Interacting with the MCP Server

The MCP server is designed to be used with clients that understand the Model Context Protocol. Here are ways to interact with it:

VS Code Integration

For use with VS Code, a configuration file is provided in .vscode/mcp.json. VS Code with the appropriate MCP extension can communicate with this server.

AI Assistants

AI assistants like Claude that support MCP can communicate with this server to access Omnisend data and perform operations.

Using with Claude Desktop

To use this MCP server with Claude Desktop:

1. Download and install Claude Desktop from the official website.

2. Make sure you have Node.js installed on your system. You can verify by running:

   node --version
   

   If Node.js is not installed, download it from nodejs.org.

3. Open the Claude menu on your computer and select "Settings..."

4. Click on "Developer" in the left-hand bar of the Settings pane, and then click on "Edit Config"

5. This will open your Claude Desktop configuration file. Replace the file contents with or add the following configuration:

   {
     "mcpServers": {
       "omnisend": {
         "command": "node",
         "args": [
           "/path/to/index.js"
         ],
         "env": {
           "OMNISEND_API_KEY": "your_api_key_here"
         }
       }
     }
   }
   

   Make sure to replace your_api_key_here with your actual Omnisend API key.

6. Save the configuration file and restart Claude Desktop.

7. After restarting, you should see a hammer icon in the bottom right corner of the input box.

8. Click on the hammer icon to see the available Omnisend tools.

9. You can now ask Claude to perform operations such as:

   • "List my recent contacts in Omnisend"
   • "Create a new product in my Omnisend catalog"
   • "Send a customer event to Omnisend"

Custom MCP Clients

You can develop custom clients using the @modelcontextprotocol/sdk library:

import { McpClient } from '@modelcontextprotocol/sdk/client/mcp';
import { ProcessClientTransport } from '@modelcontextprotocol/sdk/client/process';

const transport = new ProcessClientTransport(serverProcess);
const client = new McpClient(transport);

// Connect to the server
await client.connect();

// Execute tools
const result = await client.executeTool("listContacts", { limit: 10 });
