Utilities and tools for the Stache RAG system

stache-tools

CLI and MCP server for the Stache knowledge base.

Installation

pip install stache-tools

This provides two commands:

• stache - CLI for interacting with your knowledge base
• stache-mcp - MCP server for Claude Desktop/Claude Code integration

Quick Start

1. Start Stache Server

See the Stache repository for full setup instructions, or quick start:

git clone https://github.com/stache-ai/stache-ai.git
cd stache
docker compose -f docker-compose.yml -f docker-compose.local.yml up -d

2. Configure MCP Server

Add to your Claude config file:

Claude Code (~/.claude.json or %APPDATA%\.claude\config.json on Windows):

{
  "mcpServers": {
    "stache-local": {
      "command": "stache-mcp",
      "env": {
        "STACHE_API_URL": "http://localhost:8000"
      }
    }
  }
}

Claude Desktop (~/.config/claude/claude_desktop_config.json or %APPDATA%\Claude\claude_desktop_config.json):

{
  "mcpServers": {
    "stache-local": {
      "command": "python",
      "args": ["-m", "stache_tools.mcp"],
      "env": {
        "STACHE_API_URL": "http://localhost:8000"
      }
    }
  }
}

3. Restart Claude

Restart Claude Code/Desktop to load the MCP server.

    for source in results.get("sources", []):
        print(f"{source['score']:.3f}: {source['content'][:100]}")

    # Document management
    docs = api.list_documents(namespace="examples")

    # Update document metadata
    api.update_document(
        doc_id="abc-123",
