Show HN: Built an MCP server using Cloudflare's Code Mode pattern Read this article by Cloudflare this morning https://ift.tt/YPz7Q6F the main argument being that LLMs are much better at writing typescript code than tool calls because they've seen typescript code many more times. HN Discussion: https://ift.tt/EZqDnsC https://ift.tt/kjTlrYd Deno provides a great sandbox environment for Typescript code execution because of its permissions system which made it easy to spin up code that only has access to fetch and network calls. Stick an MCP proxy on top of that and you've got "CodeMode" (code intermixed with MCP tool calls) for more advanced workflow orchestration. https://ift.tt/Vs84Cuj There's a lot of things that can be improved here. Like a virtual file system for the agent to actually build up its solution instead of being forced to one shot the solution but the bones are there. https://ift.tt/Vs84Cuj September 28, 2025 at 11:23PM
