MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is a user-invoked agent-extension capability with credentialed network access, so it warrants a warning. The source does not establish malicious behavior or an unconsented npm lifecycle attack.
Static reason
One or more suspicious static signals were detected.
Trigger
The user runs mcp-scraper-cli agent install claude --apply or another API-using CLI command.
Impact
A user can intentionally grant the package future MCP execution and persist browser profile state; no unconsented install-time mutation was found.
Mechanism
Explicit MCP client registration and authenticated vendor API requests.
AI rationale
This is a user-invoked agent-extension capability with credentialed network access, so it warrants a warning. The source does not establish malicious behavior or an unconsented npm lifecycle attack.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The explicit agent install command can replace the user's Claude Code mcp-scraper registration.
- The CLI reads an API key from the environment or a dedicated key file and sends it to the configured service when invoked.
- The CLI can enable persistence of browser cookies and storage for a named profile.
Evidence against
- package.json exposes binaries but contains no npm preinstall, install, or postinstall hook.
- Agent configuration mutation requires the user to run the agent install command with --apply.
- The default service endpoint is the package's own mcpscraper.dev domain; no covert exfiltration chain was confirmed.
