Announcing DAC 1.0 — One Manager, a Fleet of Agents

September 25, 2026 • 304 words • 2 min read

Running one coding agent is straightforward. Running a fleet — across servers, with cost accounting, backups and an audit trail — is what DAC is for.

What DAC is

DAC (Dispatched Agent Connector) is an MIT open-source control plane on top of DeepSeek Harness. DeepSeek Harness provides the agent runtime (sessions, tools, sandbox, filesystem); DAC adds authentication, chat relay, brain dispatch, node and machine management, skill inventory, cost accounting, and backup & restore.

One command installs the default trio: a manager (the control plane), a brain (cross-domain planning, read-only on workspaces), and your personal workspace agent (reads files, writes files, leaves a git trail).

What ships in 1.0.0

  • Fleet management — machines joined by a node agent with zero inbound ports, nodes as container workers or host processes, a live topology view with heartbeat edges, per-node DSH version pinning.
  • Unified conversation — streaming chat against any node, tool cards, inline question and approval handling, per-session model selection and access-mode switching.
  • API access — every node reachable through one authenticated gateway prefix, so third-party clients get the same agents the UI has.
  • A brain that dispatches — cross-domain planning with delegation frames; read-only on workspaces, execution is always delegated.
  • Operations built in — audit log, peak/off-peak costing with budget breakers, encrypted backups with a restore drill, self-update with automatic rollback.
  • Bilingual UI — English by default, Chinese one click away.
  • Safe by default — loopback-only node ports, approval cards for dangerous operations, agent tokens that rotate with a grace window, first login forces a password change.
