What is N3XT MCP?

N3XT MCP connects your AI assistant (Cursor, Claude Desktop, or another MCP-compatible client) to your N3XT account. Once connected, your assistant can view your N3XT data - such as payments, wallets, and account activity - and perform supported actions on your behalf.

How to install

After you sign in and authenticate, open the Connect your client page. There you’ll find:

  • Install links for supported editors and CLIs

  • Copy-paste JSON config for manual setup

  • Per-client docs with step-by-step instructions

  • Pick your client, follow its guide, and point it at this site’s MCP URL.

How it works

Three steps from zero to a connected assistant:

1. Sign in to N3XT MCP

Use your organization’s B2B login. This is the same identity you use across N3XT.

2. Add this MCP server to your client

Point your app at this site’s MCP URL. Your client uses OAuth discovery to find where to send you for approval.

3. Approve the connection

The first time your assistant talks to N3XT, your browser opens a consent screen. Approve access to finish setup.

You can revoke any connected client anytime under Connected apps.

Permissions & security

  • Read and write tools enabled - perform supported actions and manage your account directly through MCP

  • OAuth scopes - mcp:read, mcp:write (or your specific write scopes), plus standard OIDC scopes

  • Your account, your control - access is tied to your N3XT login; revoke clients under Connected apps anytime

Troubleshooting

  • Browser didn’t open for consent?

Check that your MCP client supports OAuth discovery, and that pop-ups aren’t blocked.

  • Connection failed after sign-in?

Confirm you used the MCP URL and JSON from the Connect your client page for your specific editor or CLI.

  • Want to disconnect?

Go to Connected apps in N3XT and revoke the client.

  • Anything else?
