What is pumaDB?
pumaDB provides a specialized API for AI agents to store and retrieve structured memory, eliminating the need for developers to set up and manage traditional databases. It allows agents to remember facts, settings, task states, and other JSON records across sessions, making their interactions smarter and more consistent. The service offers both a hosted Managed Connector Protocol (MCP) for direct agent integration and a REST API for server-side applications.
Designed for simplicity and agent-specific use cases, pumaDB supports various memory types like user preferences, project conventions, and research clippings. It includes built-in safety features such as scoped table limits, rate limits, and automatic version history, ensuring memory is manageable and reviewable. This tool is ideal for developers building AI agents or applications that require lightweight, durable, and easily accessible memory without the overhead of database administration.
