  "mcpServers": {
    "etsy": {
      "command": "node",
      "args": ["/path/to/etsy-mcp/dist/index.js"],
      "env": {
        "ETSY_API_KEY": "your_keystring",

Authentication

On first use, call the authenticate tool. This opens your browser to Etsy's OAuth consent page using PKCE. After granting access, tokens are stored at ~/.etsy-mcp/tokens.json (owner-only permissions) and auto-refreshed when they expire.
