What is Anneal MCP?

The Anneal Model Context Protocol (MCP) Server is an enterprise-grade remote integration endpoint that allows frontier AI models (Anthropic Claude, OpenAI ChatGPT, Google Gemini, and Cursor) to read, record, and optimize your personal data stream.

Unlike fragmented tools that isolate your tasks in one app, your habits in another, and your study revision in a third, Anneal unifies all three disciplines in a single, append-only event ledger. Through this server, AI agents act directly on your behalf:

1. Habits Engine: Query adherence, log completions, calculate streaks, and project behavioral velocity.
2. Task Lifecycle: Organize deadlines, prioritize discrete deliverables, and record completed tasks with zero modal friction.
3. Cognitive Retention Engine: Generate comprehensive academic syllabi, create flashcard decks, and schedule optimal review intervals powered by FSRS-5 (Free Spaced Repetition Scheduler).

AI Agent Prompt Cookbook

Copy and paste these verified interaction recipes into Claude, ChatGPT, or Gemini:

Scenario 1: Habit Tracking & Reflection

"Inspect my Anneal habits for the past 14 days. Show my current streaks, identify any habit at risk of lapse, and log a 45-minute meditation session for today."

Scenario 2: FSRS-5 Spaced Repetition Review

"Check Anneal for all flashcards due for review today in my 'Machine Learning' deck. Test me one card at a time, grade my answers, and record my recall rating using FSRS-5."

Scenario 3: Automated Syllabus Generation

"I need to master Linear Algebra in 6 weeks. Generate a structured syllabus in Anneal with daily study targets, create flashcard decks for each chapter, and schedule initial retention reviews."

Frequently Asked Questions (FAQ)

How does Anneal protect user privacy during AI interactions?

Anneal implements zero-trust authorization. All requests are authenticated via OAuth 2.1 with PKCE. Tools only operate within the authenticated user's ActorContext. No database credentials or cross-tenant records are ever accessible.

Does Anneal delete historical logs when habits or tasks are removed?

No. Anneal uses an immutable append-only event ledger. Deletions create tombstone markers, and updates record forward pointers (supersedesId). Historical records remain intact for longitudinal data visualization.

What spaced repetition model does Anneal use?

Anneal uses FSRS-5 (Free Spaced Repetition Scheduler), an advanced 9-parameter memory algorithm that models memory stability and retrievability based on cognitive decay curves, outperforming legacy SM-2 models by over 18%.
