Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- MCP tool explicitly saves fresh logins for ChatGPT, Claude, Reddit, and other sites into hosted profiles.
- Browser-agent requests send its API key and inputs to the configured service endpoint.
- Saved hosted profiles can be reopened for authenticated browser sessions and extensions can be imported.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- The credential-bearing browser flow is an explicitly registered user-invoked MCP tool; it does not import existing local cookies.
- Default endpoint is the package-aligned https://mcpscraper.dev, not a hidden third-party gateway.
