The coding agent Pi, initially a vocal critic of the Model Context Protocol (MCP), has integrated MCP as a core feature. Creator Mario Zechner had previously argued that MCP's standard implementation was inefficient, consuming a significant portion of an agent's context window with tool definitions. However, changes in the MCP protocol itself, its widespread adoption, and Pi's development of a new integration method called Codemode, which uses JavaScript within a sandbox to access tools, led to the shift.
