A2CR

A2CR solves the AI handoff problem: when your context window fills up or you switch between Codex, Claude Code, or Roo Code, you lose the thread. This server gives you save_context and resume_context tools that store compact WorkBaton checkpoints (goal, current state, next action, decisions, blockers) and optional WorkStash notes. Everything is client-encrypted before hitting the hosted A2CR service at a2cr.app, so you need an API key. The Python wrapper ships via PyPI as a2cr-mcp, and there's an MCPB package for Claude Desktop. Use it when a coding task spans multiple sessions and you want structured resume state instead of pasting transcript snippets into the next window.
