Microsoft Fabric MCP Server .NET Tool

A local-first Model Context Protocol (MCP) server that provides AI agents with comprehensive access to Microsoft Fabric's public APIs, item definitions, and best practices. The Fabric MCP Server packages complete OpenAPI specifications into a single context layer for AI-assisted development—without connecting to live Fabric environments.

Overview

Microsoft Fabric MCP Server gives your AI agents the knowledge they need to generate robust, production-ready code for Microsoft Fabric—all without directly accessing your environment.

Key capabilities:

• Complete API Context: Full OpenAPI specifications for all supported Fabric workloads
• Item Definition Knowledge: JSON schemas for every Fabric item type (Lakehouses, pipelines, semantic models, notebooks, etc.)
• Built-in Best Practices: Embedded guidance on pagination, error handling, and recommended patterns
• Local-First Security: Runs entirely on your machine—never connects to your Fabric environment

Installation

• You must have .NET 9 SDK or later installed. To verify the .NET version, run: dotnet --version

• Clone and build the repository:

  git clone https://github.com/microsoft/mcp.git
  cd mcp
  dotnet build servers/Fabric.Mcp.Server/src/Fabric.Mcp.Server.csproj --configuration Release
  

• Configure the mcp.json file with the following:

  {
      "mcpServers": {
          "Fabric MCP Server": {
              "command": "/path/to/repo/servers/Fabric.Mcp.Server/src/bin/Release/fabmcp",
              "args": [
                  "server",
                  "start"
              ],
              "type": "stdio"
          }
      }
  }
  

Platform Notes:

• macOS/Linux: Use the path as-is
• Windows: Use backslashes and add .exe extension: C:\path\to\repo\servers\Fabric.Mcp.Server\src\bin\Release\fabmcp.exe

Usage

Getting Started

1. Open GitHub Copilot in VS Code and switch to Agent mode.
2. Click refresh on the tools list
   • You should see the Fabric MCP Server in the list of tools
3. Try a prompt that uses Fabric context, such as What Fabric workload types are available?
   • The agent should be able to use the Fabric MCP Server tools to complete your query
4. Check out the Microsoft Fabric documentation and review the troubleshooting guide for commonly asked questions
5. We're building this in the open. Your feedback is much appreciated!
   • 👉 Open an issue in the public repository

What can you do with the Fabric MCP Server?

✨ The Fabric MCP Server supercharges your agents with Microsoft Fabric context. Here are some prompts you can try:

📊 Fabric Workloads & APIs

• "What are the available Fabric workload types I can work with?"
• "Show me the OpenAPI operations for 'notebook' and give a sample creation body"
• "Get the platform-level API specifications for Microsoft Fabric"
• "List all supported Fabric item types"

🏗️ Resource Definitions & Schemas

• "Create a Lakehouse resource definition with a schema that enforces a string column and a datetime column"
• "Show me the JSON schema for a Data Pipeline item definition"
• "Generate a Semantic Model configuration with sample measures"
• "What properties are required for creating a KQL Database?"

📝 Best Practices & Examples

• "Show me best practices for handling API throttling in Fabric"
• "How should I implement retry logic for Fabric API rate limits?"
• "List recommended retry/backoff behavior for Fabric APIs when rate-limited"
• "Show me best practices for authenticating with Fabric APIs"
• "Get example request/response payloads for creating a Notebook"
• "What are the pagination patterns for Fabric REST APIs?"

🔧 Development Workflows

• "Generate a data pipeline configuration with sample data sources"
• "Help me scaffold a Fabric workspace with Lakehouse and notebooks"
• "Show me how to handle long-running operations in Fabric APIs"
• "What's the recommended error handling pattern for Fabric API calls?"

Available Tools

The Fabric MCP Server exposes the following tools for AI agents:

Always verify available commands via --help. Command names and availability may change between releases.

OneLake (onelake)

All commands accept either GUID identifiers (--workspace-id, --item-id) or friendly names (--workspace, --item), with the exception of onelake item create, which currently requires GUID identifiers. Friendly-name items must be provided as <itemName>.<itemType> (for example, SalesLakehouse.lakehouse). Table commands also accept the schema via --namespace or its alias --schema. Use dotnet run -- onelake --help (or fabmcp onelake --help for published builds) to inspect the complete option set before scripting.

Security

The Fabric MCP Server is a local-first tool that runs entirely on your machine. It provides API specifications, schemas, and best practices without connecting to live Microsoft Fabric environments.

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.
