Claude Code

docker mcp client connect claude-code --profile dev-tools --global

Codex

docker mcp client connect codex --profile <profile-id>

Notes

Needs Docker Desktop 4.59 or later with MCP Toolkit turned on under Beta features, or the CLI plugin built from source. Create a profile and add catalog servers first (docker mcp profile create); dev-tools is the README's example profile. docker mcp client connect supports claude-code and codex among other clients. Docker Desktop keeps the servers' secrets and OAuth tokens. Each catalog server still needs its own account or key if its service requires one.
