Fabric Workspace Reader MCP

MCP server for exploring Microsoft Fabric and Power BI workspaces. Available as standalone server and Desktop Extension (DXT).

Requires authentication to access Power BI workspaces (Azure CLI or Personal Access Token).

Quick Start

For Claude Desktop Users (Easiest)

Prerequisites: Python 3.8+ must be installed and in your PATH

• Mac/Linux: Usually pre-installed as python3. Use the _python3 verison.

• Windows: Download from python.org - during installation, check "Add Python to PATH". Use the _python version.

1. Download appropriate .dxt file from releases

2. Double-click to install in Claude Desktop

3. Configure authentication (see Authentication section)

For Other MCP Clients

1. Install dependencies:

pip install -r requirements.txt

2. Configure your MCP client to use this server. Example for VS Code:

{
  "mcpServers": {
    "fabric-workspace-reader": {
      "command": "python3",
      "args": ["path/to/fabric-workspace-reader-mcp.py"]
    }
  }
}

3. Authenticate using one of the supported methods:

• Personal Access Token

• Azure CLI

4. Start using the server through your MCP client.

5. For enhanced functionality, use with related MCP servers:

   • Fabric Model Reader MCP: Analyze semantic models and execute DAX queries

   • Fabric Report MCP: Manage report lifecycle and content manipulation

Authentication

The extension supports three authentication methods:

• Azure CLI: az login (recommended)

• Environment Variable: Set POWERBI_TOKEN

• System Keyring: Store token securely in system keyring

Without authentication, the extension will not be able to access any Power BI workspaces.

Workspace access denied:

• Ensure you have appropriate permissions for the workspace

• Verify the workspace exists and is accessible

• Check that you're using the correct workspace ID

Empty workspace listings:

• Confirm you have access to at least one Fabric workspace

• Verify authentication credentials are valid

• Check network connectivity to Microsoft Fabric endpoints
