MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 2mo ago · by lpm-firewall-aiNo covert install-time execution, broad agent configuration write, credential harvesting, or undisclosed exfiltration was found in the inspected entrypoints. The explicit user-command agent configuration mutation merits a warning under the firewall policy.
Static reason
One or more suspicious static signals were detected.
Trigger
A user runs mcp-scraper-cli agent install claude --apply, or starts the MCP server and invokes a hosted tool.
Impact
The package can become an available Claude Code tool and receive the configured package-service API key during its own requests.
Mechanism
Explicit user-scope MCP registration and authenticated hosted tool calls.
AI rationale
No covert install-time execution, broad agent configuration write, credential harvesting, or undisclosed exfiltration was found in the inspected entrypoints. The explicit user-command agent configuration mutation merits a warning under the firewall policy.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- An explicit CLI command can replace the user-scope Claude Code MCP entry named mcp-scraper.
- The replacement runs npx with the package and places the supplied API key in its MCP configuration.
- The stdio server sends its configured API key to the package service when MCP tools are used.
Evidence against
- package.json exposes binaries but declares no npm install lifecycle hook.
- Agent configuration mutation requires the user to invoke agent install with --apply.
- The CLI targets only the mcp-scraper named MCP entry and includes rollback handling.
- The default service endpoint matches the package homepage domain.
