SummaryAnthropic Engineering explains how agents can use code execution with the Model Context Protocol to handle more tools while using fewer tokens, reducing context overhead by up to 98.7%, by writing code to call tools rather than making direct tool calls.
Why it mattersA primary-source architectural pattern from the MCP authors, with a concrete 98.7% context-reduction figure useful to anyone scaling agents across many tools.
