Qantara links Claude, Codex, and Gemini in one workflow
Qantara is an MCP server that lets such as Claude Code, Codex, and Gemini hand work to each other or ask each other for feedback. In Claude Code, it provides ask_codex and ask_gemini tools. In Codex or Gemini, it can provide ask_claude.
It works by calling the that are already installed, such as claude -p, codex exec, and gemini -p. That means it can reuse existing logins and instead of requiring separate API keys or extra API billing. Long tasks can run as , so the main tool can keep working and check the result later.
It also includes session management and a loop guard, which is meant to stop the tools from calling each other endlessly.
