Any ACP-compatible agent. Configure agents to run Claude Code, Codex, Grok Build, DeepSeek, Pi, or any other agent that speaks the Agent Client Protocol. Choose the runtime and model per agent across supported providers. - Source: dev.to / 1 day ago
I'd be very interested especially if ACP (https://agentclientprotocol.com/get-started/introduction) was supported over stdio so when I'm not using it directly in the terminal, I could also use it in my other ACP frontends. - Source: Hacker News / 5 days ago
Agreed. I personally don't use any MCP but I think it was a good move. I hope they'll do the same and eventually add native support for ACP (https://agentclientprotocol.com/get-started/introduction) which, on the contrary, I use quite. - Source: Hacker News / 7 days ago
