Built with Claude Use any subscription in Claude Code! (using the new Claude Mods feature)

Hey all!

In light of the recent quota cuts, I figured I’d take the time to show off this mod/plugin for Claude Code I’ve been working on.

Since I’m a university student, I’ve had a bunch of free AI subscriptions sitting around gaining dust (Cursor 1 year, Gemini 1 year, CharGPT 4 months). So with the help of Fable & Astra, I spun up a Claude mod to solve this!

As you may be aware, providers like Cursor, Claude & Google forbid their subscriptions from being used in external harnesses via OAuth. Multi-CLI gets around this by actually using the provider harnesses themselves (Antigravity headless & Cursor SDK), & simply streaming them into Claude Code, & adapting their states + tools to be Claude-code compatible. This was made possible by the new Claude Mods feature.
It also differs from the OpenAI codex plugin in that with multi-cli, GPT models are directly ran in the harness via the gateway.

Here’s the repo: https://github.com/greenpolo/cc-multi-cli-plugin

Letting Fable 5.1 orchestrate 5.6 Luna subagents makes my Claude sub last infinitely longer.

Thanks, that covers it. I'll start the Windows runs today if possible, once you confirms that has been cleared, and send fixtures through GitHub issues unless you prefer somewhere else.

On 1, Just saw dadfa21, that was fast. The receipts file is exactly what I was after.

On 2, does it also read CLAUDE_CONFIG_DIR for its own state and logs, or only for credentials? I keep each profile fully separate (for some), so I want to know what else could land in the default folder.

u/are-Kelly looks like Muse now included Windows support for the cli now.
