MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource inspection found a broad, user-invoked browser automation capability but no lifecycle execution, fixed credential gateway, or concrete exfiltration chain. The static credential-redirection allegation is unsupported by the reviewed code.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
User invokes the MCP/browser-profile workflow and signs into a selected site.
Impact
Can retain a user-authorized browser session for the package's browser-agent features; no unconsented install-time action or credential exfiltration was confirmed.
Mechanism
User-directed browser session and profile management
AI rationale
Source inspection found a broad, user-invoked browser automation capability but no lifecycle execution, fixed credential gateway, or concrete exfiltration chain. The static credential-redirection allegation is unsupported by the reviewed code.

Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with medium false-positive risk.
Evidence for AI clean decision
- The manifest exposes commands through explicit bin entrypoints, including an install-card command.
- Browser sign-in is an explicit runtime workflow: the user logs into the real site and then confirms completion.
Evidence against
- No preinstall, install, or postinstall lifecycle hook is declared.
- The reviewed browser workflow creates a requested remote session/profile; no credential value is read or sent to a fixed unofficial gateway.
- The server restricts crawler requests to validated public URLs and limits redirects.
- The scanner's claimed credential-redirection behavior was not confirmed in the inspected source.
