pumaDB

pumaDB is a small hosted memory layer that gives AI agents a persistent place to store user preferences, project conventions, research notes, and task state — without forcing the developer to run a database. It exposes both an MCP server and a REST API, so agents reach the same store regardless of how they're orchestrated.

Each row is a JSON blob with a key, automatic version history, and safety hooks for soft-delete and rollback. The free tier covers 20 tables and 1,000 rows per table, which is enough to ship a working agent and decide later if scale warrants migration.

The product targets teams who keep redesigning a memory tier on every agent project. By pinning durability, schema flexibility, and history to one hosted endpoint, pumaDB lets the agent focus on reasoning instead of state management.
