The Model Context Protocol (MCP) is changing how AI agents interact with external tools. With WasenderAPI MCP Integration, you can now connect AI assistants directly to WhatsApp — enabling them to manage sessions, send messages, handle contacts, and control groups programmatically.

This guide explains how to connect WasenderAPI to popular MCP-compatible platforms like Claude Code, OpenCode, and n8n, and start automating WhatsApp workflows using AI.

What Is Model Context Protocol (MCP)?

Model Context Protocol (MCP) is a standard that allows AI agents to call external tools in a structured, secure, and predictable way. Instead of hard-coding API logic, MCP exposes capabilities as callable tools that AI models can reason about and execute.

With MCP, AI assistants can:

• Discover available tools automatically
• Call APIs using structured inputs and outputs
• Chain multiple actions intelligently
• Operate safely using scoped authentication

Why Use WhatsApp MCP with WasenderAPI?

WasenderAPI provides a remote MCP server that exposes WhatsApp functionality as AI-callable tools. This allows AI agents to control WhatsApp accounts in real time without custom glue code.

• Send and receive WhatsApp messages via AI agents
• Manage multiple WhatsApp sessions
• Control contacts, groups, and channels
• Integrate with automation platforms and AI IDEs

Getting Started with WasenderAPI MCP

To use the WasenderAPI MCP server, you will need a Personal Access Token from your account settings. This token authenticates AI agents securely.

Claude Code / Desktop / CLI Integration

Follow these steps to register WasenderAPI MCP with Claude:

1. Ensure Claude CLI is installed and logged in
2. Register the MCP server using your token
3. Verify the MCP registration

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

After registration, run claude mcp list. The WasenderAPI tools will be available in new Claude sessions automatically.

OpenCode MCP Configuration

OpenCode supports remote MCP servers via its configuration file. Add the WasenderAPI MCP block 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. WasenderAPI MCP will appear as an available tool provider.

n8n MCP Tool Integration

n8n (v2.0+) includes an MCP Tool node that allows workflows to call MCP servers directly.

1. Install or upgrade to n8n v2.0+
2. Enable the LangChain Tool MCP node
3. Create a new workflow
4. Set MCP endpoint to https://wasenderapi.com/mcp
5. Add Authorization header with your token

You can now automate WhatsApp messaging, contacts, and groups using AI-driven workflows.
