Usage
Docker (Recommended)
The easiest way to run chess-mcp with Claude Desktop is using Docker. If you don't have Docker installed, you can get it from Docker's official website.
Edit your Claude Desktop config file:
- Mac:
~/Library/Application Support/Claude/claude_desktop_config.json - Windows:
%APPDATA%/Claude/claude_desktop_config.json - Linux:
~/.config/Claude/claude_desktop_config.json
Then add the following configuration:
{
"mcpServers": {
"chess": {
"command": "docker",
"args": [
"run",
"--rm",
"-i",
"pab1it0/chess-mcp"
]
}
}
}Running with UV
Alternatively, you can run the server directly using UV. Edit your Claude Desktop config file (locations listed above) and add the server configuration:
{
"mcpServers": {
"chess": {
"command": "uv",
"args": [
"--directory",
"",
"run",
"src/chess_mcp/main.py"
]
}
}
}
