How to Set Up and Use Minecraft Server
MCppServer is a high-performance Minecraft server implementation written in C++ that targets vanilla-compatible gameplay with significantly better CPU and memory efficiency than the reference Java server. It is designed for developers and server operators who want to host Minecraft 1.21.1 Java Edition clients on minimal hardware, and it exposes an experimental AI-agent integration layer via the Model Context Protocol. This makes it possible for AI tools to query server state, manage players, and automate administrative tasks.
Prerequisites
- A C++20-capable compiler: GCC 11+ or Clang 13+ on Linux, MinGW-w64 on Windows
- CMake 3.14 or later and either Make or Ninja build system
- Git for cloning the repository
- A Minecraft Java Edition client (version 1.21.1) for connecting to the server
- An MCP-compatible AI client (e.g. Claude Desktop) if using the MCP integration layer
Clone the repository
Pull the source code from GitHub. The project has no pre-built binaries, so you must compile from source.
git clone https://github.com/Noeli14/MCppServer.git
cd MCppServerCreate a build directory and run CMake
Configure the build in Release mode for best performance. Use Debug mode if you are contributing or diagnosing issues.
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=ReleaseCompile the server
Build with make or ninja. On a modern machine this takes one to three minutes.
# With Make
make -j$(nproc)
# With Ninja
ninjaRun the server
Launch the compiled binary. On first run it will generate a world and default configuration files in the working directory.
./MCppServerConfigure MCP client access
If you want AI tools to interact with the running server, add the MCP server entry to your client config. The server communicates over stdio.
{
"mcpServers": {
"mcppserver": {
"command": "./MCppServer",
"args": []
}
}
}Disable online mode if authentication issues arise on Linux
Linux builds may have issues with Mojang authentication. Edit server.properties and set online-mode=false for LAN or private testing environments.
# In server.properties
online-mode=falseMinecraft Server Examples
Client configuration
Connect an MCP client to a locally compiled and running MCppServer binary.
{
"mcpServers": {
"mcppserver": {
"command": "/path/to/MCppServer/build/MCppServer",
"args": []
}
}
}Prompts to try
Use AI tools to query and manage the Minecraft server via the MCP integration.
- "List all currently connected players on the Minecraft server"
- "Show me the current server status and TPS"
- "Broadcast a message to all players: Server will restart in 5 minutes"
- "What chunks are currently loaded?"
- "Show the server console log for the last 50 lines"Troubleshooting Minecraft Server
Build fails with C++20 feature errors
Ensure you have GCC 11+ or Clang 13+ installed. On Ubuntu, run: sudo apt install g++-12 and re-run cmake with -DCMAKE_CXX_COMPILER=g++-12.
Minecraft client cannot connect
Check that the server is bound to 0.0.0.0 (not only 127.0.0.1) in its config, and that firewall rules allow TCP port 25565. For local LAN testing, disable online mode.
Server crashes on chunk generation
This is a known early-development issue. The project is in active development — check the GitHub Issues page for the latest workarounds and update to the newest commit.
