MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 2mo ago · by lpm-firewall-aiSource inspection found an explicit user-command agent configuration mutation and optional profile persistence, not malicious automatic behavior. Warn for the dangerous capability without publishing a block.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The user runs mcp-scraper-cli agent install claude --apply, or enables browser profile saving during a browser session.
Impact
The named Claude MCP configuration can be replaced, and opted-in browser-session state can be saved to the selected profile.
Mechanism
Explicit CLI-driven MCP registration and optional browser-profile persistence.
AI rationale
Source inspection found an explicit user-command agent configuration mutation and optional profile persistence, not malicious automatic behavior. Warn for the dangerous capability without publishing a block.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The explicit agent-install command offers an --apply option that upserts a user-scope Claude MCP server.
- With --apply, the CLI runs Claude commands to remove and add only the named mcp-scraper server.
- An explicit browser-profile option can persist cookies and browser storage after a session.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- The agent configuration mutation requires a user to invoke agent install with --apply and is limited to the mcp-scraper entry.
- The default hosted endpoint is the package's own mcpscraper.dev domain; no fixed unofficial credential gateway was confirmed.
- No source evidence showed automatic credential harvesting, remote code loading, or destructive behavior.
