Download and install Highlight from highlightai.com/download
Navigate to the plugins tab and select "Add Custom Plugin"
Configure the plugin with the settings below

Plugin Name Graph Memory RAG MCP Server

Command (node, npx, python, etc.)

Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.

Graph Memory RAG MCP Server

A Model Context Protocol (MCP) server implementation that provides graph-based memory storage capabilities. This server allows AI agents to store and retrieve information in a graph structure, making it ideal for maintaining context and relationships between different pieces of information.

Features

- In-memory graph database storage
- Entity creation and management
- Relationship creation between entities
- Query capabilities for both entities and relationships
- Delete operations with cascading relationship cleanup
- MCP-compliant interface

Installation

npm install

Dependencies

- @modelcontextprotocol/sdk: ^1.0.3
- zod: ^3.22.4

Usage

Start the server:

node app.js

API Tools

Create Entity

Creates a new entity in the graph database. - Parameters: - name: string - entityType: string - observations: string[]

Create Relationship

Creates a relationship between two existing entities. - Parameters: - fromEntityName: string - toEntityName: string - relationType: string

Query Entities

Retrieves entities by type. - Parameters: - entityType: string

Query Relationships

Retrieves relationships by type. - Parameters: - relationType: string

Delete Entity

Deletes an entity and its associated relationships. - Parameters: - name: string

Implementation Details

The server uses an in-memory graph database with two main components:
1. Entities Map: Stores entity objects with their properties
2. Relationships Map: Stores relationship objects connecting entities

Each entity contains:
- id: Unique identifier
- name: Entity name
- type: Entity type
- observations: Array of strings containing information about the entity

Each relationship contains:
- id: Unique identifier
- fromId: Source entity ID
- toId: Target entity ID
- type: Relationship type
