Connect WasenderAPI to AI agents and automation tools using the Model Context Protocol. This remote MCP server exposes WhatsApp session management, messaging, contacts, and groups as callable tools for Claude Code, OpenCode, n8n, and other MCP-compatible platforms. Requires a paid plan and Personal Access Token for authentication.

WasenderAPI MCP Integration Guide

Add the WasenderAPI MCP to your favorite tools (Claude Code/Desktop/CLI, OpenCode, or n8n) using your Personal Access Token.

MCP integration is only available on paid plans. This feature is not available on trial accounts.

Replace YOUR_PERSONAL_ACCESS_TOKEN with the token from your WasenderAPI account settings. Keep it secret.

Claude Code / Desktop / CLI

Ensure the Claude CLI is installed and logged in.
Register the MCP using your token:

claude mcp add --transport http wasenderapi https://wasenderapi.com/mcp \
  --header "Authorization: Bearer YOUR_PERSONAL_ACCESS_TOKEN"

Verify it appears with claude mcp list and start a new Claude Code session; the WasenderAPI tools will be available.

OpenCode

Open your OpenCode config (defaults to ~/.config/opencode/config.json).
Paste the configuration snippet below under the "mcp" key:

{
  "mcp": {
    "WasenderAPI": {
      "type": "remote",
      "url": "https://wasenderapi.com/mcp",
      "enabled": true,
      "headers": {
        "Authorization": "Bearer YOUR_PERSONAL_ACCESS_TOKEN"
      }
    }
  },
  "$schema": "https://opencode.ai/config.json"
}

Restart or reload OpenCode. The WasenderAPI MCP will show up as WasenderAPI.

If you already have other MCP entries, just add the "WasenderAPI" block alongside them.

n8n (MCP Tool Node)

Requires n8n v2.0 or later. n8n ships an MCP Tool node that can call external MCP servers.

Install/upgrade to n8n v2.0+ and enable the LangChain Tool MCP node (see n8n MCP docs).
Create a new workflow and add the LangChain Tool MCP node.
Configure MCP endpoint: https://wasenderapi.com/mcp.
Add header Authorization: Bearer YOUR_PERSONAL_ACCESS_TOKEN.
Pick the desired tool (e.g., send-message, contacts, groups) and provide the arguments in JSON.
Execute the node; n8n will call the MCP tool and return the response.

Ensure your WasenderAPI session is connected and the token is valid before running.
