OpenAI's agent-building API 'Responses API' now supports MCP, making it easier to integrate with other tools & image generation function now available with Responses API

OpenAI's ' Responses API ' is an API with functions such as 'web search,' 'file search,' and 'computer operation,' and is suitable for creating AI agents using OpenAI's AI models. The Responses API now supports the protocol ' Model Context Protocol (MCP) ,' which defines how data is shared between tools, making it possible to access services other than OpenAI via the API. In addition, the Responses API now supports image generation functions.

MCP is a protocol that determines how data is transferred between tools, and tools that support MCP can easily exchange output results. MCP was announced by AI development company Anthropic in November 2024, and at the time of writing, many services such as Cloudflare, Stripe, Shopify, and Zapier support MCP.
With the Responses API now supporting MCP, it is now possible to link OpenAI's AI models with services such as Cloudflare and Stripe. Jeff Weinstein, product director at Stripe, posted a demo video on X (formerly Twitter) showing how the Responses API can be linked with Stripe to automate the generation of payment links.
New as of today: @stripe MCP in @OpenAI Responses API. Just plop in your API key and prompt Stripe in your agentic workflows.

In addition, OpenAI has committed to contributing to the development of MCP itself.
In order to best support the ecosystem and contribute to this developing standard, OpenAI has also joined the steering committee for MCP.

You can now also use the image generation feature via the Responses API. Not only can you instruct the generation of an image via the API, but you can also add detailed instructions step-by-step while viewing the generation process.
Image generation is now available as a tool with the Responses API. Stream previews of images as they're being generated, and enable multi-turn edits to granularly refine images step-by-step. https://t.co/k0SySQrkQu pic.twitter.com/f41KJnAtHG
