Features and specs

What each product offers, as listed by its team.

ACP
Agent Client Protocol 5 features
Glean 0 features
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

Possible disadvantages

  • Early-Stage Adoption
    As a relatively new protocol, only a limited number of editors and agents currently support ACP, which reduces its practical usefulness until more of the ecosystem adopts it.
  • Implementation Overhead
    Both editor and agent developers must invest time to implement the protocol correctly, including handling JSON-RPC messaging, permission flows, and streaming updates, which adds complexity compared to simpler, ad-hoc integrations.
  • Feature Lag Behind Native Integrations
    Because ACP is a generalized protocol, it may not immediately expose every specialized feature of a specific agent or editor that a deep, custom-built native integration could provide.
  • Governance and Evolution Risk
    As with any open protocol still maturing, there's uncertainty around governance, versioning stability, and how backward compatibility will be handled as the spec evolves, which could create friction for early adopters.
  • Limited Ecosystem Tooling
    Debugging tools, comprehensive documentation, and community resources for troubleshooting ACP-based integrations are still developing, making it harder to diagnose issues compared to more established protocols.

  • AgentConnect vs. Claude Tag: comparing the two ways to bring agents into team chat
    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 / about 8 hours ago
  • 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 / 5 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 / 6 days ago
