MealMasteryAI Mcp Server

@mealmastery/mcp-server

MCP server for MealMastery AI meal planning. Integrates with Claude Desktop, VS Code Copilot, and other MCP-compatible AI agents.

Philosophy

The MCP server is a mirror of core capabilities, not a place where new features debut. Its value proposition is:

> "Everything you can do in the app, you can now do through natural conversation in Claude."

The MCP layer adds convenience (natural language) and composability (chaining tools), but the underlying capabilities exist in the core product first. New features should be built as API endpoints powering the web/mobile apps, then exposed through MCP -- never the other way around.

Setup

1. Get your API key from MealMastery Settings
2. Add to your Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "mealmastery": {
      "command": "npx",
      "args": ["-y", "@mealmastery/mcp-server"],
      "env": {
        "MEALMASTERY_API_KEY": "mm_live_..."
      }
    }
  }
}

Features

24 Tools

Full CRUD for meal planning, recipes, grocery lists, and user preferences -- plus AI generation with streaming progress.

3 Resources (read-only context)

| Resource URI | Description | |---|---| | mealmastery://meal-plan/current | Latest meal plan with all meals and nutrition | | mealmastery://user/preferences | Dietary preferences, allergies, skill level | | mealmastery://grocery-list/current | Grocery list for the current meal plan |

4 Prompt Templates (guided workflows)

| Prompt | Description | |---|---| | weekly-meal-prep | Full week planning: generate plan, review, grocery list, checkout | | swap-meal | Replace a meal in the current plan | | order-groceries | Preview and send grocery list to Instacart/Kroger | | quick-dinner | Single quick meal idea with time constraints |

Streaming & Progress

The generate_meal_plan tool supports MCP progress notifications. Clients that send a progressToken receive real-time updates during AI generation (0-100% progress with status messages). Clients without progress support gracefully fall back to the non-streaming endpoint.

Quota Awareness

API key quotas (daily request limits based on subscription tier) are reported on every token exchange. Free tier: 1,000 requests/day. Paid tier: 10,000 requests/day.
