Common questions
Is KeepState safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.38) reached the registry today.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.
What can I use instead?

ks — the KeepState CLI
Durable agent sessions: run an AI agent in a microVM, checkpoint it, kill it, wake it — and it resumes mid-sentence, files, memory, and running processes intact.
This is the thin client. Every verb terminates at the KeepState control plane; the client is a key, the building is keepstate.ai.
Install (any one of three)
curl -fsSL https://keepstate.ai/install.sh | shbrew install keepstateai/tap/ksnpm install -g @keepstateai/cliEvery path downloads the same public-CI-built binary and verifies its SHA256 against the release's SHA256SUMS before installing. Releases carry GitHub build-provenance attestations.
Three commands to a session
ks login # browser device flowks run # a durable session on the fleet ks checkpoint --stop && ks wake # the plug-pull, survived
ks doctor checks connectivity, token, and version. ks update self-updates (checksum-verified; a mismatch is refused).
Cruise
A Cruise job is a goal, a check and a ladder of models. The fleet runs one attempt per rung from an exact save point, verifies the candidate in a verifier the agent cannot reach, and accepts only when the check passes. A failed rung escalates to the next one; after the last rung the job waits in your review queue. Nothing is accepted on a model's word.
ks cruise init --goal "make the inventory tests pass" # drafts .keepstate/cruise.jsonks cruise approve # locks it: .keepstate/cruise.lock ks cruise run # uploads the workspace, starts the job ks cruise status # rung, attempts, save points, spend, verdict ks cruise artifact # the accepted tarball, sha256-verified
init reads the repository: the check is the test command it finds (pytest, npm test, go test) or the one you name with --tests. A goal with no check is not a job; init stops and says so. It makes no request and never calls a model. approve records the manifest's digest; run refuses a draft that is not approved, a test or workspace changed since approve, and a workspace over 50 MiB (.git and .keepstate excluded). Defaults: 1800 s per attempt and a $2 spend ceiling (--spend); the ladder comes from the model table (ks cruise models, --ladder family:model,...). ks cruise logs, cancel and resume complete the set. Every --help makes no request.
Uninstall (one line)
