ACP adapter for the Claude Agent SDK

npm

Use Claude Agent SDK from ACP-compatible clients!

This tool implements an ACP agent by using the official Claude Agent SDK, supporting:

  • Context @-mentions
  • Images
  • Tool calls (with permission requests)
  • Following
  • Edit review
  • TODO lists
  • Nested subagent transcripts
  • Interactive (and background) terminals
  • Custom Slash commands
  • Client MCP servers
  • Session-scoped long-running goals through the provider-neutral goal extension
  • Structured errors, recovery, and warnings through the opt-in session failure extension
  • Tool permission presentation, editable choices, and durable effects through the permission extension

Learn more about the Agent Client Protocol.

Subagent sessions

Subagents are exposed only after bilateral capability negotiation. Until the released ACP SDKs preserve the draft clientCapabilities.subagents field, a supporting client may advertise nativeSubagentSessions in _meta.jetbrains.air.capabilities; the adapter mirrors the capability in its initialize response. The canonical field remains supported and takes precedence once it is available. Without either client signal, Agent/Task lifecycle keeps its legacy ordinary ACP tool-call representation and child interactions stay on the root session. Clients that use the historical _meta["subagent-transcript"] capability or forwardSubagentText session option retain the flattened child transcript behavior.
