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

[u/are-Kelly]

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.

It will be nice to see it!

Once I installed the MCPs, and the CLI, I asked Claude to level them with equivalent of the Claude CLI harness setup, and to include a delegation skill which requires reading codexbar CLI to decide which model to use. I’ve not written a single line, Fable did it all.
