MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 3mo ago · by lpm-firewall-aiNo covert lifecycle execution, credential harvesting, remote payload execution, or unconsented broad agent-control mutation was found. The explicit user-scope MCP setup and retained authenticated-browser capability are nonetheless a real agent-capability risk.
Static reason
One or more suspicious static signals were detected.
Trigger
User runs mcp-scraper-cli agent install claude --apply or invokes browser_profile_connect through the MCP server.
Impact
A compromised or over-privileged MCP client could access capabilities backed by user-authorized saved sessions.
Mechanism
Explicit AI-agent registration plus hosted authenticated-browser profile capability.
AI rationale
No covert lifecycle execution, credential harvesting, remote payload execution, or unconsented broad agent-control mutation was found. The explicit user-scope MCP setup and retained authenticated-browser capability are nonetheless a real agent-capability risk.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Explicit CLI apply path removes and re-adds a user-scope Claude MCP registration.
- MCP exposes a hosted browser-profile feature that saves authenticated site logins for later browser use.
Evidence against
- No preinstall, install, postinstall, or prepare lifecycle hook is declared.
- Agent configuration mutation is gated behind the explicit --apply CLI option, Claude host selection, and an API key.
- The login flow directs the user to sign in fresh; no automatic credential harvesting or unrelated exfiltration was found.
