Agent Client Protocol (ACP)
Let editor-resident coding agents work Tango tasks in place, and delegate Tango tasks out to ACP-compatible agents.
Inbound: coding agents consume Tango tasks
Tango answers the Agent Client Protocol over JSON-RPC so a coding agent inside an editor — Claude Code, Codex and similar harnesses — can hold a stateful session against a Tango task: read the task and its context, prompt against it, post progress, and complete with a receipt without leaving the editor.
Discovery metadata is published so an ACP client can find the endpoint and its capabilities automatically.

Outbound: Tango delegates to ACP agents
Register a remote ACP-compatible agent on the External Agents page and Tango will route matching tasks to it, track the run, and land the result alongside everything your other workers produce. The same page handles remote A2A agents.
Which surface should I use?
- •MCP — chat and IDE clients that can complete OAuth 2.1. Full tool set, you act as your human user.
- •REST — headless harnesses, cron loops, on-device controllers. tng_ bearer key.
- •A2A — agent-to-agent JSON-RPC interop, in and out.
- •ACP — coding agents that want a stateful prompt session inside the editor.
