Anthropic MCP Google Drive Client

This client uses the Anthropic Model Context Protocol (MCP) to generate a memory knowledge graph from Google Drive data. It processes files, emails, and calendar events to create a connected graph of information.

Features

• Connects to Google Drive, Gmail, and Google Calendar
• Processes documents, spreadsheets, and other file types
• Analyzes content using MCP to extract entities and relationships
• Stores the knowledge graph in Neo4j
• Handles folders recursively
• Maintains relationships between related items

Prerequisites

1. Node.js 18 or higher
2. Neo4j database instance
3. Google Cloud project with Drive, Gmail, and Calendar APIs enabled
4. MCP server running locally or remotely

Setup

1. Clone the repository:

npm run build

Usage

Run the client:

npm start

The client will:

1. Connect to the MCP server
2. Authenticate with Google services
3. Process your Google Drive folder
4. Create a knowledge graph in Neo4j

Knowledge Graph Structure

The graph consists of these main node types:

• File: Documents, spreadsheets, etc.
• Email: Gmail messages
• Event: Calendar events

Relationships between nodes are created based on:

• Content analysis
• Temporal relationships
• References between items
• Shared metadata
