SendApp MCP

What it is

The SendApp MCP server exposes SendApp's features as tools for AI assistants compatible with the Model Context Protocol. It's a JSON-RPC 2.0 endpoint over HTTP: your MCP client (Claude Desktop, n8n and others) calls the tools and SendApp performs the operations on your account.

Endpoint and authentication

• Endpoint: https://app.sendapp.ai/api/mcp
• Authentication: pass your SendApp API key in one of these two ways:
  • in the X-API-Key header (recommended);
  • or, if your MCP client does not allow custom headers (e.g. Claude's web connector), in the URL: https://app.sendapp.ai/api/mcp?apikey=YOUR_API_KEY.
  Your plan must include API access.

Available tools

• get_account — profile, plan and usage.
• get_tokens — lists the account tokens.
• get_contacts — lists/searches contacts (by text or tag).
• create_contact — creates or updates a contact.
• delete_contact — deletes a contact by id.
• get_whatsapp_templates — approved WhatsApp templates.
• create_whatsapp_template — creates a WhatsApp template and sends it to Meta for approval.
• update_whatsapp_template — edits an existing template and resends it to Meta.
• delete_whatsapp_template — deletes a template.
• send_whatsapp_meta / send_whatsapp_web / send_sms — sending messages.
• create_campaign_draft — creates a campaign as a draft (does not send).
• launch_campaign — sends an existing draft campaign.

How to connect it

1. Retrieve your API key (you'll find it in the API documentation).
2. Configure your MCP client with the URL https://app.sendapp.ai/api/mcp and the X-API-Key header with your key; alternatively, if your client does not support headers, pass the key in the URL as https://app.sendapp.ai/api/mcp?apikey=YOUR_API_KEY.
3. Start a conversation: your AI will see the SendApp tools and will be able to use them.

Example (JSON-RPC)

List of available tools:
