The Agent Loop is the New OS
Blog post from Harness
The Harness MCP (Model Context Protocol) server is designed to enhance agent infrastructure by minimizing context overhead and focusing on a small set of composable, self-describing abstractions. Inspired by systems like Unix, Git, and SQL, it emphasizes small, stable interfaces, uniform contracts, and runtime introspection. The server acts as a kernel, mediating access to underlying systems and enabling agents to operate efficiently by focusing on reasoning rather than parsing numerous endpoints. With a design that includes generic tools and a dispatch mechanism, the MCP server supports scalable capability growth while keeping the agent's context focused on essential reasoning tasks. By applying principles such as demand-paged schema discovery and centralized dispatch, the server optimizes for runtime selection and composition, which is crucial for the next generation of agent-native systems.
