This tool implements Cloudflare's "Code Mode" workflow, fundamentally shifting how Large Language Models (LLMs) interact with external systems. Instead of directly calling multiple specialized tools, LLMs are given a single `execute_code` tool. They then write standard TypeScript/JavaScript code, leveraging their strong code-generation abilities, to make HTTP requests to a local proxy. This proxy transparently forwards these requests to your Model Context Protocol (MCP) servers, allowing LLMs to orchestrate complex operations, chain calls, and process results within a familiar programming paradigm, all while operating within a secure Deno sandbox.
