MCP Server for Context-Aware Knowledge Management

An MCP (Model Context Protocol) server that integrates multiple data sources—Google Drive, RAG (Retrieval-Augmented Generation), and MCP Memory Server—to provide context-aware knowledge management for AI assistants.

Note: 日本語版は README.ja.md を参照してください。

Features

• Session Management: Save and restore work states, automatically suggest relevant documents
• Project Management: Switch between multiple projects, search for similar projects
• Document Operations: Google Docs integration with automatic catalog registration
• Catalog Management: Semantic search with Google Sheets synchronization
• Knowledge Management: RAG-based knowledge storage and retrieval

Requirements

• Python 3.11 or higher
• Google Cloud project with OAuth 2.0 credentials
• RAG server (ChromaDB compatible)
• MCP Memory Server (optional)

Installation

# Clone the repository
git clone https://github.com/SpirrowGames/spirrow-prismind.git
cd spirrow-prismind

# Install the package
pip install -e .

Configuration

1. Copy the example config:

   cp config.toml.example config.toml
   

2. Set up Google OAuth credentials:

   • Create a project in Google Cloud Console
   • Enable Google Docs, Drive, and Sheets APIs
   • Create OAuth 2.0 credentials (Desktop application)
   • Download credentials.json and place it in the config directory

3. Configure external services in config.toml:

   • RAG Server endpoint (ChromaDB compatible)
   • MCP Memory Server connection (optional)

Usage

With Claude Desktop

Add to your Claude Desktop configuration (claude_desktop_config.json):

{
  "mcpServers": {
    "prismind": {
      "command": "spirrow-prismind",
      "env": {
        "PRISMIND_CONFIG": "/path/to/config.toml"
      }
    }
  }
}

With Claude Code

Add to your Claude Code settings:

{
  "mcpServers": {
    "prismind": {
      "command": "spirrow-prismind",
      "env": {
        "PRISMIND_CONFIG": "/path/to/config.toml"
      }
    }
  }
}

Available Tools

Session Management

Tool	Description
start_session	Start a session and restore previous state
end_session	End session and save state for handoff
save_session	Save intermediate session state
list_sessions	List all sessions for a project
delete_session	Delete a specific session
list_context_authors	List the distinct context authors/roles saved for a project

start_session / end_session / save_session / delete_session accept an optional author argument. It adds a partition segment to the session key (prismind:session:{project}:{user}:{author}), so one project+user can hold multiple independent contexts — one per author/role. An empty author keeps the legacy key for backward compatibility.
