Rember

- Create flashcards from chat conversations— Ask Claude to turn key takeaways from your conversation into flashcards usingcreate_flashcards.
- Generate flashcards from PDFs and documents— Request flashcards from specific sections of uploaded files, such as a chapter or article.
- Save study material directly to Rember— Use phrases like “help me remember this” to send notes to Rember for spaced repetition review.

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

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

Make sure to replaceYOUR_REMBER_API_KEYwith your actual Rember api key, which you can find in yourSettings page. The API key should follow the formatrember_followed by 32 random characters.

Add the following to yourclaude_desktop_config.json. Seeherefor more details.

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

- 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".

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

-

Set up logging tostderras 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

- Telemetry and observability, currently we are blind if something goes wrong
- More exhaustive error handling
- More iterations on the tool description
- More automated tests
