Add Quicknode MCP to Cursor

One-click install via deeplink:

Add Quicknode MCP to Cursor

cursor://anysphere.cursor-deeplink/mcp/install?name=quicknode&config=eyJ0eXBlIjoiaHR0cCIsInVybCI6Imh0dHBzOi8vbWNwLnF1aWNrbm9kZS5jb20vbWNwIn0=

Cursor will show an approval dialog, then write the server into your ~/.cursor/mcp.json.

Manual install

Edit ~/.cursor/mcp.json (global) or .cursor/mcp.json (project) and add:

{
  "mcpServers": {
    "quicknode": {
      "type": "http",
      "url": "https://mcp.quicknode.com/mcp"
    }
  }
}

No auth block needed. The Quicknode MCP server uses OAuth 2.1 with Dynamic Client Registration (RFC 7591). Cursor will register itself automatically against https://mcp.quicknode.com/register and walk you through OAuth in your browser on first connect.

What you get

Manage your blockchain infrastructure from your AI assistant: endpoints, rate limits, security, metrics, logs, and billing. See the plugin README for capabilities.

Troubleshooting

  • First connection hangs: confirm your browser opened the OAuth consent page. If your popup blocker swallowed it, copy the URL from Cursor's logs.
  • "Insufficient scope" errors: try removing the server and re-adding it. The DCR client may have been registered with stale scopes.
  • Cursor keeps re-registering: known upstream issue (cursor forum). Doesn't affect functionality.

Requirements
