ChatGPT ​

ChatGPT now supports MCP through its Connectors feature. You add an MCP server URL in your settings, and ChatGPT automatically discovers and uses its tools during conversations. With GPT-4o, o1, and o3's reasoning capabilities, MCP tools become part of the world's most widely used AI assistant.

The Most Widely Used AI, Now with MCP ​

ChatGPT needs no introduction — it's the AI assistant used by millions. MCP Connectors extend it with your own tools. Instead of being limited to web browsing, DALL·E, and code interpreter, ChatGPT can now query your databases, check your monitoring systems, and interact with your internal APIs.

The o-series reasoning models (o1, o3) are particularly effective with MCP because they plan multi-step approaches. When asked to analyze a complex situation, they might call multiple MCP tools in sequence, reason over results, and produce a comprehensive answer.

What MCP adds to ChatGPT:

  • Custom tool access — query your own systems from the ChatGPT interface
  • Connectors — add MCP servers through a simple settings panel
  • Model selection — GPT-4o for fast tasks, o1/o3 for deep reasoning with MCP tools
  • Cross-platform — tools available on web, mobile, and desktop apps
  • Memory — ChatGPT remembers tool configurations across sessions
  • Custom GPTs — build GPTs that include specific MCP tool access

Quick Setup ​
