01 · Install Arcane RMCP

before you install - you'll need

Set RARCANE_API_URL, RARCANE_API_KEY, RARCANE_MCP_HOST before connecting.

Claude Code

claude mcp add jmagar-arcane-rmcp -- npx -y arcane-rmcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "jmagar-arcane-rmcp": {
      "command": "npx",
      "args": [
        "-y",
        "arcane-rmcp"
      ]
    }
  }
}

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

Using another client? Same JSON, different key
