simmer-mcp (Python) — DEPRECATED

⚠️ This Python package is deprecated. The Simmer MCP server has moved to npm.

Migrate

Uninstall the Python package and install the npm one:

pip uninstall simmer-mcp
npm install -g simmer-mcp

Then update your agent config from:

{
  "mcpServers": {
    "simmer": {
      "command": "python",
      "args": ["-m", "simmer_mcp"]
    }
  }
}

to:

{
  "mcpServers": {
    "simmer": {
      "command": "npx",
      "args": ["-y", "simmer-mcp"],
      "env": {
        "SIMMER_API_KEY": "sk_live_..."
      }
    }
  }
}

The npm package includes all previous functionality (docs, error troubleshooting) plus skill discovery, skill execution, experiment tracking, and AI market tools.
