OpenMetadata MCP server

The MCP server for OpenMetadata enables interaction with OpenMetadata through a standardized Model Context Protocol interface. It wraps the OpenMetadata REST API, allowing MCP clients to access and manage metadata in a consistent way.

Installation and Setup

Environment Variables Configuration

To use the MCP server, you need to set up environment variables for authentication with your OpenMetadata instance. You have two authentication options:

Token Authentication (Recommended)

OPENMETADATA_HOST=<your-openmetadata-host>
OPENMETADATA_JWT_TOKEN=<your-jwt-token>

Basic Authentication

OPENMETADATA_HOST=<your-openmetadata-host>
OPENMETADATA_USERNAME=<your-username>
OPENMETADATA_PASSWORD=<your-password>

Usage

Integration with Claude Desktop

You can add the MCP server to your Claude Desktop configuration by modifying the claude_desktop_config.json file.

Using Token Authentication (Recommended)

{
  "mcpServers": {
    "mcp-server-openmetadata": {
      "command": "uvx",
      "args": ["mcp-server-openmetadata"],
      "env": {
        "OPENMETADATA_HOST": "https://your-openmetadata-host",
        "OPENMETADATA_JWT_TOKEN": "your-jwt-token"
      }
    }
  }
}

Using Basic Authentication

{
  "mcpServers": {
    "mcp-server-openmetadata": {
      "command": "uvx",
      "args": ["mcp-server-openmetadata"],
      "env": {
        "OPENMETADATA_HOST": "https://your-openmetadata-host",
        "OPENMETADATA_USERNAME": "your-username",
        "OPENMETADATA_PASSWORD": "your-password"
      }
    }
  }
}

Alternative Configuration with UV

If you prefer using uv instead of uvx, you can use this configuration:

Token Authentication

{
  "mcpServers": {
    "mcp-server-openmetadata": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/mcp-server-openmetadata",
        "run",
        "mcp-server-openmetadata"
      ],
      "env": {
        "OPENMETADATA_HOST": "https://your-openmetadata-host",
        "OPENMETADATA_JWT_TOKEN": "your-jwt-token"
      }
    }
  }
}

Basic Authentication

{
  "mcpServers": {
    "mcp-server-openmetadata": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/mcp-server-openmetadata",
        "run",
        "mcp-server-openmetadata"
      ],
      "env": {
        "OPENMETADATA_HOST": "https://your-openmetadata-host",
        "OPENMETADATA_USERNAME": "your-username",
        "OPENMETADATA_PASSWORD": "your-password"
      }
    }
  }
}

Make sure to replace /path/to/mcp-server-openmetadata with the actual path to your repository.

Running the Server Manually

You can also run the server directly from the command line:

python src/server.py

Available Command Line Options

• --port: Port to listen on for SSE (default: 8000)
• --transport: Transport type (stdio/sse, default: stdio)

Supported Features

Currently, the MCP server implements the following OpenMetadata features:

• Tables
  • List Tables
  • Get Table (by ID)
  • Get Table by Name
  • Create Table
  • Update Table
  • Delete Table

Other OpenMetadata features are planned for future implementation.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
