Use Nextbridge from Claude Desktop

Connect your Nextbridge account to Claude (or any MCP-compatible client) via a remote Model Context Protocol server. Once configured, Claude can read your balances, place trades with explicit approval, manage price alerts, and answer questions about your portfolio — all without leaving the chat.

Generate an API key

The Nextbridge MCP server authenticates with a USER-scoped API key. Each key is tied to your account and can be revoked at any time. Admin tools (treasury, dispute resolution) live on a separate endpoint and require an ADMIN-scoped key.

  1. Log in and go to Settings → Security → API keys.
  2. Click Create API key, name it (e.g. "Claude Desktop").
  3. Copy the key — it starts with nbx_user_. You won't see it again; store it somewhere safe.
  4. Paste it into the box below — your config snippet updates as you type.
Never paste an API key into a chat with Claude. Only put it in your client's config file — the client sends it in the Authorization header without ever showing it to the model.

Add Nextbridge to your AI client

Nextbridge runs as a remote MCP server — there's nothing to install on your machine. Your client connects over HTTPS using mcp-remote, a tiny adapter that ships with npx. Requires Node.js 20+.

Pasted only in your browser; never sent to Nextbridge from this page.

Restart and try it

Fully quit and reopen Claude Desktop (Cmd+Q on macOS, not just close the window — MCP servers only load on cold start). You should see a small 🔌 icon showing that nextbridge is connected. Try any of these:

What's in my Nextbridge portfolio? Summarize my biggest position.Try in Claude →
Show me BTC and ETH prices and decide if either looks oversold.Try in Claude →
I want to put 10% of my USDC balance into SOL — what would that look like?Try in Claude →
List my open P2P trades and any disputes I should resolve.Try in Claude →
You're set.
Trades and withdrawals initiated by Claude pass through the same safeguards as the web UI: balance checks, daily limits, and 2FA when required. The MCP server enforces per-key rate limits (120 read calls/min, 30 write calls/min) and audits every call.
