Plugins

docker-mcp-toolkit

Integrates Docker Desktop's MCP Toolkit with Claude Code, enabling access to containerized MCP servers managed by Docker Desktop.

Note: This plugin is designed specifically for Docker Desktop's bundled MCP Toolkit. It is not intended for the standalone open-source MCP Gateway. A separate plugin for the OSS version may be provided in the future.

Features:

• Connects Claude Code to Docker Desktop's MCP Gateway
• Provides access to all MCP servers configured via Docker Desktop's MCP Toolkit
• Includes diagnostic commands for troubleshooting gateway issues
• Leverages Docker Desktop's integrated secrets management

Prerequisites:

• Docker Desktop 4.28+ with MCP Toolkit feature enabled
• MCP Gateway accessible via docker mcp command

Usage

Adding the Marketplace

Add this marketplace to Claude Code using one of the following methods:

If your git works with SSH:

/plugin marketplace add docker/claude-plugins

If your git doesn't work with SSH (or prefer HTTPS):

/plugin marketplace add https://github.com/docker/claude-plugins.git

Installing the Plugin

Once the marketplace is added, you can browse available plugins and install the Docker MCP Toolkit plugin:

# Browse all plugins in the docker marketplace
/plugin

# Install the docker-mcp-toolkit plugin
/plugin install docker-mcp-toolkit@docker

Troubleshooting Commands

If the MCP Gateway server isn't working as expected, the plugin provides two diagnostic slash commands to help identify and resolve issues:

• /docker-mcp-toolkit:gateway-status - Quick health check showing enabled servers and available tools
• /docker-mcp-toolkit:gateway-debug - Comprehensive diagnostics to troubleshoot installation and configuration problems

These commands will automatically check your Docker MCP Gateway setup and provide actionable recommendations if problems are found.

Verifying Installation

Once installed, the Docker MCP Gateway will be available as an MCP server in Claude Code. You can verify by:

1. Running /docker-mcp-toolkit:gateway-status to see enabled servers and tool count
2. Checking that MCP tools are available in Claude's toolkit
3. Using Claude to interact with your configured MCP servers

Development

To test changes locally:

1. Make modifications to the plugin files
2. If the marketplace is already added, update it:

   /plugin marketplace update docker
   

3. Reinstall or update the plugin if needed
