Upgrade to mcp-scraper 0.98.0 or newer. Older releases include obsolete local execution code; see the packaged README for hosted-client migration.
MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 3mo ago · by lpm-firewall-aiNo malicious installation or covert execution chain is present, but the package intentionally grants broad authenticated browser and connected-account capabilities to AI-agent clients. This is a real dangerous-capability risk warranting a warning rather than a block.
Static reason
One or more suspicious static signals were detected.
Trigger
User runs the stdio server or explicitly invokes MCP/browser/connected-account tools.
Impact
Can operate on user-authorized hosted browser profiles and connected-account data; capability is high-risk if delegated to an untrusted agent.
Mechanism
API-key-authenticated requests to hosted browser, memory, and service-control endpoints.
AI rationale
No malicious installation or covert execution chain is present, but the package intentionally grants broad authenticated browser and connected-account capabilities to AI-agent clients. This is a real dangerous-capability risk warranting a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- dist/chunk-2K4RCBYY.js exposes hosted authenticated browser-profile and connected-account tools.
- dist/bin/mcp-stdio-server.js sends the supplied API key to mcpscraper.dev MCP endpoints.
- dist/bin/mcp-scraper-cli.js can explicitly upsert its Claude user-scope MCP entry via --apply.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- Agent configuration mutation requires explicit `agent install claude --apply`; default behavior prints instructions.
- Browser-profile flow states users sign in through a returned watch URL and existing local cookies are not imported.
- No source evidence of stealth execution, arbitrary credential harvesting, payload download/execution, or destructive behavior.
