The Forgetting Curve Calculator is a mathematical engine designed to help learners master long-term retention. Based on the principles of the Ebbinghaus Forgetting Curve, this MCP server provides tools to track how information decays over time and when you should intervene with review sessions. Use get_current_retention to see your current memory strength, predict_decay_thresholds to identify upcoming critical drop-off points (70%, 50%, and 20%), and estimate_maintenance_effort to plan the number of future reviews needed for long-term stability. It acts as a bridge between your learning data and AI agents like Cursor, Claude Desktop, and Windsurf, allowing you to automate your study scheduling.

I studied biology on 2024-05-01. I have done 2 reviews with a 7-day interval. What is my current retention?

Your current memory retention for biology is 85%.

Based on my study date of 2024-06-10, 3 revisions, and a 5-day interval, when will my retention drop below 70%?

Your retention is predicted to drop below the 70% threshold in approximately 4 days.

I want to maintain a 90% retention for my history topic. I currently have 75% retention with a 10-day interval. How many more reviews do I need?

You will need approximately 3 more review sessions to reach and maintain your target of 90% retention.

The `get_current_retention` tool uses your initial study date, the number of completed revisions, and the interval between them to calculate the current percentage of memory strength based on the Ebbinghaus decay model.
