Frequently Asked Questions

What is Nutrition MCP?

Nutrition MCP is a free Model Context Protocol (MCP) server that lets you track meals, calories, macros, and nutrition history through natural conversation with Claude AI. Instead of manually entering data into a traditional app, you simply tell Claude what you ate and it logs everything for you.

How does AI meal tracking work?

Once you connect Nutrition MCP to Claude, you can describe your meals in plain language — for example, "I had a chicken salad with avocado for lunch." Claude estimates the calories, protein, carbs, and fat, then logs the meal to your personal nutrition history. You can ask for daily or weekly summaries, edit past meals, or track trends over time.

Is Nutrition MCP free?

Yes, Nutrition MCP is completely free to use. There are no premium tiers, ads, or hidden costs. You just need a Claude account to connect.

Which Claude clients are supported?

Nutrition MCP works with Claude.ai, the Claude desktop app (macOS and Windows), and the Claude mobile apps for iOS and Android. It also works with any MCP-compatible client that supports OAuth 2.0 with PKCE, including Cursor, Windsurf, and Claude Code.

What is the Model Context Protocol (MCP)?

The Model Context Protocol is an open standard that allows AI assistants like Claude to connect to external tools and data sources. MCP servers provide specific capabilities — in this case, nutrition tracking — that the AI can use during conversation. Think of it as a plugin system for AI assistants.

What nutrition data can I track?

You can track calories, protein, carbohydrates, fat, and fiber for every meal. Claude estimates nutritional values based on your meal descriptions. You can view daily summaries, query meals by date range, update or delete past entries, and monitor your intake trends over time.

Is my nutrition data private?

Your meal data is stored securely and linked to your personal account. Only you can access your nutrition history through your authenticated Claude session. Nutrition MCP does not sell or share your data. You can delete your account and all associated data at any time.
