# MCX (Modular Code Execution)

> Use this tool when you need to execute sandboxed JavaScript and TypeScript code to filter, aggregate, and transform data locally, reducing token usage and improving efficiency. It solves problems related to data processing and token optimization by allowing AI agents to run modular code instead of calling individual tools directly. The MCX tool takes in JavaScript and TypeScript code as input and returns processed data as output, making it ideal for use cases that require local data manipulation and transformation.
