# CalorieLog Pro > A calorie tracker that works with ChatGPT and Claude. Users say what they ate or show a photo of a meal, > a receipt or a handwritten list, and their AI assistant logs every item with calories and macros. CalorieLog Pro is a calorie and nutrition diary at https://calorielogpro.com. It has a remote MCP server (OAuth 2.1) so AI apps can read and write the signed-in user's own diary: entries by meal, calories, protein, carbs, fat, custom foods with nicknames, a daily goal, and day and date-range summaries. ## Connect - MCP server: https://calorielogpro.com/mcp (Streamable HTTP, OAuth 2.1 with DCR and CIMD) - [How to connect Claude or ChatGPT, and the tool list](https://calorielogpro.com/docs/mcp) - [Developer notes](https://calorielogpro.com/docs/mcp.md) ## Policies - [Privacy policy](https://calorielogpro.com/privacy) · [Terms](https://calorielogpro.com/terms) · [Support](https://calorielogpro.com/support) ## Related - WorkoutLog Pro (training log): https://workoutlogpro.com/llms.txt - HabitLog Pro (habit tracker): https://habitlogpro.com/llms.txt
