NpmAlternatives costs $0.01 per call on xpay. No subscription, no minimums. Pay only for the calls you make. New accounts get $5 in free credits.

Connect the NPM Sentinel MCP endpoint to your client — Claude Code: claude mcp add --transport http npm-sentinel "https://npm-sentinel.mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY"; Cursor/Windsurf/Cline/VS Code: same URL in mcp.json. The agent will see npmAlternatives as a callable tool with the input schema and run it directly. (Unified across all providers: https://mcp.xpay.sh/mcp?key=YOUR_XPAY_KEY, then xpay_run with toolPath npm-sentinel/npmAlternatives.)

Yes — that's exactly what xpay is for. You don't need a NPM Sentinel account or API key. Sign up at xpay.tools (Google or email), get $5 free credit, and run NpmAlternatives immediately. Billing flows through your xpay balance.

NpmAlternatives accepts 2 input parameters: packages, ignoreCache. See the input schema and runnable form on this page for details and to test live.
