Wix CRM MCP server

Wix CRM provides comprehensive customer relationship management capabilities. With this MCP server, AI agents can manage contacts, member accounts, organize customers with labels, track activities, and keep your customer database clean and organized. Use this if you need to automate lead management, centralize customer information, or manage member registrations.

Setting up an MCP server

This article covers the standard steps for creating an MCP server in AI Gateway and connecting it to an AI client. The steps are the same for every integration — application-specific details (API credentials, OAuth endpoints, and scopes) are covered in the individual application pages.

Before you begin

You'll need:

• Access to AI Gateway with permission to create MCP servers
• API credentials for the application you're connecting (see the relevant application page for what to collect)

Create an MCP server

Find the API in the catalog

1. Sign in to AI Gateway and select MCP Servers from the left navigation.
2. Select New MCP Server.
3. Search for the application you want to connect, then select it from the catalog.

Configure the server

1. Enter a Name for your server — something descriptive that identifies both the application and its purpose (for example, "Zendesk Support — Prod").
2. Enter a Description so your team knows what the server is for.
3. Set the Timeout value. 30 seconds works for most APIs; increase to 60 seconds for APIs that return large payloads.
4. Toggle Production mode on if this server will be used in a live workflow.
5. Select Next.

Configure authentication

Enter the authentication details for the application. This varies by service — see the Authentication section of the relevant application page for the specific credentials, OAuth URLs, and scopes to use.

Configure security

1. Set any Rate limits appropriate for your use case and the API's own limits.
2. Enable Logging if you want AI Gateway to record requests and responses for auditing.
3. Select Next.

Deploy

Review the summary, then select Deploy. AI Gateway provisions the server and provides a server URL you'll use when configuring your AI client.

Connect to an AI client

Once your server is deployed, you'll need to add it to the AI client your team uses. Select your client for setup instructions:

• Claude Desktop
• Claude Code
• Cursor
• VS Code
• Windsurf

Tips

• You can create multiple MCP servers for the same application — for example, a read-only server for reporting agents and a read-write server for automation workflows.
• If you're unsure which OAuth scopes to request, start with the minimum read-only set and add write scopes only when needed. Most application pages include scope recommendations.
• You can edit a server's name, description, timeout, and security settings after deployment without redeploying.

Authentication

OAuth 2.0 is used for authentication with the Wix CRM API. Create a Wix app in the Wix Developer Dashboard and configure the OAuth settings with the following endpoints:

• Authorization URL: https://www.wix.com/installer/install
• Token URL: https://www.wixapis.com/oauth2/token
• Redirect URI: https://auth.aigateway.cequence.ai/v1/outbound/oauth/callback

The following required headers must be included in API requests:

• Authorization: Bearer {access_token}
• wix-site-id: {site_id}

Available tools

The available tools enable AI agents to manage all aspects of customer relationships: contact creation and updates, member account management, labeling and segmentation, and activity tracking.

Tips

Check for duplicate email addresses before importing or bulk-updating contacts to avoid creating duplicate records.

Use labels strategically to segment your audience — for example, VIP customers, leads, or contacts acquired from specific campaigns.

Always include an email address when creating or updating contacts, as it is the primary identifier for communications and merge operations.

Log activities regularly (notes, calls, meetings) to maintain a complete interaction timeline that helps with follow-up and customer service.

Verify that you are keeping the record with the most complete information before confirming the merge when merging duplicate contacts.
