Connect MyMemory to Cursor

Updated

Definition and quick answer

MyMemory for Cursor is a Model Context Protocol (MCP) connection that lets Cursor's AI agent search, save and read your MyMemory library while you code.

How to connect: Click Add to Cursor from Add memory → MCP in the app for a one-click install, run npx @everstash/mcp setup, or copy the MyMemory MCP config and add it to ~/.cursor/mcp.json with your sm_ API key, then reload MCP servers in Cursor. The agent gets five tools: save_memory, search_memories, list_spaces, get_memory_by_id and delete_memory.

Connection type
Model Context Protocol (MCP), stdio transport
Supported clients
Cursor
Authentication
MyMemory API key (sm_…)
Requirements
Node.js 18+, a MyMemory API key
Package
@everstash/mcp on npm (runs with npx)
Tools exposed
5

Setup steps

  1. 1. Add to Cursor with one click

    Open Add memory → MCP in the app and click Add to Cursor. Cursor opens with the server pre-filled; paste in your API key when Cursor asks for it.

  2. 2. Or run the setup wizard

    npx @everstash/mcp setup finds the MCP clients installed on your computer, asks which to connect and for your API key, then writes each one's config itself, backups included.

    npx @everstash/mcp setup

  3. 3. Create an API key

    Generate a key on the MyMemory dashboard (the API key card on the Overview tab). Keys start with sm_ and grant access to your account, so keep the config file private.

  4. 4. Open the MCP tab in MyMemory

    Sign in at mymemory.dev, click Add memory, and open the MCP tab. Pick your client to see its exact configuration block with a copy button, or use the one-click install button where available.

  5. 5. Or add the server manually

    Paste the block from the MCP tab into ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project) with your API key, then reload MCP servers in Cursor settings.

What Cursor can do with MyMemory

MCP tools available to Cursor
ToolWhat it does
save_memorySaves text, a note or a URL to your library.
search_memoriesRuns hybrid semantic and full-text search; returns up to 100 results.
list_spacesLists the spaces your account can access.
get_memory_by_idReturns the full content of one memory.
delete_memoryPreviews a memory, then deletes it only when called with confirm: true.

Limitations

  • The local server (npx @everstash/mcp) runs on your computer over stdio, so each machine needs Node.js 18+ and its own config. For clients that add a remote MCP server by URL instead, point them at https://api.mymemory.dev/v1/mcp and sign in with your MyMemory account (or send your API key as a Bearer token where the client supports headers) — nothing to install.
