A MCP server project - To be shown to Aurora (BIM Engine)

This project implements a simple application to test SDK for .Net to create a MCP Server, to be used by Claude, Copilot or another LLM. The idea of this test is to have a screenshot of a running program (in this case Firefox browser) using Windows API, then apply an OCR to recognize a text (in this case, the domain in the address bar).

• C# / .Net 8
• ModelContextProtocol - Repository here
• Tesseract and Tessdata - Repository here

Used Techniques

• Clean architecture
• Clean code
• Static and instanced classes
• Handling exceptions
• Dependencies injection

How to Install

• Install Visual Studio 2022 Community Edition and .Net 8 in your computer.
• Install Claude Desktop.
• Install Firefox Browser.
• Create a new directory in C:\ -> C:\revit-mcp-server. It will be the workspace for this project. Make sure to be there in your terminal.
• Create a new directories inside the workspace, named captures, app and tessdata. Make sure to have permissions to write in all directories that you created.
• In captures directory all screenshots will be saved.
• Clone this repository directly to app: git clone https://github.com/sergiomauz/mcp-server-dotnet-bimengine.git app
• Clone tessdata repository directly to tessdata: git clone https://github.com/tesseract-ocr/tessdata.git tessdata
• Finally, click in Build Solution (F6) to make sure that you will have the an .exe file to be used by Claude; if there are no errors, you did it very well.

How to Use

There are 2 ways to use this application: As a console application and as a MCP Server.

To be used as a console application:

• Open a Firefox window (install it if you don't have it) and navigate to any website. In this case BIM-Engine

• In VS 2022, open program.cs file, comment region "REVIT-MCP-SERVER" and uncomment region "CONSOLE-APPLICATION".

• Run application (F5), wait until application is ready:

• Put the Firefox window and the website in the foreground to continue, wait 2 seconds and application will show a message with the domain that it detected:

• In the directory C:\revit-mcp-server\captures you can see 2 new files: A screenshot of Firefox and a cropped image focused in the address bar:

• If you don't put any Firefox window in foreground after 10 seconds, the application will send a message and terminate.

To be used as a MCP server:

• Open a Firefox window (install it if you don't have it) and navigate to any website. In this case BIM-Engine

• In VS 2022, open program.cs file, uncomment region "REVIT-MCP-SERVER" and comment region "CONSOLE-APPLICATION".

• Run application (F5) and wait until application is ready, if all is ok without errors and exceptions, you can stop it:

• In your file explorer, go to %APPDATA%\Claude, find the file claude_desktop_config.json to edit. Add the configuration to run a new MCP Server using the content of claude_desktop_config.json (the other one in C:\revit-mcp-server\app dire
