Linux
Install Python using your package manager (e.g., sudo apt install python3 python3-venv python3-pip).
Open Command Palette (Ctrl+Shift+P), type LGEDV: Install MCP Server and select the command.
The extension will open a terminal and run the Bash script install_mcp.sh to install MCP server in ~/mcp_server (default).
After installation, you will see a success notification and a sample configuration file .vscode/mcp.json created in your project folder.
If you need to adjust the path for CPP_DIR or CUSTOM_RULE_PATH, edit the .vscode/mcp.json file to match your project.
MCP Server Configuration
Create .vscode/mcp.json in your project codebase with the following format (Window sample)
{
"servers": {
"lgedv": {
"command": "C:\\Program Files\\MCP Server CodeGuard\\venv\\Scripts\\codeguard.exe",
"args": ["--transport", "stdio"],
"env": {
"CPP_DIR": "C:\\path\\to\\source_code", // change this line
"CUSTOM_RULE_PATH": "C:\\path\\to\\CustomRule.md" // change this line
}
}
}
}
CPP_DIR: Path to the folder containing C++ files to be analyzed (memory leak, resource leak, race condition).
e.g. "CPP_DIR": "D:\src\codefun\code_test"
CUSTOM_RULE_PATH: Path to the custom rule file defined by the user, used for the check_custom prompt.
e.g. "CUSTOM_RULE_PATH": "C:\path\to\CustomRule.md"
Open mcp.json on vscode and start MCP server by click start button.
