# MCP Rubber Duck An MCP (Model Context Protocol) server that acts as a bridge to query multiple LLMs -- both OpenAI-compatible HTTP APIs and CLI coding agents. Just like rubber duck debugging, explain your problems to various AI "ducks" and get different perspectives! <p align="center"> </p> > **Why direct provider integration?** MCP's `sampling` primitive -- a server borrowing the *host's* model -- was deprecated in the [2026-07-28 spec RC](https://github.com/modelcontextprotocol/modelcontextprotocol/pull/2577) in favor of servers integrating directly with LLM provider APIs. Rubber Duck has always worked this way (it brings its own ducks), so it's aligned with where the protocol is heading -- no migration required. ## Features - **Universal OpenAI Compatibility** -- Works with any OpenAI-compatible API endpoint - **CLI Agent Support** -- Use CLI coding agents (Claude Code, Codex, Gemini CLI, Grok, Aider) as ducks - **Multiple Ducks** -- Configure and query multiple LLM providRead full README on GitHub →
