MCP client setup

Use streamable HTTP against https://api.greentick.ai/mcp. Send the API key as Authorization: Bearer gt_live_… on every request. A bare key, without the Bearer prefix, is rejected. Do not put the key in the URL, a chat, a screenshot, or a committed file. The key is created in Developer. It is shown once and belongs to the WhatsApp Business account you had selected.

Connect https://api.greentick.ai/mcp. The /mcp address on this docs site only searches the documentation. It cannot send WhatsApp messages.

Claude Desktop

Edit the Claude Desktop config and restart Claude.

macOS
Windows

The file is ~/Library/Application Support/Claude/claude_desktop_config.json.

{
  "mcpServers": {
    "greentick": {
      "type": "http",
      "url": "https://api.greentick.ai/mcp",
      "headers": {
        "Authorization": "Bearer gt_live_YOUR_API_KEY"
      }
    }
  }
}

The file is %APPDATA%\Claude\claude_desktop_config.json.

{
  "mcpServers": {
    "greentick": {
      "type": "http",
      "url": "https://api.greentick.ai/mcp",
      "headers": {
        "Authorization": "Bearer gt_live_YOUR_API_KEY"
      }
    }
  }
}

Claude Code

Add the server from the terminal, then start a new session:

claude mcp add --transport http greentick https://api.greentick.ai/mcp --header "Authorization: Bearer gt_live_YOUR_API_KEY"

Cursor

Open Settings → MCP and add a server, or edit .cursor/mcp.json in the project (or the global MCP file):

{
  "mcpServers": {
    "greentick": {
      "url": "https://api.greentick.ai/mcp",
      "headers": {
        "Authorization": "Bearer gt_live_YOUR_API_KEY"
      }
    }
  }
}

VS Code

Create .vscode/mcp.json:

{
  "servers": {
    "greentick": {
      "type": "http",
      "url": "https://api.greentick.ai/mcp",
      "headers": {
        "Authorization": "Bearer gt_live_YOUR_API_KEY"
      }
    }
  }
}

Other clients

Any client that speaks streamable HTTP can use the same address and header:

URL: https://api.greentick.ai/mcp
Transport: streamable HTTP
Header: Authorization: Bearer gt_live_YOUR_API_KEY

Confirm the connection

Ask the assistant to call get_api_key. A working key returns the key name, the key prefix, and the account timeZone. An empty timezone means the account timezone is not set yet. The assistant uses that timezone when you schedule a template without naming a zone. Then try a read that does not send anything: List approved templates starts with list_templates. The send itself still waits until you ask.
