What is rember-mcp

rember-mcp is a server tool developed by Rember that enables the AI assistant Claude to create flashcards for you using the Model Context Protocol (MCP). This tool leverages spaced repetition, a proven technique to help you study and retain information more effectively. By integrating with Rember, rember-mcp allows you to generate flashcards directly from your conversations or documents, making it easier to remember important information over time.

How to Use rember-mcp

To start using rember-mcp, you'll need to set it up with your Rember API key. This key is essential for the server to access Rember's services and create flashcards. Once you have your API key ready, you can run the server using a simple command in your terminal:

npx -y @getrember/mcp --api-key=YOUR_REMBER_API_KEY

Replace YOUR_REMBER_API_KEY with your actual key. For integration with Claude Desktop, update your configuration file to point to the rember-mcp server. This setup allows Claude to interact with the server to generate flashcards from the data you provide.

When interacting with Claude, you can request flashcards by simply asking, "Help me remember this," or "Create flashcards from this conversation." You can also specify documents, such as PDFs, from which you want Claude to generate flashcards.

Key Features of rember-mcp

Flashcards from Chats: Seamlessly create flashcards from your conversations with Claude. Whenever you encounter useful information in a chat, you can ask Claude to generate flashcards to help you remember it.
Flashcards from Documents: Extract key points from documents such as PDFs and transform them into flashcards. Specify sections or chapters to focus on, making study sessions more targeted and efficient.
Spaced Repetition Scheduling: The flashcards generated are integrated with Rember's spaced repetition system, which schedules reviews at optimal intervals to enhance memory retention.
Simple Setup and Configuration: Running the server requires only a few steps, and integration with Claude Desktop is straightforward. Once set up, you can effortlessly generate flashcards from various data sources.
AI-Assisted Learning: By leveraging Claude's capabilities, rember-mcp offers a smart, intuitive way to manage your learning materials, ensuring you can focus on understanding rather than organizing information.
Customizable Interactions: Tailor your requests to suit your learning needs. Whether you're studying for exams or trying to master new concepts, rember-mcp provides flexible options to create the most relevant flashcards.

rember-mcp is an innovative tool designed to bring AI-assisted learning to your fingertips, enhancing your study habits and helping you remember what matters most.

Allow Claude to create flashcards for you with the official Model Context Protocol (MCP) for Rember. Rember helps you study and remember anything you care about by scheduling spaced repetition reviews. Features and examples:

Create flashcards from your chats "... I like your answer, help me remember it"
Create flashcards from your PDFs "Create flashcards from chapter 2 of this PDF" Rember MCP Demo

Setup

To run the Rember MCP server using npx, use the following command:

npx -y @getrember/mcp --api-key=YOUR_REMBER_API_KEY

Make sure to replace YOUR_REMBER_API_KEY with your actual Rember api key, which you can find in your Settings page. The API key should follow the format rember_ followed by 32 random characters.

Usage with Claude Desktop

Add the following to your claude_desktop_config.json. See here for more details.

 "mcpServers": {
 "rember": {
 "command": "npx",
 "args": ["-y", "@getrember/mcp", "--api-key=YOUR_REMBER_API_KEY"]

Available tools

create_flashcards: Create flashcards with AI. This tool takes a list of notes from Claude, it calls the Rember API to generate a few flashcards for each note. After learning something new in your chat with Claude, you can ask "help me remember this" or "create a few flashcards" or "add to Rember".

Best practices for MCP servers

Here's a collection of lessons we learned while developing the Rember MCP server:

Set up logging to stderr as early as possible, it's essential for debugging.
Create a simple MCP tool first and verify Claude can call it properly.
Invest time in iterating on the tool description:
Include details about your product and its URL. This serves two purposes: it helps Claude use the tool properly and allows Claude to answer user questions about the product.
Clearly explain what MCP is, in a few instances Claude hallucinated that MCP stands for "Multiple Choice Prompts", yikes
Describe the tool inputs thoroughly
Explain what happens after Claude calls the tool, we clarify that the input notes array is sent to the Rember API, which generates flashcards for each note
Provide examples of how the tool can be used (e.g., "create flashcards from a conversation with Claude," "create flashcards from PDFs"), and give Claude specific instructions for each use case
List examples of how users might invoke the tool (e.g., "help me remember this," "add to Rember," "create a few flashcards")
Include a list of rules to guide Claude in using the tool appropriately
Use the tool call response strategically, it's not shown directly to users but interpreted by Claude:
On success, the Rember API does not return the number of created flashcards, all Claude knows is the number of created rembs. We specify this to Claude because otherwise it tends to hallucinate the number of created flashcards.
For users who've reached their monthly limit, we instruct Claude to inform them about the Rember Pro subscription option with the relevant URL
Implement retries for transient errors with suitable timeouts
We collected enough edge cases that testing manually on Claude Desktop (our main target MCP client) became cumbersome. We created a suite of unit tests by simulating Claude Desktop behavior by calling the Claude API with the system prompt from claude.ai. In the current iteration, each test simulates a chat with Claude Desktop for manual inspection and includes a few simple assertions. What's missing:
Telemetry and observability, currently we are blind if something goes wrong
More exhaustive error handling
More iterations on the tool description
More automated tests
