I built an MCP server that lets Claude Code delegate tasks to Codex, Copilot, Cursor & Gemini — on quota you already pay for
I made an open-source MCP server that turns Codex, GitHub Copilot, Cursor, and Google's Antigravity (Gemini) CLIs into sub-agents you can call from inside Claude Code — using the subscriptions you already pay for, no new API keys.
I kept switching between coding assistants mid-task — Claude Code for most things, but wanting Gemini for a quick cheap answer, Codex for heavier reasoning, or an image generated without reaching for a separate tool. So I built agent-intern, a single MCP server that exposes all four as clean tools:
\- Antigravity (Gemini 3.5 Flash) — fast, cheap tool-calling, and the only backend that can generate images (you get the saved file back).
\- Codex (OpenAI) — strong reasoner with a real, OS-enforced sandbox for actual repo edits.
\- Copilot (GitHub) — agentic coding on your Copilot plan.
\- Cursor — the widest model menu (GPT / Claude / Grok / Composer via one flag).
What you get:
\- Delegate to a different model family mid-task without leaving your terminal.
\- agent_swarm — fan N tasks out in parallel across all four backends at once.
\- A live "watch" window to see the sub-agent work step by step.
\- Zero new auth — it piggybacks the logins you already did. Each backend is independent; install one or all four.
It runs the official CLIs under your own logins — no private APIs, no token scraping. One honest caveat: these run as autonomous agents, so use trusted prompts on trusted content (Codex's sandbox is the only hard boundary — full security notes in the README).

Happy to answer questions or take feedback — it started as a scratch-my-own-itch thing and grew from there.
