MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe flagged behavior is explicit, package-aligned MCP/browser functionality rather than stealth execution or exfiltration. Its authenticated-browser and agent-registration capabilities remain materially risky dual-use functionality.
Static reason
One or more suspicious static signals were detected.
Trigger
Explicit MCP use with a configured API key, or explicit `mcp-scraper-cli agent install claude --apply`.
Impact
A configured AI client can operate authenticated browser sessions; this is a powerful dual-use capability but not a confirmed malicious chain.
Mechanism
Hosted MCP browser automation with optional profile persistence and explicit Claude registration.
AI rationale
The flagged behavior is explicit, package-aligned MCP/browser functionality rather than stealth execution or exfiltration. Its authenticated-browser and agent-registration capabilities remain materially risky dual-use functionality.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Explicit CLI --apply replaces the user's Claude user-scope mcp-scraper registration.
- The MCP server reads a local API-key file and sends the key to its configured hosted endpoint.
- Browser tools can open authenticated saved profiles and optionally persist cookies/storage changes.
Evidence against
- package.json has no preinstall, install, postinstall, or prepare hook.
- Agent configuration mutation requires the explicit `agent install ... --apply` command and only supports Claude Code.
- No source-confirmed credential exfiltration, stealth install-time execution, or foreign broad agent-config mutation found.
