A recent research report by CITIC Securities highlights a significant development in the AI landscape. On March 27th, OpenAI officially announced the integration of its Agents SDK into the MCP (Model Context Protocol) service agreement. Moving forward, ChatGPT's desktop applications and Responses API will swiftly adopt this protocol as well. In the realm of AI Agents, MCP offers a marked improvement over the conventional Function Calling method for invoking external tools. By decoupling the host, server, and client, MCP significantly cuts down on the costs associated with repeated development and enhances the interoperability among diverse AI tools. Additionally, MCP is recognized as a pivotal technology for the global replication of Manus. As leading industry players expedite their support for MCP, its ecological boundaries are anticipated to broaden further, thereby accelerating the robust development of the AI industry.
