{
  "mcpServers": {
    "simmer-sdk": {
      "command": "npx",
      "args": [
        "-y",
        "[email protected]"
      ],
      "env": {
        "SIMMER_API_KEY": "<YOUR_VALUE>",
        "SIMMER_MCP_ALLOW_LIVE": "<YOUR_VALUE>"
      }
    }
  }
}

SIMMER_API_KEY secret — Simmer API key (sk_live_...) from simmer.markets/dashboard. Required for Pro tools (autoresearch, trading, briefings). Free tools work without it.
SIMMER_MCP_ALLOW_LIVE — Set to 'true' to allow live trading via simmer_trade. Without this, all trades run in paper/sim mode.
