MCP clients quickstart now uses the MCP client grid and has a blurb on authentication modes

---

Note

Updates the MCP client quickstart to streamline connection instructions and clarify authentication.

• Replaces per-client setup Tabs with MCPClientGrid for client-specific connection guidance
• Documents MCP Gateway authentication modes (Arcade Auth and Arcade Headers) and when to use each
• Minor copy tweak for gateway slug guidance and removes redundant per-client links in Next Steps

@wdawson asked for your review mostly to check that my authentication mode blurb is not saying something stupid!

This works! Another note for Arcade Auth is that anyone who belongs to your project can access the gateway. If you need to share the gateway outside of your project or outside of Arcade, you need to use header auth today.
