent browser profiles and remote API calls, so warning is appropriate. It does not establish malicious install-time behavior, exfiltration, or a covert persistence chain.
Static reason
One or more suspicious static signals were detected.
Trigger
A user configures and runs the MCP server, invokes browser tools, or explicitly runs the CLI apply command.
Impact
A configured agent gains broad remote browser capability and may preserve an authenticated browser profile; this needs user trust but is not proven malicious.
Mechanism
API-key-authenticated remote MCP calls with optional persistent hosted browser profiles.
AI rationale
The source establishes a potentially high-impact agent capability with persistent browser profiles and remote API calls, so warning is appropriate. It does not establish malicious install-time behavior, exfiltration, or a covert persistence chain.

Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package exposes an MCP stdio executable.
- The stdio server sends API-key-authenticated tool requests to its configured remote service and registers browser-agent tools.
- The bundled server can create hosted browser sessions with a named profile and persist profile changes.
- An explicit CLI apply action removes and adds the package's Claude MCP entry.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- The default service host is package-aligned: mcpscraper.dev.
- The Claude configuration change is behind an explicit CLI action, not install-time execution.
- No source evidence showed automatic credential harvesting or exfiltration.
