Use cases

• Save and retrieve conversation context or session state in MCP-compatible AI assistants
• Persist outputs from tool calls for later analysis or reuse
• Enable agents to share JSON-based data across multiple tool invocations

Pros

• Lightweight JavaScript implementation with minimal dependencies
• Simple JSON document storage, easy to inspect and debug
• Works within the MCP ecosystem, allowing direct integration with supported LLM tools

Cons

• Limited to JSON document storage, not a general-purpose SQL or NoSQL database
• Low community adoption (32 stars) may mean fewer examples or slower evolution
• No built-in authentication or access control—designed for local or trusted environments
