01 · Install Styx MCP Server

before you install - you'll need

STYX_API_KEY

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add timmx7-styx -- npx -y styx-mcp-server

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "timmx7-styx": {
      "command": "npx",
      "args": [
        "-y",
        "styx-mcp-server"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
