Lupin: Run Claude Code with GPT, Kimi, or Local Models Keeping MCP Setup
Ok_Insurance_919 · reddit · 2026-08-09
A developer introduced Lupin, an open-source proxy tool designed to make Claude Code's harness setup (MCPs, skills, .md files) compatible with other LLMs.
- Core Features: Acts as a proxy between Claude Code and other providers. Forwards requests directly for models nively supporting the Anthropic API SDK (like Kimi, DeepSeek, GLM), and translates requests for OpenAI, Gemini, and Ollama.
- Unique Mechanisms: Features a built-in "doctor" to test model performance directly in Claude Code rather than relying on traditional scoring. Supports swapping providers mid-session via command, allowing subagents to run on cheaper models.
- Privacy & UX: Keys are stored in the OS keychain without disk logging, and it offers a terminal TUI dashboard.
The project is open-source on GitHub and can be tested via npx lupin-code@latest init.
