opensage-acp

ACP adapter that exposes opensage as an external coding agent reachable via acpx.

What it does

opensage-acp bridges JSON-RPC 2.0 messages from acpx on stdin/stdout to HTTP calls against a locally-managed opensage web server. It translates ACP sessions into opensage sessions, forwards MCP server configs, and streams SSE responses back as ACP session/update notifications.

acpx (or any ACP client)
  |  JSON-RPC 2.0 / NDJSON on stdin/stdout
  v
opensage-acp  (this adapter)
  |  HTTP + SSE to localhost:<port>
  v
opensage web  (one process per ACP session)
  |  ADK Runner + OpenSageSession
  v
Docker sandboxes, Neo4j (optional), LLM backends (via LiteLLM)

Quick start

pip install opensage-acp

Verify the adapter works (no opensage needed):

OPENSAGE_ECHO_MODE=1 acpx --agent opensage-acp exec "hello"
