Code Mode: Using MCP with Generated TypeScript APIs

🧩 Cloudflare introduces Code Mode, a new approach that converts Model Context Protocol (MCP) tool schemas into a generated TypeScript API so LLMs write code instead of emitting synthetic tool-call tokens. This lets models leverage broad exposure to real-world TypeScript, improving correctness when selecting and composing many or complex tools. Code Mode executes the generated code inside fast, sandboxed Cloudflare Workers isolates that expose only typed bindings to authorized MCP servers, preserving MCP's uniform authorization and discovery while reducing token overhead and orchestration latency.
