C++ Builder MCP Server

The C++ Builder MCP Server bridges the gap between AI assistants and native Windows development workflows by providing a programmatic interface for compiling C++ DLLs and inspecting their exported symbols. For developers who rely on AI tools to generate or refactor code, this server enables an end‑to‑end build cycle that can be triggered directly from the assistant’s prompt, eliminating manual command‑line steps and ensuring consistent build environments.

At its core, the server exposes two primary tools: and . The former invokes Visual Studio’s MSBuild engine to build a DLL from a given file, with optional configuration (Debug/Release), platform (x86/x64), and a module definition () file that controls which functions are exported. By integrating MSBuild, the server guarantees that all compiler options, preprocessor definitions, and project dependencies are respected exactly as they would be in a normal Visual Studio session. The output stream includes the full build log, making it easy for an AI assistant to surface warnings or errors back to the user in natural language.

The tool leverages to parse a compiled DLL and produce a detailed export table. The assistant can then query this table to verify that expected symbols are present, identify name mangling issues, or confirm that versioned exports match a specification. This capability is especially valuable when AI‑generated code must interoperate with existing native components, or when performing automated regression tests on binary interfaces.

Key features that distinguish this MCP server include:

• Configurable build settings: Developers can fine‑tune the build process directly from AI prompts, choosing debug or release configurations and targeting 32‑bit or 64‑bit platforms.
• Custom export control: By supplying a file, users dictate exactly which functions are exported, reducing accidental symbol leakage and simplifying versioning.
• Rich diagnostics: Full MSBuild logs and dumpbin output are returned to the AI, enabling contextual error handling and intelligent suggestions.
• Seamless integration: The server is designed to be added to an MCP configuration file, after which any AI client can invoke its tools with simple JSON payloads.

Typical use cases span from rapid prototyping—where an assistant writes a new library and immediately compiles it—to continuous integration pipelines that trigger builds on code changes, or even to security audits that automatically enumerate exported functions for vulnerability analysis. By abstracting the complexities of Visual Studio tooling behind a clean, declarative API, the C++ Builder MCP Server empowers developers to harness AI assistance without leaving their native development environment.
