Kakao has moved to expand an "everyday AI" ecosystem that links with external AI services by advancing its open-platform features.
Kakao said on the 24th that it added a "toolbox" feature, which lets users manage and call multiple tools in one place, to "Play MCP," an MCP-based open platform unveiled in July.
MCP (Model Context Protocol) is a communication protocol that standardizes how AI models interact with external data and tools, making data exchange between different services easy. With this update, users can choose multiple MCP tools registered on Play MCP, store them in the toolbox, and use them immediately on external AIs such as ChatGPT or Claude with only Kakao account authentication. Using the toolbox streamlines the integration steps that previously had to be done for each AI service, unifying the flow so that, after account authentication, users request the needed tools from the AI.
Users can execute requests such as "Send what you just told me to my KakaoTalk chat with me," "Tell me my schedule for today," "Show me the list of gifts I received," and "Play the Melon song I listened to on this day last year again" on external AIs. After logging in to the Play MCP site and adding tools, integration is completed by registering a customized MCP server URL in ChatGPT's developer mode and authenticating the toolbox.
Yu Yong-ha, performance leader of Kakao AI Agent Platform, said it "means AI is evolving from a simple conversation partner into an 'everyday AI' that understands and acts on users' real daily lives."
