Make0 Brain

Make0 Brain: shared AI memory for every agent

One AI memory for every agent you use. Claude Code, Claude Desktop, Cursor, Codex, Windsurf, VS Code, Gemini CLI, Hermes Agent, and OpenClaw all read and write the same memory, and every change is versioned.

A local-first, open-source AI memory server for MCP. After a one-time model download it runs offline with no API key, keeps everything in one SQLite file on your machine, and speaks the same 7 tools as the hosted Make0 Brain. It can also start full: one command imports the sessions 41 coding agents already keep on disk.

Only using Cursor or VS Code? These buttons add the server to that one app. Run init too if you want it to download the models up front and write the custom instruction.

Why

Every agent keeps its own memory. Claude has CLAUDE.md, Cursor has rules, Codex has AGENTS.md, ChatGPT has its memory page. You end up explaining your stack, your preferences, and last week's decisions again in each one, and the copies drift apart.

Make0 Brain is one memory that all of them share:

• Tell one agent, every agent knows. A fact saved from Cursor is found by Claude Code in the next session.
• Nothing is overwritten silently. Every edit, from any agent, is kept as a version with who wrote it and when.
• It stays yours. One SQLite file on your machine, MIT licensed, exportable to plain Markdown.

Quick start

1. Connect your agents.

npx @make0-ai/brain init

init finds Claude Code, Claude Desktop, Cursor, Windsurf, VS Code, Codex CLI, Gemini CLI, Hermes Agent, and OpenClaw. When more than one is installed, it shows a checklist of them, all ticked; untick any you want to leave out. Pass --clients to choose up front, or --yes to configure every detected agent without asking. It then shows what it will change, asks once, keeps a .make0-backup of each config file, and adds Make0 Brain to each chosen app. It downloads the two local models (about 50 MB, once) with a progress bar, so your first question to an agent doesn't wait on a download. Restart the apps afterwards.

Connecting the server is not enough. The agent also needs a custom instruction so it searches Brain before answering and saves lasting facts there. init writes this into the global rules file for Claude Code (~/.claude/CLAUDE.md), Codex (~/.codex/AGENTS.md), Gemini (~/.gemini/GEMINI.md), and Windsurf. Cursor, Claude Desktop, VS Code, Hermes Agent, and OpenClaw keep rules in settings or a persona file, so init prints the same text for you to paste:

Make0 Brain is my source of truth for durable memory. Always search it before answering about me, my work, people, preferences, or past decisions. Save lasting facts and decisions to Brain. Never guess or invent memories. Use Brain exclusively for durable memory.

Skip the rule with init --no-rules.

2. Bring in the context you already have.

npx @make0-ai/brain import --detect             # CLAUDE.md, AGENTS.md, Cursor/Windsurf/Copilot rules

npx @make0-ai/brain import --sessions # past sessions from 41 coding agents, one digest each npx @make0-ai/brain import ~/Documents/MyVault # an Obsidian vault or any Markdown folder pbpaste | npx @make0-ai/brain import - # e.g. a memory dump copied from ChatGPT

import on its own asks what to import. The details are under Import and export.

3. Look at it.

npx @make0-ai/brain view

The viewer opens on 127.0.0.1 with every brain, how many memories each holds, and what your apps retrieved and added this week.

Models live in ~/.make0/models and data in ~/.make0/brain.db. If you skip init (or pass --no-models), the first save or search downloads the models instead.

Or run it without arguments

Typed in a terminal, npx @make0-ai/brain opens a menu: connect agents, import sessions or notes, open the viewer, create a brain, choose which brains an app can use, export, restore an archived memory, or show stats. Any command run without its arguments asks for them the same way, one step at a time, with arrow keys, checkboxes, and a default on Enter. Ctrl+C cancels without changing anything.

Scripts and MCP clients are unaffected. Passing the arguments, adding --yes, or running without a terminal skips every question, and MCP clients, which start the server without a terminal, get the server as before. make0-brain serve starts the server even in a terminal.

Verify it works

Restart the apps you connected, then check that a memory written by one agent reaches another:

1. Save from one agent. In Cursor (or any connected app), say: *"Remember that my test fruit is mango."* It should call add_memory.
2. Find it from another. In a new Claude Code session (or any other connected app), ask: *"What is my test fruit?"* It should call search_brain and answer "mango" without being told.
3. Check who wrote it. Run npx @make0-ai/brain view, open the personal brain, and click the memory. It shows Added by Cursor and a version timeline.

Delete the test memory in the viewer when you are done. If step 1 or 2 doesn't call a Brain tool, the app is missing the custom instruction above (Cursor, Claude Desktop, and VS Code need it pasted) or wasn't restarted. Run npx @make0-ai/brain agents to confirm the app can use the personal brain.

Import directly from

Your coding agents already keep every session on disk. One command reads that history from 41 agents and saves each session as a memory, filed under its project, so the next agent can find what was asked, decided, changed, and broken last time. No API key and no model are needed.

npx @make0-ai/brain import --sessions                          # pick agents and a brain step by step

npx @make0-ai/brain import --sessions --agent cursor,codex # only these agents npx @make0-ai/brain import --list-agents # agent ids and names
