How to run

Genetic Algorithm

There's already a sample problem loaded in genetic-mcp-server/genetic_algorithm/main.py. To run it, run the following commands:

cd genetic-mcp-server/genetic_algorithm
python3 main.py

There are also sample problems in genetic-mcp-server/genetic_algorithm/samples. To run them, simply replace <problem> below with the name of the actual problem you want to run:

cd genetic-mcp-server/genetic_algorithm
python3 main.py samples/<problem>.json

If you want to run your own problems, you have 2 options:

  1. Simply modify the following section of genetic-mcp-server/genetic_algorithm/main.py:
tsp_data = {
            "options": {
                "population_size": 100,
                "chromosome_size": 4,
                "fitness_function": {
                    "cities": ["A", "B", "C", "D"],
                    "distance_matrix": [
                        [0, 10, 15, 20],
                        [10, 0, 35, 25],
                        [15, 35, 0, 30],
                        [20, 25, 30, 0]
                    ]
                }
            },
            "problem": "traveling_salesman",
            "generations": 50
}
  1. Create a .json file in the same style of the ones in genetic-mcp-server/genetic_algorithm/samples and replace <path_to_your_file> with the path to your file:
cd genetic-mcp-server/genetic_algorithm
python3 <path_to_your_file>

MCP Server

If you want to run the MCP server, run:

cd genetic-mcp-server
uv run main.py

How to add the MCP server to Cursor

Replace <full-path-to-genetic-mcp-server> in the following JSON with your actual path:

{
    "mcpServers": {
        "genetic_algorithm_mcp_server": {
            "command": "uv",
            "args": [
                "--directory",
                <full-path-to-genetic-mcp-server>,
                "run",
                "main.py"
            ]
        }
    }
}
