#### Verify Installation:

1. Open GitHub Copilot Chat and switch to Agent mode
2. Type "@workspace /tools" to see available MCP tools
3. You should see tools from fabric-rti-mcp (SQL Lakehouse tools primarily)
4. Try a test query: "What tables are in my lakehouse?"

🔧 Alternative: Install from PyPI (Pip)

The Fabric RTI MCP Server is also available on PyPI:

#### From VS Code

1. Open command palette (Ctrl+Shift+P) and run MCP: Add Server
2. Select "Install from Pip"
3. Enter package name: microsoft-fabric-rti-mcp
4. Follow the prompts to configure

The process will add these settings to your settings.json:

🐛 Debugging the MCP Server locally

Assuming you have python installed and the repo cloned:

Install locally

pip install -e ".[dev]"

Configure

Follow the Manual Install instructions.

Attach the debugger

Use the Python: Attach configuration in your launch.json to attach to the running server. Once VS Code picks up the server and starts it, navigate to its output:

1. Open command palette (Ctrl+Shift+P) and run the command MCP: List Servers
2. Navigate to fabric-rti-mcp and select Show Output
3. Pick up the process ID (PID) of the server from the output
4. Run the Python: Attach configuration in your launch.json file, and paste the PID of the server in the prompt
5. The debugger will attach to the server process, and you can start debugging

🧪 Test the MCP Server

1. Open GitHub Copilot in VS Code and switch to Agent mode
2. You should see the Fabric RTI MCP Server in the list of tools
3. Try a prompt that tells the agent to use the Eventhouse tools, such as "List my Kusto tables"
4. The agent should be able to use the Fabric RTI MCP Server tools to complete your query

⚙️ Configuration

The MCP server can be configured using the following environment variables:

Required Environment Variables

Optional Environment Variables

Embedding Endpoint Configuration

The AZ_OPENAI_EMBEDDING_ENDPOINT is used by the semantic search functionality (e.g., kusto_get_shots function) to find similar query examples.

Format Requirements:

https://{your-openai-resource}.openai.azure.com/openai/deployments/{deployment-name}/embeddings?api-version={api-version};impersonate

Components:

• {your-openai-resource}: Your Azure OpenAI resource name
• {deployment-name}: Your text embedding deployment name (e.g., text-embedding-ada-002)
• {api-version}: API version (e.g., 2024-10-21, 2023-05-15)
• ;impersonate: Authentication method (you might use managed identity)

Authentication Requirements:

• Your Azure identity must have access to the OpenAI resource
• In case using managed identity, the OpenAI resource must should be configured to accept managed identity authentication
• The deployment must exist and be accessible

Configuration of Shots Table

The kusto_get_shots tool retrieves shots that are most similar to your prompt from the shots table. This function requires configuration of:

• Shots table: Should have an "EmbeddingText" (string) column containing the natural language prompt, "AugmentedText" (string) column containing the respective KQL, and "EmbeddingVector" (dynamic) column containing the embedding vector of the EmbeddingText.
• Azure OpenAI embedding endpoint: Used to create embedding vectors for your prompt. Note that this endpoint must use the same model that was used for creating the "EmbeddingVector" column in the shots table.

🔑 Authentication

The MCP Server uses Azure Identity via DefaultAzureCredential for secure, seamless authentication with automatic token caching to avoid repeated authentication prompts.

Authentication Methods (in priority order):

1. Environment Variables (EnvironmentCredential) - Perfect for CI/CD pipelines
2. Managed Identity (ManagedIdentityCredential) - For Azure-hosted deployments
3. Visual Studio Code (VisualStudioCodeCredential) - Uses your VS Code credentials
4. Azure CLI (AzureCliCredential) - ⭐ RECOMMENDED - Uses your existing Azure CLI login
5. Azure PowerShell (AzurePowerShellCredential) - Uses your Az PowerShell login
6. Azure Developer CLI (AzureDeveloperCliCredential) - Uses your azd login
7. Interactive Browser (InteractiveBrowserCredential) - Falls back to browser-based login if needed

🎯 Recommended Setup: Azure CLI (No repeated authentication prompts!)

The Azure CLI method provides the best user experience with automatic token caching:

#### Install Azure CLI:

Windows:

winget install Microsoft.AzureCLI

Or download from: https://aka.ms/installazurecliwindows

Mac:

brew install azure-cli

Linux:

curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash

#### Authenticate Once:

az login

That's it! The MCP server will automatically use these cached credentials for all queries. You'll never be prompted to authenticate again (unless the token expires, which is automatically refreshed).

How Token Caching Works

• First request: Authenticates using your preferred method (Azure CLI recommended)
• Subsequent requests: Automatically reuses the cached token
• Token expiration: Automatically refreshed in the background
• Zero prompts: Once authenticated, no more browser pop-ups or sign-in requests!

Alternative: Browser-Based Authentication

If you don't install Azure CLI, the server will fall back to interactive browser authentication:

• First query opens a browser for sign-in
• Token is cached for the session
• May require occasional re-authentication

For the smoothest experience, we strongly recommend using Azure CLI!

HTTP Mode Configuration for MCP Server

When the MCP server is running locally to the agent in HTTP mode or is deployed to Azure, the following environment variables are used to define and enable HTTP mode. You can find practical examples of this setup in the tests/live/test_kusto_tools_live_http.py file:

HTTP clients connecting to the server need to include the appropriate authentication token in the request headers:

# Example from test_kusto_tools_live_http.py
auth_header = f"Bearer {token.token}"

headers = {
    "Content-Type": "application/json",
    "Accept": "application/json, text/event-stream",
    "Authorization": auth_header,
}

OBO Flow Authentication

If your scenario involves a user token with a non-Kusto audience and you need to exchange it for a Kusto audience token using the OBO flow, the Fabric RTI MCP Server can handle this exchange automatically by setting the following environment variables:

This flow is typically used in OAuth scenarios where a gateway like Azure API Management (APIM) is involved (example: https://github.com/ai-microsoft/adsmcp-apim-dual-validation?tab=readme-ov-file). The user authenticates via Entra ID, and APIM forwards the token to the MCP server. The token audience is not Kusto, so the MCP server must perform an OBO token exchange to get a token with the Kusto audience. To support this setup, your Microsoft Entra App must be configured to use Federated Credentials following the official guide: https://learn.microsoft.com/en-us/entra/workload-id/workload-identity-federation. This enables the app to exchange tokens (OBO). Additionally, the Entra app must be granted Azure Data Explorer API permissions to successfully acquire an OBO token with the Kusto audience.

Remote Deployment

The MCP server can be deployed using the method of your choice. For example, you can follow the guide at https://github.com/Azure-Samples/mcp-sdk-functions-hosting-python/blob/main/ExistingServer.md to deploy the MCP server to an Azure Function App.

🛡️ Security Note

Your credentials are always handled securely through the official Azure Identity SDK - we never store or manage tokens directly.

MCP as a phenomenon is very novel and cutting-edge. As with all new technology standards, consider doing a security review to ensure any systems that integrate with MCP servers follow all regulations and standards your system is expected to adhere to. This includes not only the Azure MCP Server, but any MCP client/agent that you choose to implement down to the model provider.
