PBIXRay MCP Server

Info!

Those interested in this project might also be interested in this follow-up project, tabular-mcp, which allows running DAX queries against a local PowerBI model. Support is highly appreciated!

A (MCP) server for PBIXRay.

This MCP server exposes the capabilities of PBIXRay as tools and resources for LLM clients to interact with Power BI (.pbix) files.

Features

Loading and analyzing PBIX files
Data model exploration
- Listing tables in the model
- Retrieving model metadata
- Checking model size
- Getting model statistics
- Getting comprehensive model summary
Query language access
- Viewing Power Query (M) code
- Accessing M Parameters
- Exploring DAX calculated tables
- Viewing DAX measures
- Examining DAX calculated columns
Data structure analysis
- Retrieving schema information
- Analyzing table relationships
- Accessing table contents with pagination

The list of tools is configurable, so you can choose which tools you want to make available to the MCP client.

Requirements

Python 3.13 (recommended) or Python 3.10+
uv package manager
Windows PowerShell

Check Your Python Version

python --version # Should show Python 3.13.x (recommended) or 3.10+ minimum

Installation and Setup

First Time Setup - Create Virtual Environment

# Navigate to your project directory cd "d:\AI\Guyen\pbixray-mcp-server-main" # Check Python version (must be 3.10+) python --version # Create virtual environment with Python 3.13 uv venv --python 3.13 # Activate the virtual environment .venv\Scripts\Activate.ps1 # Install dependencies uv pip install mcp pbixray numpy # Test that everything works python src/pbixray_server.py --help

Verification

Once everything is set up, you can test the server:

# Navigate to your project directory cd "d:\AI\Guyen\pbixray-mcp-server-main" # Activate the virtual environment .venv\Scripts\Activate.ps1 # Test the server python src/pbixray_server.py --help

You should see output similar to:

usage: pbixray_server.py [-h] [--disallow DISALLOW [DISALLOW ...]] [--max-rows MAX_ROWS] [--page-size PAGE_SIZE] [--load-file LOAD_FILE] PBIXRay MCP Server options: -h, --help show this help message and exit --disallow DISALLOW [DISALLOW ...] Specify tools to disable --max-rows MAX_ROWS Maximum rows to return for table data (default: 10) --page-size PAGE_SIZE Default page size for paginated results (default: 10) --load-file LOAD_FILE Automatically load a PBIX file at startup

Claude Desktop Configuration

My Real Claude_Desktop_config.json

Path: C:\Users\guyen\AppData\Roaming\Claude

Content:

{ "mcpServers": { "test-server": { "command": "D:\\AI\\Guyen\\Claude-mcp-agentic-system\\.venv\\Scripts\\python.exe", "args": ["D:\\AI\\Guyen\\Claude-mcp-agentic-system\\servers\\basic_server_clean.py"], "env": {} }, "pbixray": { "command": "D:\\AI\\Guyen\\pbixray-mcp-server-main\\.venv\\Scripts\\python.exe", "args": ["D:\\AI\\Guyen\\pbixray-mcp-server-main\\src\\pbixray_server.py"], "env": {} }, "powerbi": { "command": "D:\\Projects\\powerbi-mcp-master\\.venv\\Scripts\\python.exe", "args": [ "D:\\Projects\\powerbi-mcp-master\\src\\server.py" ], "env": { "PYTHONPATH": "D:\\Projects\\powerbi-mcp-master", "OPENAI_API_KEY": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" } } } }

Alternative Configuration with PowerShell

If you prefer using PowerShell commands:

{ "mcpServers": { "pbixray": { "command": "powershell.exe", "args": [ "-Command", "cd 'd:\\AI\\Guyen\\pbixray-mcp-server-main'; .venv\\Scripts\\Activate.ps1; python src/pbixray_server.py" ] } } }

Alternative Configuration with uv run

If you prefer using uv run (which handles the virtual environment automatically):

{ "mcpServers": { "pbixray": { "command": "powershell.exe", "args": [ "-Command", "cd 'd:\\AI\\Guyen\\pbixray-mcp-server-main'; uv run python src/pbixray_server.py" ] } } }

Usage

Windows Path Usage

When using the PBIXRay MCP Server on Windows, you can use standard Windows paths directly:

# Load a PBIX file using Windows path load_pbix_file("C:\\Users\\YourName\\Documents\\file.pbix") # Or using forward slashes (also works) load_pbix_file("C:/Users/YourName/Documents/file.pbix")

Command Line Options

The server supports several command line options:

--disallow [tool_names]: Disable specific tools for security reasons
--max-rows N: Set maximum number of rows returned (default: 100)
--page-size N: Set default page size for paginated results (default: 20)

Query Options

Tools support additional parameters for filtering and pagination:

Filtering by Name

Tools like get_dax_measures, get_dax_columns, get_schema and others support filtering by specific names:

# Get measures from a specific table get_dax_measures(table_name="Sales") # Get a specific measure get_dax_measures(table_name="Sales", measure_name="Total Sales")

Pagination for Large Tables

The get_table_contents tool supports pagination to handle large tables efficiently:

# Get first page of Customer table (default 20 rows per page) get_table_contents(table_name="Customer") # Get second page with 50 rows per page get_table_contents(table_name="Customer", page=2, page_size=50)

Development and Testing

Development Installation with uv

For developers working on the project:

Clone the repository (if not already done):
git clone https://github.com/username/pbixray-mcp.git cd pbixray-mcp
Install Python 3.13 (if needed):
uv python install 3.13
Create virtual environment with Python 3.13:
uv venv --python 3.13
Activate virtual environment:
.venv\Scripts\Activate.ps1
Install in development mode:
uv pip install -e .
Install dependencies:
uv pip install mcp pbixray numpy

Testing with Sample Files

The repository includes sample files and test scripts to help you get started:

With activated virtual environment:

# Make sure you're in the project directory and venv is activated cd "d:\AI\Guyen\pbixray-mcp-server-main" .venv\Scripts\Activate.ps1 # Test with sample AdventureWorks Sales.pbix file in demo/ folder python tests/test_with_sample.py # Try the interactive demo python examples/demo.py # For isolated tests of specific features python test_pagination.py python test_metadata_fix.py

With uv run (handles venv automatically):

# Test with sample AdventureWorks Sales.pbix file in demo/ folder uv run python tests/test_with_sample.py # Try the interactive demo uv run python examples/demo.py # For isolated tests of specific features uv run python test_pagination.py uv run python test_metadata_fix.py

Development Mode

To test the server during development, use the MCP Inspector:

With activated virtual environment:

# Navigate to project directory cd "d:\AI\Guyen\pbixray-mcp-server-main" # Activate virtual environment .venv\Scripts\Activate.ps1 # Run the MCP Inspector mcp dev src/pbixray_server.py

With uv run (handles venv automatically):

cd "d:\AI\Guyen\pbixray-mcp-server-main" uv run mcp dev src/pbixray_server.py

This starts an interactive session where you can call tools and test responses.

Alternative Installation Methods

Traditional pip Installation

You can also install PBIXRay MCP Server with pip:

pip install pbixray-mcp-server

For development with pip:

python -m venv venv venv\Scripts\activate pip install mcp pbixray numpy

WSL (Alternative)

If you prefer to use WSL, add the server configuration to your client configuration file:

{ "mcpServers": { "pbixray": { "command": "wsl.exe", "args": [ "bash", "-c", "source ~/dev/pbixray-mcp/venv/bin/activate && python ~/dev/pbixray-mcp/src/pbixray_server.py" ] } } }

WSL Path Conversion

When using the PBIXRay MCP Server in WSL with Claude Desktop on Windows, you need to be aware of path differences when loading PBIX files. Windows paths (like C:\Users\name\file.pbix) cannot be directly accessed in WSL. Instead, use WSL paths when referencing files:

Windows: C:\Users\name\Downloads\file.pbix
WSL: /mnt/c/Users/name/Downloads/file.pbix
