Fabric Report MCP

MCP server for managing Microsoft Fabric Reports with lifecycle management, filtering, and content manipulation.

Important:

• Requires Azure AD authentication to access Microsoft Fabric workspaces.

• Requires PBIR format reports for most tools.

Quick Start

For Claude Desktop Users (Easiest)

Prerequisites:

1. Python 3.8+ must be installed and in your PATH

   • Mac/Linux: Usually pre-installed as python3

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

2. Install required Python packages:

   # For Mac/Linux:
   pip3 install fastmcp msal httpx pydantic python-dotenv
   
   # For Windows:
   pip install fastmcp msal httpx pydantic python-dotenv

Installation:

1. Download fabric-report-mcp.dxt from releases

2. Double-click to install in Claude Desktop

3. Configure Azure AD authentication (see Authentication section)

For Other MCP Clients

1. Clone repository

2. Install dependencies:

pip install -r requirements.txt

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

{
  "mcpServers": {
    "fabric-report-mcp": {
      "command": "python3",
      "args": ["path/to/fabric-report-mcp/src/server.py"]
    }
  }
}

4. Set up authentication using environment variables

5. Start using the server through your MCP client

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

   • Fabric Workspace Reader MCP: Explore workspaces and discover resources

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

Authentication

There are three options for authentication:

1. Azure CLI, which you can install and then login by using az login

2. Azure SDK

3. Configuration of a personal access token or Azure AD app registration

Troubleshooting

Common Issues

Authentication failures:

• Verify Azure AD credentials are correctly configured

• Ensure the service principal has necessary Fabric permissions

• Check that the tenant ID, client ID, and client secret are valid

Connection timeouts:

• Verify network connectivity to Microsoft Fabric endpoints

• Check firewall settings if running behind corporate proxy

• Consider increasing timeout values for large reports

Report definition errors:

• Ensure PBIR format compatibility when using report definitions

• Validate JSON structure before sending updates

• Check that all required fields are present in report objects
