EVENT DOSSIER
In September 2026, with the deepening of the artificial intelligence application ecosystem, the three core protocols related to data interaction and model scheduling – Model Context Protocol (MCP), Application Context Protocol (ACP), and Large Scale Protocol (LSP) – officially emerged as competing entities. These protocols focus on context management, application layer integration, and large-scale collaborative scheduling, collectively forming the infrastructure standard system of the current AI era.
The LSP, MCP, and ACP protocols are building the next-generation software-based communication network. Among them, LSP is responsible for code completion, while ACP supports agent collaboration. Together, they form the communication architecture of the new generation of software ecosystems.
