Choose UnlimitedEvery plan includes search, a data viewer and the same five operations: put, get, list, search, delete. No per-agent fees. Paid plans renew monthly; final taxes and currency are shown at checkout.
The open-source core is free to self-host. Bring your own server and keep your data yours. Hosted plan limits do not apply to self-hosting.

No object-count cap. It is not unlimited traffic: 64 KB per object, 600 requests and 300 writes per minute still apply. AgentStore is for structured objects—not bulk files, spam, or abusive workloads.
New saves pause. You can still read, edit and delete existing objects within the rate limits. Upgrade or delete an object to make room. Expired objects count until deleted.
Fixed one-minute windows, shared across your account and API keys. Writes include creates, updates and deletes. Batch MCP requests also count each tool call. Rate-limited HTTP requests include a retry time.
Open Billing in your workspace to upgrade after reviewing the prorated charge. Paddle's portal handles invoices, payment methods and cancellation. Scheduled cancellation keeps your plan until the paid period ends; your objects are not deleted.
