MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is not malware, but it ships high-impact AI-agent browser control and an explicit agent-config mutation path. Warn so users can assess capability grants and authenticated-profile use.
Static reason
One or more suspicious static signals were detected.
Trigger
User runs the MCP server/browser tools or explicitly invokes `mcp-scraper-cli agent install claude --apply`.
Impact
An AI client granted these tools could interact with authenticated web accounts; configuration changes are limited to the package's own Claude entry.
Mechanism
Authenticated browser automation and explicit same-entry MCP registration.
AI rationale
This is not malware, but it ships high-impact AI-agent browser control and an explicit agent-config mutation path. Warn so users can assess capability grants and authenticated-profile use.

Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- dist/bin/mcp-scraper-cli.js: --apply explicitly removes and re-adds its Claude user-scope MCP entry.
- dist/chunk-O63VVCCE.js: browser tools retain user-created authenticated profiles and can navigate, read, click, type, and press keys.
- dist/chunk-O63VVCCE.js: browser tools send authenticated API requests to the configured MCP Scraper service.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- Agent configuration mutation is gated behind the explicit `agent install claude --apply` command and targets only `mcp-scraper`.
- Profile login is an interactive user flow; existing local browser cookies are stated not to be imported.
- No source evidence of secret harvesting, stealth exfiltration, remote code loading, or destructive install-time behavior.
