This seems exactly right. Its pretty common to watch your agent making the same mcp tool call again and again as it works through a list. These kinds of cases are solved by letting the agent just call any of its mcp tools in a script.
This is interesting, but it seems like it's only exposed as a Cloudflare service now, rather than as a tool I can use locally (unless I missed something)?
It doesn't seem to me that isolates are sufficiently unique technology to warrant this only running on a server. Surely we can spin up a V8 locally or something and achieve the same thing?
Hopefully the popular MCP clients will start implementing this approach, if it works as well as claimed.

Though AFAIK Wrangler is really only intended for development and not local deployment.
Hmm but that's just a development environment for the remote server, no? It's not a tool meant for mass use.
Nice! Seems very similar to the concept explored by Google (CaMeL) https://arxiv.org/abs/2503.18813
