C++ Builder MCP Server

An MCP server providing C++ DLL compilation and analysis capabilities. This server enables building C++ DLLs with specific export settings and analyzing DLL exports using Visual Studio build tools.

Features

• C++ DLL compilation with MSBuild
• Custom export settings via .def files
• DLL export analysis using dumpbin
• Configurable build settings
• Platform and configuration targeting
• Detailed build output

Tools

DLL Compilation

compile_dll

Compile a C++ DLL with specific export settings using MSBuild.

• projectPath: Path to the .vcxproj file (required)
• configuration: Build configuration (optional)
  • Values: 'Debug' or 'Release'
  • Default: 'Release'
• platform: Target platform (optional)
  • Values: 'x86' or 'x64'
  • Default: 'x86'
• defFile: Path to .def file for exports (optional)
  • Specifies exported functions and their attributes
  • Used to control which functions are exposed by the DLL

The tool uses Visual Studio's MSBuild to compile the DLL, providing:

• Full build output with warnings and errors
• Support for different configurations and platforms
• Module definition file integration
• Detailed build logs

Export Analysis

analyze_exports

Analyze exports from a compiled DLL using dumpbin.

• dllPath: Path to the DLL file (required)

The analysis provides:

• List of all exported functions
• Export ordinals
• Function names and addresses
• Export forwarding information
• Detailed export table analysis

Requirements

• Visual Studio 2022 Community Edition or higher
• Visual C++ build tools
• Windows SDK

});

// Compilation with specific settings
await mcp.use("cpp-builder", "compile_dll", {
  projectPath: "./src/MyLibrary.vcxproj",
  configuration: "Debug",
  platform: "x64",
  defFile: "./src/exports.def"
});

Analyze DLL Exports

await mcp.use("cpp-builder", "analyze_exports", {
  dllPath: "./bin/Release/MyLibrary.dll"
});
