@sommelierx/mcp-server

Wine pairing intelligence for AI assistants. Connect Claude, Cursor, Windsurf, or any MCP-compatible client to a sommelier-grade pairing algorithm that matches wines to your ingredients, dishes, and recipes.

Quick Start

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "sommelierx": {
      "command": "npx",
      "args": ["@sommelierx/mcp-server"]
    }
  }
}

That is it. Ask Claude "What wine goes with grilled salmon?" and it will use SommelierX to answer.

With a Pro API key

For recipe extraction, group pairing, and score breakdowns:

{
  "mcpServers": {
    "sommelierx": {
      "command": "npx",
      "args": ["@sommelierx/mcp-server"],
      "env": {
        "SOMMELIERX_API_KEY": "sk_live_your_key_here"
      }
    }
  }
}

Cursor / Windsurf / Other MCP Clients

The same configuration works. Add the command and args to your client's MCP settings.

Available Tools

| Tool | What it does | Tier | |------|-------------|------| | pair_wine_with_ingredients | Find wines for a list of ingredients (e.g. "salmon, lemon, dill") | Free | | pair_wine_with_meal | Find wines for a dish name (e.g. "risotto ai funghi") | Free | | find_meals_for_wine | Find dishes that pair with a wine style (e.g. "Barolo") | Free | | search_ingredients | Search the ingredient database | Free | | search_meals | Search the meal database | Free | | pair_wine_with_recipe_url | Extract ingredients from a recipe URL and pair wines | Pro | | group_pairing | Find the best wine across multiple dishes (e.g. 3-course dinner) | Pro |

Authentication

SommelierX supports two authentication methods. You can use either one -- no need to configure both.

Option 1: API Key (subscription)

Set the SOMMELIERX_API_KEY environment variable in your MCP client config. The key format is sk_live_.... You get a monthly call allowance based on your tier (Free / Pro / Enterprise).

{
  "mcpServers": {
    "sommelierx": {
      "command": "npx",
      "args": ["@sommelierx/mcp-server"],
      "env": {
        "SOMMELIERX_API_KEY": "sk_live_your_key_here"
      }
    }
  }
}

Option 2: x402 Payment (pay per call)

No API key needed. Your AI agent pays per call using USDC on the Base network via the Coinbase x402 protocol. When a request lacks an API key, the server returns a 402 Payment Required response with a payment payload. x402-compatible agents handle this automatically.

This is ideal for:

• AI agents that manage their own wallet
• Pay-as-you-go usage without a subscription
• Agent-to-agent commerce (no human in the loop)

Pricing (per call)

| Tool | Price | Tier | |------|-------|------| | pair_wine_with_meal | $0.01 | Free | | find_meals_for_wine | $0.01 | Free | | search_ingredients | $0.005 | Free | | search_meals | $0.005 | Free | | pair_wine_with_ingredients | $0.02 | Pro | | pair_wine_with_recipe_url | $0.02 | Pro | | group_pairing | $0.03 | Pro |

With an API key, calls are deducted from your tier allowance. With x402, each call is charged at the listed price.

Example Conversations

Basic pairing:

"What wine pairs well with salmon, asparagus, and hollandaise sauce?"

Reverse pairing:

"I have a bottle of Barolo. What should I cook?"

Recipe URL:

"What wine goes with this recipe? https://www.allrecipes.com/recipe/..."

Dinner party:

"I'm planning a 3-course dinner: Caesar salad, rack of lamb, and chocolate mousse. What single wine works for all courses?"

How It Works

1. You ask your AI assistant a wine question
2. The assistant calls the appropriate SommelierX tool
3. The MCP server translates your input into structured API calls
4. SommelierX's pairing algorithm (17 food DNA dimensions x 19 wine DNA dimensions) calculates matches
5. You get scored wine recommendations based on real sommelier expertise

Ingredient Resolution

When you use pair_wine_with_ingredients, the server automatically resolves natural language ingredient names to database entries. The AI assistant does not need to know database IDs -- it passes ingredient names directly.

Configuration
