apra-fleet

Overview

Apra Fleet is a comprehensive MCP server that pairs AI coding agents into doer-reviewer loops for higher quality code and coordinates them across machines via SSH. It enables distributed computing with AI agents, allowing developers to run test suites on Linux while developing on macOS, or have multiple agents work on different parts of a project in parallel. The system includes optional Project Manager skills for structured multi-step workflows, with task state persistence across sessions.

FAQ

What is a 'doer-reviewer loop'?

It's a workflow where two AI agents are paired - one writes code while the other reviews it. The Project Manager orchestrates the handoff with structured checkpoints, ensuring every change gets reviewed before you even look at it.

Can I mix different LLM providers with Apra Fleet?

Yes, Fleet members can run different LLM backends. The recommended setup uses Claude for the Project Manager role (orchestrator), any provider for the Doer role, and premium tier models for the Reviewer role to catch subtle issues.

Does Apra Fleet require any background services or daemons?

No, there are no background services or daemons. The fleet server starts on-demand when Claude Code connects and stops when the connection closes.
