Our reading of MyMemory, from the data

MyMemory is a notes & knowledge MCP server, listed in the official MCP Registry.

We haven't measured its tool list yet, so its token cost is unknown.

Maintenance is active: the last public signal was 2 days ago (2026-10-16). For comparison, 71% of notes & knowledge servers are active or maintained.

It runs either locally over stdio or as a hosted endpoint and needs one secret (EVERSTASH_API_KEY); use a scoped, least-privilege key.

Install MyMemory MCP server

claude mcp add mymemory-dev -e EVERSTASH_API_KEY='<everstash-api-key>' -- npx -y @mymemory.dev/mcp

{
  "mcpServers": {
    "mymemory-dev": {
      "command": "npx",
      "args": [
        "-y",
        "@mymemory.dev/mcp"
      ],
      "env": {
        "EVERSTASH_API_KEY": "<everstash-api-key>"
      }
    }
  }
}

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project).

{
  "mcpServers": {
    "mymemory-dev": {
      "command": "npx",
      "args": [
        "-y",
        "@mymemory.dev/mcp"
      ],
      "env": {
        "EVERSTASH_API_KEY": "<everstash-api-key>"
      }
    }
  }
}

Settings → Developer → Edit Config (claude_desktop_config.json), then restart.

{
  "servers": {
    "mymemory-dev": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@mymemory.dev/mcp"
      ],
      "env": {
        "EVERSTASH_API_KEY": "<everstash-api-key>"
      }
    }
  }
}

Add to .vscode/mcp.json in your workspace.

{
  "mcpServers": {
    "mymemory-dev": {
      "command": "npx",
      "args": [

        "@mymemory.dev/mcp"
      ],
      "env": {
        "EVERSTASH_API_KEY": "<everstash-api-key>"
