How to Set Up and Use Delphi Build Server
The Delphi Build Server is a TypeScript MCP server that enables AI agents to compile, build, and clean Delphi and Pascal projects on Windows without leaving the AI client. It supports Embarcadero RAD Studio projects (.dproj and .groupproj) via MSBuild, Free Pascal Compiler (FPC) source files, and Lazarus IDE projects via lazbuild — covering five distinct build tools in one server. Environment initialization is handled automatically through rsvars.bat for RAD Studio, ensuring the correct compiler paths are set before each build invocation.
Prerequisites
- Windows operating system (required for Delphi/MSBuild integration)
- Node.js 18 or higher and npm or pnpm
- Embarcadero RAD Studio installed (for delphi.build and delphi.clean tools)
- Free Pascal Compiler installed (for fpc.build tool, optional)
- Lazarus IDE installed (for lazarus.build and lazarus.clean tools, optional)
Clone the repository
Clone the mcp-delphi repository from GitHub.
git clone https://github.com/flydev-fr/mcp-delphi.git
cd mcp-delphiInstall dependencies and build
Install Node.js dependencies and compile the TypeScript source to JavaScript.
npm install && npm run build
# Or with pnpm:
pnpm install && pnpm run buildLocate your RAD Studio rsvars.bat
Find the rsvars.bat file for your RAD Studio version. This file initializes the Delphi build environment and is required for MSBuild-based compilation.
# Common path for RAD Studio 12 (Alexandria):
# C:\Program Files (x86)\Embarcadero\Studio\23.0\bin\rsvars.bat
# Adjust the version number to match your installation.Add to your MCP client configuration
Register the server in Claude Code or Claude Desktop with the required environment variables pointing to your RAD Studio installation.

}Prompts to try
Use these prompts in Claude after the Delphi Build Server is connected to compile and manage your Pascal projects.
- "Build MyApp.dproj in Release configuration for Win64 using the delphi.build tool"
- "Clean the MyApp.dproj build artifacts using delphi.clean"
- "Build the entire solution file MyGroup.groupproj for all projects in Release mode"
- "Compile src/main.pas with Free Pascal targeting Linux x86_64 using fpc.build"
- "Build MyLazarusProject.lpi using lazbuild in Release mode"
- "Show me the build output and any errors from the last delphi.build call"Troubleshooting Delphi Build Server
delphi.build fails with 'rsvars.bat not found' or environment initialization error
Set the RSVARS_BAT environment variable to the full path of your RAD Studio rsvars.bat. Example: C:\Program Files (x86)\Embarcadero\Studio\23.0\bin\rsvars.bat. The version number (23.0) corresponds to RAD Studio 12 Alexandria; adjust for your version.
MSBuild is not found during build
Set the MSBUILD_PATH environment variable to the full path of your MSBuild.exe. It is typically in the Visual Studio installation directory under MSBuild\Current\Bin\, or in C:\Windows\Microsoft.NET\Framework64\v4.0.30319\.
The server starts but no Delphi tools appear in Claude
Verify the dist/index.js file exists by running `npm run build` again. Check the MCP client logs for startup errors. On Windows, ensure the command path uses double backslashes or forward slashes in the JSON config.
