Integrations

Wherever your
agents run.

Checkpoints and rollbacks should be ambient. Fast ships integrations for the tools agents already live in.

MCP

A Model Context Protocol server exposing checkpoint, diff, and rollback tools to any MCP-capable model.

LangChain

Drop-in tools and callbacks: checkpoint before a chain runs, roll back when it goes sideways.

Cursor & coding agents

Safe experimentation for code-writing agents — capture the repo state before every run.
