cc-multi-cli-plugin
A Claude Code plugin that brings other providers' models and coding tools, ChatGPT through Codex, Cursor, OpenCode Zen, Antigravity and Grok, into a single Claude Code session, each keeping its own login.
A user switches models in place with a model-picker command and can pick a reasoning effort with a separate command, or delegate to named background workers that report progress, elapsed time and support cancellation. OpenAI and OpenCode Zen route through Claude Code's own tools, while Cursor, Antigravity and Grok instead run their own native SDK or CLI tools within the session.
Saved sessions can be resumed while each provider's credentials and native state stay separate from one another, and Claude Code's own permission mode and explicit tool restrictions continue to govern what any provider's dispatch is allowed to do. It installs as a set of separate plugins, one per provider, through Claude Code's plugin marketplace, with each provider plugin pulling in a shared core plugin. It is licensed Apache-2.0 and written in TypeScript.
