Remote MCP: Streamable Data Input/Output (SDIO), Server-Sent Events (SSE), Streamable HTTP
Recently, leading AI companies announced support for remote MCP, allowing an MCP client to connect to a remote MCP server via Streamable HTTP, which still supports Server-Sent Events (SSE). The Streamable Data Input/Output (SDIO) protocol remains essential for local integrations and remote services, which are accessible only through conventional APIs. In my opinion, the excitement surrounding new model releases has lost its significance. AI model developers seem to primarily focus on optimizing their models for AI benchmarks. However, the genuine innovations occur in the technologies surrounding AI models—most notably in AI agents and the supporting infrastructure in which remote MCP servers will play an important role.
