How to Set Up and Use MCP XPP
MCP XPP is an experimental Model Context Protocol server for Microsoft Dynamics 365 Finance & Operations X++ development that gives AI assistants the ability to create, inspect, modify, and delete D365 objects like classes, tables, enums, and forms directly through natural language. It integrates with Visual Studio 2022 and reads your PackagesLocalDirectory to understand the existing codebase, enabling intelligent navigation and batch modification of X++ objects. Teams building D365 customizations can use it to speed up repetitive scaffolding and code exploration tasks inside AI coding tools.
Prerequisites
- Node.js 18 or later
- Microsoft Dynamics 365 Finance & Operations development environment with Visual Studio 2022
- A local PackagesLocalDirectory from a D365 F&O installation
- Git and npm to clone and build the server
- An MCP-compatible client such as Claude Desktop or VS Code with MCP support
Clone the repository and install dependencies
Clone the mcp_xpp repository and install the Node.js dependencies.
git clone https://github.com/ccampora/mcp_xpp.git
cd mcp_xpp
npm installBuild the server
Run the build script to compile the TypeScript source to the build/ directory.
.\tools\build-and-run.ps1 -Action buildLocate your PackagesLocalDirectory
Find the path to your D365 F&O PackagesLocalDirectory. This is typically at C:\AOSService\PackagesLocalDirectory or similar. You will pass this path when starting the server.
Start the MCP server
Run the server with the path to your PackagesLocalDirectory. The server will index D365 objects from this location.
node build/index.js --xpp-path "C:\AOSService\PackagesLocalDirectory"Configure Claude Desktop
Add the server to your claude_desktop_config.json using the absolute path to the built index.js.
MCP XPP Examples
Client configuration
Add this block to your claude_desktop_config.json, replacing the path with the actual location of your cloned and built mcp_xpp.

}Prompts to try
Once connected, use these prompts to navigate and modify your D365 X++ codebase.
- "Create a new AxTable called CustomerSegment in the usr layer"
- "Search for all tables matching the pattern Cust* and list their names"
- "Inspect the CustTable object and show me its fields"
- "Add a string field called CustomerCategory to CustTable"
- "List all available form patterns I can use when creating a new form"Troubleshooting MCP XPP
Server fails to start or throws an error about xpp-path
Ensure you pass the --xpp-path argument pointing to a valid PackagesLocalDirectory. The path must exist and contain D365 package folders.
build/index.js not found after setup
Run the build step (.\tools\build-and-run.ps1 -Action build) in a PowerShell terminal. Ensure Node.js and npm are in your PATH and that npm install completed without errors.
Object creation fails with dependency errors
Use the discover_modification_capabilities tool first to check what modifications are supported for the target object type, then use execute_object_modification for batch changes.
