pumaDB

pumaDB is a specialized API that acts as a memory layer for AI agents. It lets these agents store small, durable JSON records—like user preferences, project notes, or task state—and retrieve them later across different sessions and platforms. Instead of building and maintaining your own database, you connect to pumaDB's API and start writing data immediately. It's designed specifically for the kind of small, structured information that agents need to remember to work more effectively over time.

The tool works through two main interfaces: a hosted MCP (Model Context Protocol) server for AI clients like ChatGPT and Claude, and a standard REST API for server-side applications. You can store various types of information, from user communication preferences to research notes, all organized in simple tables with JSON rows. What makes it stand out are the built-in safety features: automatic version history, rate limits per key, natural language editing capabilities for agents, and recoverable archives for all changes.

This is most valuable for developers building AI agent applications that need persistent memory across conversations. Use cases include maintaining user preferences between chat sessions, storing project-specific conventions that agents should reference, keeping research findings from one investigation to the next, and preserving task state for long-running workflows. It's particularly useful when you want agents to remember context without the overhead of database management.
