An open-source MCP server, API, and CLI for records, files, permissions, and reminders. Single binary, self-hosted.
View on GitHub ↗Homepage ↗Your assistant is the interface. The Last SaaS is a server that holds your records and files, and it has no user interface of its own. Your Claude, your ChatGPT, or any agent connects to it over MCP and operates it for you.

Every SaaS is a database with a user interface on top: forms going in, dashboards coming out. That interface is work a model now does well, so this server keeps only the database side. It holds records, files, people, permissions, reminders, and history. Your assistant assembles whichever app you ask for, a gear tracker today, a client base tomorrow. When you need a new field or a different rule, you say so.
There's a hosted version, free while in beta, at thelastsaas.com. Or run it yourself; that's what the rest of this README is for.
- Records. Organizations own collections with dynamic schemas, and every record is validated against them. - Permissions. Access is controlled per member with row- and field-level filters. The bookkeeper reads every invoice and cannot open payroll. - Files. File storage attached to the records it belongs to (S3-compatible backends supported). - Reminders. Scheduled notifications, recurring or one-off, delivered by email. - History. Audit logging of every change, who made it and when, whether it was a person or an agent. - Agent access. An MCP endpoint with OAuth, plus a typed CLI that embeds an operator guide for agents.
