Problem

LLM chats lose memory between sessions, forcing developers to repeat preferences, architectural rules, and project context.

Solution

A local knowledge-graph MCP server that automatically stores entities, relations, and observations across conversations.

Challenge

Dynamically querying and updating graph relations without polluting the LLM prompt context.

Key Features

  • Entity & Relation graph storage
  • Continuous cross-session memory
  • Search and retrieve facts
  • Local JSON persistence

Target User

Anyone using AI assistants across recurring, long-term engineering projects.

Impact

"Gave AI assistants true continuity and long-term memory across disjoint chat sessions."

How to Use

1

Install Memory Server

Add '@modelcontextprotocol/server-memory' to your MCP configuration.

2

Tell AI Facts

Say: 'Remember that our project uses Tailwind CSS v4 and PostgreSQL with Drizzle ORM'.

3

Recall in New Chats

In a new session, ask: 'What stack do we use for the database?' and the agent will retrieve it from memory.
