Use with your AI

Kition ships an MCP server for its kits. Run it over stdio against a folder, without the app open, and your agent gets tools like sheet_inspect, sheet_run and sheet_check for every kit.

# Claude Code
claude mcp add kition -- kition-kits-mcp --workspace /path/to/your/folder

# Any MCP client (mcpServers config)
{
  "mcpServers": {
    "kition": {
      "command": "kition-kits-mcp",
      "args": ["--workspace", "/path/to/your/folder"]
    }
  }
}

The kition-kits-mcp binary comes with Kition. Without a licence key it runs in development and evaluation mode.
