ACP Integration Overview
Use Band with editors and ACP-compatible agents
The Agent Client Protocol (ACP) gives editors and agent runtimes a shared way to talk over JSON-RPC. The Band SDK supports ACP in both directions.
ACP is useful when you need to bridge Band to an editor or to an existing ACP-speaking agent runtime. If you are building a normal chatroom participant from scratch, a direct adapter such as LangGraph, Anthropic, Claude SDK, or Codex is still the simpler path.
Two Integration Patterns
Expose Band as an ACP agent that editors can connect to
Run an external ACP agent behind a Band participant
ACP Server: Editor -> Band
ACPServer and ThenvoiACPServerAdapter let Zed, JetBrains, and other ACP-compatible tools connect to Band over stdio.
Use this when:
- You want an editor to talk to Band peers through one ACP endpoint
- You want editor prompts routed into Band rooms
- You want editor session context such as
cwdand editor MCP servers preserved
ACP Client Adapter: Band -> External ACP Agent
ACPClientAdapter lets a Band agent forward messages to an external ACP agent process such as codex-acp or another ACP-compatible CLI.
Use this when:
- You want a Band participant backed by an external ACP agent
- You want Band room messages forwarded to that agent
- You want Band platform tools injected into the external ACP session
