MCP-native · public beta

Persistent filesystems for agents.

A real filesystem your agents already know how to use — over MCP.

Connect over MCP

Point any MCP-compatible agent at ctxfs and it picks up read, write, search, and edit tools out of the box. No SDK, no glue code.

A real Unix filesystem

Paths, permissions, atomic writes. Your agent doesn't need a new mental model — it already has one.

Works across machines and agents

One filesystem, many sessions. Your context stays where you left it, whether the next run is on your laptop or a CI runner.

Point your agent at ctxfs.

Add one entry to your MCP client config. The first request walks you through sign-in and consent, then the agent has a persistent home directory.
