概览

What is mcp-server-unitycatalog?

A Model Context Protocol (MCP) server that exposes Unity Catalog Functions as MCP tools. It allows AI assistants to list, retrieve, create, and delete functions registered in a Unity Catalog server. This server is intended for developers using Unity Catalog who want to manage functions through natural language or AI interfaces.

How to use mcp-server-unitycatalog?

Run directly with uvx (no installation) or via Docker. Configure the server using CLI arguments or environment variables: the Unity Catalog server URL (--uc_server), catalog (--uc_catalog), schema (--uc_schema) are required; an access token (--uc_token), verbosity level, and log directory are optional. Add the server to Claude Desktop or VSCode Cline by including a JSON entry in their MCP settings files.

Key features of mcp-server-unitycatalog

Provides Unity Catalog Functions as MCP tools.
uc_list_functions: lists functions within a catalog/schema.
uc_get_function: retrieves details of a specific function.
uc_create_function: creates a new Python function (experimental).
uc_delete_function: deletes a function from Unity Catalog.
Runs via uv or Docker with no permanent install needed.

Use cases of mcp-server-unitycatalog

AI assistants querying available Unity Catalog functions.
Retrieving function signatures and metadata interactively.
Creating new Python functions in Unity Catalog through chat.
Deleting obsolete functions with natural language commands.
Integrating Unity Catalog function management into Claude Desktop or VSCode.

常见问题

What is the difference between mcp-server-unitycatalog and Unity Catalog's native API?

This server acts as an MCP bridge, making Unity Catalog Functions available directly to AI models via standard MCP tools, rather than requiring direct REST API calls.

Are there any runtime dependencies?

The server requires Python and `uv` (or Docker) to run. No additional dependencies are installed permanently when using `uvx`.

Where does function data live?

All function data resides in the remote Unity Catalog server. The MCP server is a client that queries and modifies that data.

Is the `uc_create_function` tool stable?

No, it is marked experimental and may change in future versions.

What transport and authentication are used?

The server communicates over stdio (MCP transport). Authentication is via an optional access token passed as a CLI argument or environment variable.
