Nothing serious here today

Today is the operative word: we check Memoir every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Claude Code Claude Desktop Codex Cursor VS Code

run in your terminal

claude mcp add memoir -- npx -y memoir-mcp

~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "memoir": {
      "args": [

  "mcpServers": {
    "memoir": {
      "args": [

  }
}

This one needs environment variables set before it will start: MEMOIR_MAX_CONTENT (Max characters for content fields), MEMOIR_MAX_OUTCOME (Max characters for outcome/resolution fields), MEMOIR_MAX_ENTRIES (Max entries per session), MEMOIR_MAX_SESSIONS (Max sessions per project (rolling)). The author declared them in the registry entry; get the values from the project itself.

Memoir — questions

Answers built from our own checks of this server.

Why is there no uptime for Memoir?

Memoir runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package memoir-mcp was installed 30 times last week.

How do I connect Memoir?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls memoir-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Memoir?

The npm package memoir-mcp was installed 30 times in the last week. Week over week that is +21%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Memoir open source?

Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
