This protocol is implemented by zed industries (https://agentclientprotocol.com), for communication between editors and genai agents.
It’s implemented in zed obviously (https://zed.dev/blog/bring-your-own-agent-to-zed) and in neovim, so I wanted to suggest it as an idea for sublime text also, in a manner as LSP-copilot chat, for example.
It looks like there is significant overlap with the Model Context Protocol (MCP) which is used by VS Code (I might be wrong because I didn’t take a very close look yet).
I think the biggest obstacle for a Sublime plugin is that the UI is restricted by what is available in the ST API (input handlers, output panels, HTML sheets, …) and therefore they have to fiddle with all kinds of workarounds to utilize these generic components for the UI. On the other hand VS Code and Zed seem to intend to make the AI stuff directly a part of the editor, so they can put a lot of effort in implementing UI components that are specifically designed for the communication with AI agents / LLM.
I don’t know about ACP but MCP is a security nightmare. Nobody should be using that on their computer in its current state. It’s horrifying that anyone does. I’ll assume after a brief search that ACP creates similar vulnerabilities.
It’s not my business if someone wants to punch a Boeing-sized security hole in their Sublime Text editor by installing a dangerous plugin, but I certainly hope Sublime HQ does not spend any developer cycles supporting such endeavors in the core editor, including making such plugins easier to create. There are way too many other more productive things they could be doing.
Yes, it is similar to Anthropic’s MCP, it’s the same idea with little overhead to make it work.
Besides Gemini CLI and Claude code, Qwen code and opencode are already in implementation phase
