Braze (MCP)

🚀 Quickstart

Connect to the Braze MCP server with Nango and call MCP tools in minutes. Braze MCP uses OAuth 2.0 with dynamic client registration, so no app registration is required.

Create the integration

In Nango (free signup), go to Integrations → Configure New Integration → Braze (MCP).

Authorize Braze

Go to Connections → Add Test Connection → Authorize, choose your region, then log in to your Braze account. Later, you’ll let your users do the same directly from your app.

Call the Braze MCP API

Make your first MCP request (initialize handshake). Replace the placeholders below with your Environment API key, integration ID, and connection ID:

cURL
Node

curl "https://api.nango.dev/proxy/mcp" \
  -X POST \
  -H "Authorization: Bearer <NANGO-API-KEY>" \
  -H "Provider-Config-Key: <INTEGRATION-ID>" \
  -H "Connection-Id: <CONNECTION-ID>" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "initialize",
    "params": {
        "protocolVersion": "2024-11-05",
        "capabilities": {},
        "clientInfo": {
            "name": "nango-client",
            "version": "1.0.0"
        }
    }
}'

Install Nango’s backend SDK with npm i @nangohq/node. Then run:

import { Nango } from '@nangohq/node';

const nango = new Nango({ apiKey: '<NANGO-API-KEY>' });

const res = await nango.post({
    endpoint: '/mcp',
    providerConfigKey: '<INTEGRATION-ID>',
    connectionId: '<CONNECTION-ID>',
    body: {
        jsonrpc: '2.0',
        id: 1,
        method: 'initialize',
        params: {
            protocolVersion: '2024-11-05',
            capabilities: {},
            clientInfo: {
                name: 'nango-client',
                version: '1.0.0'
            }
        }
    }
});

console.log(res.data);

✅ You’re connected! Check the Logs tab in Nango to inspect requests.

📚 Braze (MCP) guides

Nango uses dynamic client registration with Braze’s MCP OAuth server, so you do not register an MCP application. Before your users can connect, check the following in Braze:

Paid account: the Braze MCP server is not available on free trial accounts.

Admin approval: a company admin must turn on MCP OAuth access and approve Nango’s redirect URI (https://api.nango.dev/oauth/callback, or your own custom callback URL) in Settings → Admin Settings → External Connections.

Permissions: the user needs the Use MCP Server permission. The MCP tools act with the user’s own dashboard permissions, so a user scoped to a team rather than a whole workspace may not be able to use every tool.

No IP allowlisting: companies that use dashboard IP allowlisting cannot use the Braze MCP server.

In the integration’s settings in Nango, add the scopes Braze’s MCP server asks for: mcp:tools, mcp:resources and mcp:operator. What the agent can do is the intersection of the granted scopes and the user’s own dashboard permissions: it can never do more than the user can.

When they connect, users choose Braze’s US endpoint (mcp.braze.com) or EU endpoint (mcp.braze.eu). Braze recommends the EU endpoint for EU customers; non-EU customers can use either. See How do I link my account?.
