Connect via MCP

The Whatnot Seller API has a hosted MCP server. Connect an MCP-compatible client to let it call the Seller API directly, using your own API token.

Server URL:

https://mcp.whatnot.com

When you connect, your client will prompt you to authenticate before it can make requests on your behalf.

Set up your client

Run the following command to add the Whatnot Seller API MCP server to Claude Code:

claude mcp add --transport http --client-id bb1bf1ca-0452-4737-ad8f-81175f1601b8 --callback-port 8080 whatnot https://mcp.whatnot.com

After you add the server, authenticate with:

claude /mcp

Add the following configuration to ~/.cursor/mcp.json (or .cursor/mcp.json in your project) to add the Whatnot Seller API MCP server:

{
  "mcpServers": {
    "whatnot-seller-api": {
      "url": "https://mcp.whatnot.com",
      "auth": {
        "CLIENT_ID": "bb1bf1ca-0452-4737-ad8f-81175f1601b8"
      }
    }
  }
}

For more information, see Cursor's MCP documentation.

Open VS Code and open the Command Palette (Cmd+Shift+P on macOS, Ctrl+Shift+P on Windows/Linux).
Search for and select MCP: Open User Configuration.
Add this configuration to your user-level mcp.json file:

{
  "servers": {
    "whatnot-seller-api": {
      "type": "http",
      "url": "https://mcp.whatnot.com",
      "oauth": {
        "clientId": "bb1bf1ca-0452-4737-ad8f-81175f1601b8"
      }
    }
  }
}

Save your configuration and restart VS Code.

See the VS Code MCP documentation for more information.

{
  "mcpServers": {
    "whatnot-seller-api": {

      "oauthClientId": "bb1bf1ca-0452-4737-ad8f-81175f1601b8"
    }
