概览

What is Godbolt Compiler Explorer?

Godbolt Compiler Explorer is an MCP (Model Context Protocol) server that integrates with the Compiler Explorer service (godbolt.org). It allows MCP-compatible agents to compile source code, format code, and retrieve information about supported languages, compilers, libraries, and assembly instructions.

How to use Godbolt Compiler Explorer?

Clone the repository, create and activate a Python virtual environment, and install dependencies from requirements.txt. Run the server standalone with python godbolt_mcp.py, or add it to an MCP-compatible agent by specifying the virtual environment's Python interpreter and the path to godbolt_mcp.py in the MCP configuration JSON.

Key features of Godbolt Compiler Explorer

Compile source code with user arguments, files, and libraries
Compile CMake projects with compiler and library options
Format source code using available code formatters
List all supported programming languages
Get available compilers and libraries per language
Retrieve assembly instruction documentation for any opcode

Use cases of Godbolt Compiler Explorer

Compile a C++ file with a specific GCC version and optimization level, then examine the generated assembly
Compile a Rust program with the latest Rust compiler and release optimizations
Automate code formatting across supported languages within agent workflows
Query available compilers for a language to choose the best toolchain for a task

常见问题

What compilers and languages are supported?

The server provides resources to list all supported languages (`resource://languages`) and available compilers for a given language (`resource://compilers/{language_id}`).

How do I install and configure the server?

Clone the repository, set up a Python virtual environment, install dependencies, then run the server or add it to your MCP configuration with the absolute paths to the virtual environment Python and the script.

What dependencies are required?

The server requires `fastmcp>=0.2.0` for the MCP framework and `httpx>=0.25.0` for HTTP requests.

Can I use it without an MCP agent?

Yes. The server can be run standalone using `python godbolt_mcp.py`, which starts it as a local MCP server.

Does it support CMake projects?

Yes. The `compile_cmake` tool accepts compiler ID, source, optional arguments, files, and libraries to compile CMake-based code.
