MemoryMesh
MemoryMesh is a knowledge graph server that enables AI models to maintain consistent, structured memory across conversations through schema-based tools and dynamic node management. It provides capabilities for defining custom data structures via schemas that automatically generate tools for adding, updating, and deleting knowledge graph nodes, with support for relationships and metadata to guide AI interactions. The server addresses the problem of maintaining coherent, persistent context in text-based RPGs and interactive storytelling applications where AI agents need to track complex, interconnected information about characters, settings, and narrative state.

MemoryMesh
MemoryMesh is an MCP server that gives AI models a structured, long-term memory in the form of a knowledge graph. You describe the kinds of things you want to remember in small schema files (people, projects, characters, locations, books...), and MemoryMesh turns each one into tools the AI uses to add, update and delete that information, linking related items as it goes.
It works for anything you can describe as things and the connections between them: a text-based RPG world, the people and teams at your company, a personal CRM, or your reading notes.
Based on the Knowledge Graph Memory Server from the MCP servers repository.
