Quick start

1. Get an API key

1. Sign up at instantkom.app

2. Settings → API Keys → create a new key

3. Copy the key (format: ik_live_...)

2. Configure your MCP client

Add to your Claude Code / Claude Desktop config:

Claude Code: project-local .mcp.json or ~/.config/claude/claude_desktop_config.json Claude Desktop (macOS): ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "instantkom": {
      "command": "npx",
      "args": ["-y", "@instantkom/mcp-server"],
      "env": {
        "INSTANTKOM_API_KEY": "ik_live_..."
      }
    }
  }
}

3. Restart your client

Claude will now see the instantkom MCP server with all available tools.

Configuration

Tool overview

Tools are grouped by resource type. Each REST endpoint at api.instantkom.app/api-docs has a corresponding MCP tool.

Examples

Once configured, you can prompt Claude in natural language:

> Send a newsletter to all "Premium" segment contacts.

⏺ I'll create the newsletter via WhatsApp.
   ⤷ create_broadcast(channel: "whatsapp", segment: "premium")
   ↳ 247 recipients · sending now.

⏺ Done. Sent to 247 Premium contacts. Show live analytics?

Development

git clone https://github.com/instantKOM/mcp-server.git
cd mcp-server
npm install
npm run build
INSTANTKOM_API_KEY=ik_live_... node dist/index.public.js

To wire up your local build with Claude Code instead of npm:

{
  "mcpServers": {
    "instantkom": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-server/dist/index.public.js"],
      "env": {
        "INSTANTKOM_API_KEY": "ik_live_..."
      }
    }
  }
}

Security

• API keys are passed as Bearer tokens. Treat them as secrets.

• All API calls go over HTTPS to api.instantkom.app by default.

• The MCP server runs locally on your machine — no instantKOM data passes through any third-party host.

• Audit log of every tool call is recorded server-side in your instantKOM account.
