Features & Specs

  1. Standardized Interoperability

    ACP defines a common JSON-RPC based protocol between coding agents and code editors, allowing any compliant agent to work with any compliant editor without needing custom, one-off integrations for each pairing.

  2. Decoupled Development

    Editors and agents can be developed independently by different teams or organizations. Editor authors don't need to know the internals of every agent, and agent authors don't need to build UI for every editor.

  3. Reduced Duplication of Effort

    Without a shared protocol, each editor would need bespoke plugins for each agent (and vice versa), leading to an N×M integration problem. ACP reduces this to an N+M problem, saving significant engineering effort across the ecosystem.

  4. Rich, Structured Communication

    The protocol supports structured message types for things like file edits, terminal commands, permissions requests, and streaming updates, enabling more sophisticated and interactive agent-editor workflows than simple text-based interfaces.

  5. Open and Extensible

    Being an open specification (backed by Zed and other contributors) means the community can propose extensions, implementations can be built in multiple languages, and the protocol can evolve to support new agent capabilities over time.

  • Pi 1.0
    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 / 4 days ago
  • Pi.dev: You Said No MCP
    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 / 5 days ago
