SendKuy

SendKuy MCP server

Give AI assistants and agents a way to reach people: send WhatsApp, SMS and email, verify OTP codes and run campaigns through your SendKuy account.

Use it while you build an integration ("send a test OTP to my number", "why is my webhook failing?"), or as the notification step of an agent that runs on its own: an on-call alert, a daily revenue summary, an order update per customer.

Get a key

Create an API key at app.sendkuy.com/user/api. Give it account:read plus the scopes of the tools you want, and nothing more. The server lists only the tools your key can use, so a key with read scopes never sees a tool that sends.

Install

Claude Code:

claude mcp add --transport stdio --env SENDKUY_API_KEY=sk_live_YOUR_API_KEY sendkuy -- npx -y @sendkuy/mcp

Cursor (.cursor/mcp.json), Windsurf and Claude Desktop:

{
  "mcpServers": {
    "sendkuy": {
      "command": "npx",
      "args": ["-y", "@sendkuy/mcp"],
      "env": { "SENDKUY_API_KEY": "sk_live_YOUR_API_KEY" }
    }
  }
}

VS Code (.vscode/mcp.json):

{
  "inputs": [
    {
      "type": "promptString",
      "id": "sendkuy-key",
      "description": "SendKuy API key",
      "password": true
    }
  ],
  "servers": {
    "sendkuy": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@sendkuy/mcp"],
      "env": { "SENDKUY_API_KEY": "${input:sendkuy-key}" }
    }
  }
}

Claude Desktop can also install sendkuy-mcp.mcpb from the latest release with one click.

Tools that send really send and spend credit. They take an optional dedupe_key: an agent that repeats a step with the same key gets the first answer back instead of sending twice.

Examples

• On-call alert. "When the health check fails, WhatsApp the on-call group with the service name and the error." The agent sends to the group's grp_ id with dedupe_key set to the incident id.
• Daily revenue summary. "Every evening, send each branch manager their own numbers." One sendkuy_send_batch call, a different body per manager.
• Debugging an integration. "Which WhatsApp messages failed in the last hour, and why?" sendkuy_list_messages, then sendkuy_list_webhook_deliveries.

Configuration

Variable
SENDKUY_API_KEY	Your API key. Without it, or when the key is invalid or SendKuy can't be reached at start-up, the server still starts and lists its tools, and every call answers with the reason until you fix it and restart the client.
SENDKUY_BASE_URL	Only for a proxy or a mock server in tests. Defaults to https://app.sendkuy.com/api/v1.
