Frequently asked questions

What does the A2CR MCP server do?

Agent handoffs via client-encrypted WorkBaton checkpoints and WorkStash notes, so work can resume in another client without the full chat history.

Is the A2CR MCP server free?

The server is free, but you will likely need an account. The server itself is free, but it connects to a service that needs an account or API key, which may have paid tiers. Check the provider for current pricing.

Does A2CR run locally or remotely?

Local. Runs on your machine (stdio). You install it with npx, uvx, Docker or from source.

How do I add A2CR to Claude Code?

Run: claude mcp add a2cr -- uvx a2cr-mcp
