mcp-server-unitycatalog: An Unity Catalog MCP server

Overview

A Model Context Protocol server for Unity Catalog. This server provides Unity Catalog Functions as MCP tools.

Tools

You can use all Unity Catalog Functions registered in Unity Catalog alongside the following predefined Unity Catalog AI tools:

1. `uc_list_functions`

2. `uc_get_function`

3. `uc_create_function`

4. `uc_delete_function`

Installation

Using uv

When using `uv` no specific installation is needed. We will use

`uvx` to directly run *mcp-server-git*.

Configuration

These values can also be set via CLI options or `.env` environment variables. Required arguments are the Unity Catalog server, catalog, and schema, while the access token and verbosity level are optional. Run `uv run mcp-server-unitycatalog --help` for more detailed configuration options.

Usage with Claude Desktop or VSCode Cline

Add this to your `claude_desktop_config.json` (or `cline_mcp_settings.json`):

Using uv

{
  "mcpServers": {
    "unitycatalog": {
      "command": "uv",
      "args": [
        "--directory",
        "//mcp-server-unitycatalog",
        "run",
        "mcp-server-unitycatalog",
        "--uc_server",
        "",
        "--uc_catalog",
        "",
        "--uc_schema",
        ""
      ]
    }
  }
}

Using docker

• Note: replace '/Users/username' with the a path that you want to be accessible by this tool

{
  "mcpServers": {
    "unitycatalog": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "mcp/unitycatalog",
        "--uc_server",
        "",
        "--uc_catalog",
        "",
        "--uc_schema",
        ""
      ]
    }
  }
}

Building

Docker:

docker build -t mcp/unitycatalog .

Future Plans

• [x] Implement support for `list_functions`.
• [x] Implement support for `get_function`.
• [x] Implement support for `create_python_function`.
• [x] Implement support for `execute_function`.
• [x] Implement support for `delete_function`.
• [ ] Implement semantic catalog explorer tools.
• [x] Add Docker image.
• [ ] Implement `use_xxx` methods. In the current implementation, `catalog` and `schema` need to be defined when starting the server. However, they will be implemented as `use_catalog` and `use_schema` functions, dynamically updating the list of available functions when the `use_xxx` is executed.
