Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "memoir": {
      "command": "npx",
      "args": [
        "-y",
        "memoir-mcp"
      ],
      "env": {
        "MEMOIR_MAX_CONTENT": "your-value",
        "MEMOIR_MAX_OUTCOME": "your-value",
        "MEMOIR_MAX_ENTRIES": "your-value",
        "MEMOIR_MAX_SESSIONS": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add memoir --env MEMOIR_MAX_CONTENT=your-value --env MEMOIR_MAX_OUTCOME=your-value --env MEMOIR_MAX_ENTRIES=your-value --env MEMOIR_MAX_SESSIONS=your-value -- npx -y memoir-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "memoir": {
      "command": "npx",
      "args": [
        "-y",
        "memoir-mcp"
      ],
      "env": {
        "MEMOIR_MAX_CONTENT": "your-value",
        "MEMOIR_MAX_OUTCOME": "your-value",
        "MEMOIR_MAX_ENTRIES": "your-value",
        "MEMOIR_MAX_SESSIONS": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "memoir": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "memoir-mcp"
      ],
      "env": {
        "MEMOIR_MAX_CONTENT": "your-value",
        "MEMOIR_MAX_OUTCOME": "your-value",
        "MEMOIR_MAX_ENTRIES": "your-value",
        "MEMOIR_MAX_SESSIONS": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Memoir safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.3) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

memoir-mcp

Structured session journals for AI agents. Persistent memory across sessions -- no more repeating dead ends.

When a session ends, all reasoning is lost -- what was tried, what failed, what's blocked. The next session starts from scratch and repeats the same mistakes. memoir logs it all and hands it off so the next session picks up where the last one left off.

Works with any MCP client: Claude Code, Cursor, Codex, Windsurf, and more.

Install

Claude Code

claude mcp add memoir -s user -- npx -y memoir-mcp

Other MCP clients

npx -y memoir-mcp

How it works

Automatic project detection -- identifies the project by its git root, so logs stay scoped without any configuration.
Implicit sessions -- a session is created automatically on first log. No setup step.
Rolling retention -- keeps the last 20 sessions per project (configurable). Old sessions are pruned automatically.

Tools

Write

Tool	Description
`log_attempt`	Record something that was tried and its outcome.
`log_blocker`	Flag something that's stuck and why.
`resolve_blocker`	Mark a blocker as resolved with what fixed it.
`log_decision`	Record a design or architecture choice and its rationale.
`end_session`	Close the current session with an optional summary.

Read

Tool	Description
`get_handoff`	Structured summary of the last session -- what was attempted, what's blocked, what was decided.
`get_history`	Query past sessions (default: last 3, max 20).
`get_blockers`	List unresolved (or resolved) blockers across all sessions.

Storage

Single SQLite file at ~/.memoir/memoir.db. No API keys, no external services.

Configuration

All limits are configurable via environment variables:

Variable	Default	Description
`MEMOIR_MAX_CONTENT`	500	Max characters for content fields
`MEMOIR_MAX_OUTCOME`	300	Max characters for outcome/resolution fields
`MEMOIR_MAX_ENTRIES`	50	Max entries per session
`MEMOIR_MAX_SESSIONS`	20	Max sessions per project (rolling)

Example with custom limits:

claude mcp add memoir -s user -e MEMOIR_MAX_CONTENT=1000 -e MEMOIR_MAX_ENTRIES=100 -- npx -y memoir-mcp

Handoff output uses a compact format to keep context window usage low.
