AI Security Review
scanned 3mo ago · by lpm-firewall-aiNo concrete malicious chain was found, but explicit user-command mutation of an AI-agent configuration is a capability that warrants a warning under the review policy.
Static reason
One or more suspicious static signals were detected.
Trigger
User runs `mcp-scraper-cli agent install claude --apply` with an API key.
Impact
Adds or replaces the `mcp-scraper` MCP entry in the invoking user's Claude Code configuration.
Mechanism
Scoped Claude MCP registration and hosted API requests.
AI rationale
No concrete malicious chain was found, but explicit user-command mutation of an AI-agent configuration is a capability that warrants a warning under the review policy.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Explicit `agent install ... --apply` can modify Claude Code's user-scope MCP registration.
- The apply path runs local `claude mcp get/remove/add` commands, replacing only the `mcp-scraper` entry.
- CLI sends a supplied MCP Scraper API key to its configured hosted API endpoint.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- Agent mutation requires the user to invoke the CLI command and pass `--apply`.
- Configuration is scoped to the package's own named MCP server; no foreign or broad agent-config write was found.
- No confirmed credential harvesting, hidden exfiltration, remote payload execution, or destructive behavior was found.
