"OpenAI Gym" matching MCP servers:

Multi-provider image generation MCP server that enables image generation from Claude Desktop, Claude Code, or any MCP client using OpenAI, Google Gemini, Stable Diffusion, or a placeholder provider.

An MCP server that acts as a bridge to query multiple OpenAI-compatible LLMs with MCP tool access. Just like rubber duck debugging, explain your problems to various AI "ducks" who can actually research and get different perspectives!

An MCP server that bridges multiple LLMs (OpenAI-compatible APIs and CLI coding agents) for collaborative debugging and diverse AI perspectives.

A universal Worker control plane exposed over MCP that lets a host configure OpenAI-compatible providers and API keys, discover model capabilities, and run, monitor, steer, or cancel Codex worker threads. It ships an app-only control panel so humans manage secrets and worker permissions while models call worker lifecycle tools.
