Overview

Description from the maker (original English)

Zero-friction personal operating system: habits, tasks, and FSRS-5 study retention via remote MCP.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Works in Claude on the web, desktop and mobile:

  1. Open Settings → Connectors
  2. Press Add custom connector
  3. Paste the address below and press Add
  4. If it asks you to sign in, sign in with the maker

https://anneal-os.vercel.app/api/mcp

Run this in your terminal

claude mcp add --transport http anneal https://anneal-os.vercel.app/api/mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

  "mcpServers": {
    "anneal": {
      "url": "https://anneal-os.vercel.app/api/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "anneal": {
      "type": "http",
      "url": "https://anneal-os.vercel.app/api/mcp"
    }
  }

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)

Common questions

Is Anneal safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.6) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Anneal MCP Server

Official Model Context Protocol Remote Server for the Anneal Personal Operating System

Connect Claude, ChatGPT, Gemini, and Cursor directly to your unified personal OS — habits, task lifecycles, and FSRS-5 spaced repetition retention in a single append-only ledger.

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%.
