Databricks Permissions Server

A Model Completion Protocol (MCP) server that provides access to Databricks permissions, credentials, and Git credentials via the MCP protocol. This allows LLM-powered tools like Claude to interact with Databricks permissions management systems.

Features

• MCP Protocol Support: Implements the MCP protocol to allow LLMs to manage Databricks permissions
• Databricks API Integration: Provides secure access to Databricks permissions REST APIs
• Permission Management: Comprehensive tools for managing permissions on various Databricks resources
• Git Credentials Management: Tools for creating, listing, updating, and deleting Git credentials
• Async Support: Built with asyncio for efficient operation

Installation

Prerequisites

• Python 3.10 or higher
• MCP-compatible client (e.g., Claude Desktop)

Setup

1. Clone the repository:

   git clone https://github.com/yourusername/databricks-permissions-mcp-server.git
   cd databricks-permissions-mcp-server
   

2. Set up the project:

   # Create and activate virtual environment
   python -m venv .venv
   
   # On Windows
   .\.venv\Scripts\activate
   
   # On Linux/Mac
   source .venv/bin/activate
   
   # Install dependencies in development mode
   pip install -e .
   

3. Set up environment variables:

   # Windows
   set DATABRICKS_HOST=https://your-databricks-instance.azuredatabricks.net
   set DATABRICKS_TOKEN=your-personal-access-token
   
   # Linux/Mac
   export DATABRICKS_HOST=https://your-databricks-instance.azuredatabricks.net
   export DATABRICKS_TOKEN=your-personal-access-token
   

   You can also create an .env file based on the .env.example template.

Running the MCP Server

To start the MCP server, run:

# Windows
.\start_mcp_server.ps1

# Linux/Mac
./start_mcp_server.sh

Using with Claude Desktop

1. In Claude Desktop, click the "+" button to add a new tool
2. Select "Custom command"
3. Enter a name like "Databricks Permissions"
4. For the command, enter: python -m src.server.databricks_permissions_mcp_server
5. Click "Save"
6. You can now ask Claude to perform tasks like:
   • "List all Git credentials in Databricks"
   • "Show permissions for cluster X"
   • "Update permissions for job Y to give user Z 'CAN_MANAGE' access"
