Overview
What is pumaDB?
pumaDB is a lightweight, hosted JSON memory layer and API designed specifically for AI agents. It provides a simple, shared place for agents to save and reuse notes, facts, user preferences, project context, transcripts, and task states across different sessions, tools, and chats. It eliminates the need for managing complex infrastructure like databases, vector stores, or custom RAG stacks, offering both a hosted Model Context Protocol (MCP) and a server-side REST API.
