# HabitLog Pro > A habit tracker that works with ChatGPT and Claude. Users say what they did and skipped and their AI > assistant checks in every habit at once, amounts included. HabitLog Pro is a daily habit tracker at https://habitlogpro.com. It has a remote MCP server (OAuth 2.1) so AI apps can read and write the signed-in user's own habits: check-ins (done, skipped, counts, caffeine, drinks), habits with schedules and nicknames, streaks and date-range summaries. ## Connect - MCP server: https://habitlogpro.com/mcp (Streamable HTTP, OAuth 2.1 with DCR and CIMD) - [How to connect Claude or ChatGPT, and the tool list](https://habitlogpro.com/docs/mcp) - [Developer notes](https://habitlogpro.com/docs/mcp.md) ## Policies - [Privacy policy](https://habitlogpro.com/privacy) · [Terms](https://habitlogpro.com/terms) · [Support](https://habitlogpro.com/support) ## Related - CalorieLog Pro (calorie diary): https://calorielogpro.com/llms.txt - WorkoutLog Pro (training log): https://workoutlogpro.com/llms.txt
