Overview

This guide walks you through connecting Claude Code CLI to your Gate22 unified MCP server.

​
Prerequisites

Before starting, ensure you have:
  • Claude Code CLI installed on your machine
  • A Gate22 account with at least one configured MCP bundle

​
Step 1: Get Your MCP Bundle URL

  1. Navigate to your MCP Bundles in the Gate22 dashboard
  2. Click on the bundle you want to connect
  3. Copy the MCP URL displayed
Copy MCP Bundle URL

​
Step 2: Add Gate22 Server to Claude Code

Use the claude mcp add command to configure your Gate22 bundle: 
claude mcp add -t http gate22 https://mcp.aci.dev/gateway/mcp?bundle_key=YOUR_BUNDLE_KEY_HERE
Replace YOUR_BUNDLE_KEY_HERE with your actual MCP bundle URL from Step 1.

​
Method 2: Direct Configuration File

Alternatively, you can directly edit the Claude Code configuration file: Location: ~/.claude.json Add this configuration: 
{
  "mcpServers": {
    "gate22": {
      "type": "http",
      "url": "https://mcp.aci.dev/gateway/mcp?bundle_key=YOUR_BUNDLE_KEY_HERE"
    }
  }
}

​
Step 3: Verify Claude Code has access to the Gate22 server

  1. Start Claude Code and use the /mcp command
  2. You should see the newly added Gate22 MCP server

​
Step 4: Test Your Gate22 Bundle

In Claude Code, use the /mcp command - you should see that the Gate22 server is ”✔ connected”: Test the Gate22 tools by asking: 
Search all the available functions in my Gate22 integration
Verify Claude’s response matches your expectation and that it can access the tools from your configured MCP servers.
