MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is not malicious under the stated boundary because configuration mutation is explicit, scoped to the package entry, and absent from npm lifecycle hooks. It merits a warning for agent-extension and credential-routing capability.
Static reason
One or more suspicious static signals were detected.
Trigger
User runs `mcp-scraper-cli agent install claude --apply` or starts the MCP stdio server with an API key.
Impact
User-approved agent configuration can grant the package MCP capabilities and send its supplied package API key to the configured service.
Mechanism
Explicit MCP registration and authenticated hosted MCP forwarding.
AI rationale
This is not malicious under the stated boundary because configuration mutation is explicit, scoped to the package entry, and absent from npm lifecycle hooks. It merits a warning for agent-extension and credential-routing capability.

Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Explicit `agent install ... --apply` can replace the user's Claude MCP entry.
- The stdio MCP server sends its configured API key to its configured hosted endpoint.
Evidence against
- package.json has no install, preinstall, or postinstall lifecycle hook.
- Agent configuration mutation requires the explicit `agent install <host> --apply` command.
- The mutation targets only the named `mcp-scraper` Claude user-scope entry and includes rollback handling.
- No source-confirmed stealth persistence, arbitrary remote payload execution, or credential harvesting was found.
