Claude Code Commands Reference

Jatin Bansal@blog:~/notes$ open claude-code-commands

A comprehensive guide to essential Claude Code CLI commands for efficient AI-powered development workflows, with special focus on Docker MCP Gateway integration.

Docker MCP Gateway Management

I prefer to use MCP servers through the Docker MCP Gateway. It provides a unified way for managing MCP servers across different tools like Cursor, Claude, and other AI clients without manual configuration for each tool.

Key Benefits:

Centralized MCP server management
Container-based isolation and security
Unified configuration across clients
Built-in secret management
Server catalog discovery

Gateway Security Features

Container Isolation: Each MCP server runs in isolated Docker containers
Signature Verification: Verify provenance of MCP container images
Secret Scanning: Block secrets in inbound/outbound payloads
Network Restrictions: Controlled network access for servers
Resource Limits: CPU and memory constraints per server
