The official OpenAI MCP server lets you use OpenAI's full model suite as tools within any MCP-compatible AI client — including Claude, Cursor, and Windsurf.
Features:
- Chat completions with any GPT model (GPT-4o, o1, o3-mini)
- DALL-E 3 image generation from text prompts
- Whisper audio transcription
- Text embeddings for semantic search
- Moderation API for content safety checks
- Function/tool calling passthrough
- Streaming response support
- Batch API for high-volume requests
Cross-model use cases:
- Use Claude as orchestrator while delegating image generation to DALL-E
- Use GPT-4o for tasks where it outperforms other models
- Use Whisper for voice transcription within a Claude workflow
- Generate embeddings for RAG pipelines directly from MCP
Full OpenAI API compatibility — all models and endpoints supported.
