MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 2mo ago · by lpm-firewall-aiNo malicious install hook, concealed exfiltration, or autonomous persistence was found. The explicit user-command Claude MCP mutation is a meaningful agent-extension risk and warrants a warning.
Static reason
One or more suspicious static signals were detected.
Trigger
The user runs mcp-scraper-cli agent install claude --apply, then starts the configured MCP server.
Impact
A user-approved agent configuration gains this package's broad advertised MCP capabilities and access to its API key.
Mechanism
Explicit Claude MCP registration and authenticated hosted tool access.
AI rationale
No malicious install hook, concealed exfiltration, or autonomous persistence was found. The explicit user-command Claude MCP mutation is a meaningful agent-extension risk and warrants a warning.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- An explicit CLI option can replace the user's Claude Code MCP entry with this package.
- The MCP server reads an API key from environment variables or a package-specific home-directory file.
- The configured server registers browser, scheduling, and memory tools.
Evidence against
- package.json has no install lifecycle hook.
- The Claude configuration change requires the user to run the CLI with --apply.
- The default network service is the package's documented mcpscraper.dev endpoint.
- No source evidence shows hidden credential exfiltration, remote code loading, or automatic persistence.
