MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 2mo ago · by lpm-firewall-aiSource confirms explicit user-command AI-agent configuration mutation and high-privilege MCP capabilities, which warrants a warning under the stated policy. It does not establish malicious install-time behavior or a concrete covert attack chain.
Static reason
One or more suspicious static signals were detected.
Trigger
User runs `mcp-scraper-cli agent install claude --apply` or invokes relevant MCP tools.
Impact
Adds a package-controlled MCP server to Claude Code and can process user-authorized account/session data.
Mechanism
Explicit Claude MCP registration plus hosted browser and connected-service capabilities.
AI rationale
Source confirms explicit user-command AI-agent configuration mutation and high-privilege MCP capabilities, which warrants a warning under the stated policy. It does not establish malicious install-time behavior or a concrete covert attack chain.

Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Explicit `agent install ... --apply` invokes Claude CLI to replace the user-scope mcp-scraper MCP entry.
- The MCP server exposes hosted authenticated-browser profile setup and connected-service data export capabilities.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- Agent configuration mutation is reachable only through an explicit CLI subcommand and `--apply`, requires an API key, and is limited to its own named server.
- No fixed credential-redirection gateway or covert install-time exfiltration was confirmed in inspected source.
