Cursor MCP in 50 Seconds

This guide follows the same flow as the video walkthrough on the Python MCP page: sign in, configure MCP, add the system prompt, and test save_memory.

Step-by-step

Section titled “Step-by-step”

  1. Sign in and get an API key

    Open yomemo.ai and sign in with GitHub, email, or Google. Click Settings in the left menu, then API Key. If you’re new, click Rotate Key to generate a new key. Keep your key and (if you use a key pair) your private PEM path for the next step.

  2. Configure MCP in Cursor

    Edit ~/.cursor/mcp.json (Windows: %APPDATA%\Cursor\User\mcp.json) and add the YoMemo MCP server with your MEMO_API_KEY and MEMO_PRIVATE_KEY_PATH. Restart Cursor and ensure MCP is enabled.

  3. Copy the system prompt

    Go to github.com/yomemoai/yomemo-prompts, open system-v0.0.0.txt (or the latest protocol file), and copy the full contents.

  4. Add the prompt as a Cursor rule

    In Cursor, add that text as a system rule (e.g. in Rules for AI or your project/global rules). This makes the AI call save_memory at the right moments (fact updates, decisions, high-value discoveries).

  5. Test save

    In any Cursor chat, ask the AI to remember something (e.g. a preference or fact). Then open a new chat and ask it to recall—or use load_memories—to confirm the memory is stored and decrypted correctly.
