README
brain
brain gives Claude Code, Cursor, Codex, OpenClaw, Hermes, and MCP-capable
tools one shared local memory. Notes are stored as git commits in ~/.brain,
indexed for search, and available through the CLI, TUI, and MCP server.
Install
Homebrew on macOS installs the prebuilt binary:
brew install codejunkie99/tap/brain
brain onboard
From source:
git clone https://github.com/codejunkie99/brain.git
cd brain
cargo install --path crates/brain-cli
brain onboard
First run
brain onboard
Onboarding creates or keeps ~/.brain, lets you choose which agents to wire,
shows the exact files it will write, then asks before saving. It does not
create cloud accounts, install daemons, store API keys, or send memory anywhere.
You can type agent names naturally:
claude code
wire claude code and cursor
codex openclaw hermes
all
none
Scripted setup:
brain onboard --agents all --yes
brain onboard --agents claude-code,cursor,codex --yes
brain onboard --agents openclaw,hermes --yes
Refresh managed wiring later:
brain onboard --agents all --yes --reconfigure
Use it
brain note "remember that auth uses PKCE"
brain ask "auth"
brain log
brain tui
brain tui opens the terminal dashboard.
Agent files
When selected during onboarding, brain can write:
| Agent | Files |
|---|---|
| Claude Code | ~/.claude/mcp_servers.json, ~/.claude/CLAUDE.md |
| Cursor | <project>/.cursor/mcp.json, <project>/.cursor/rules/brain.mdc |
| Codex | ~/.codex/config.toml, ~/.codex/AGENTS.md |
| OpenClaw | ~/.openclaw/workspace/BRAIN.md |
| Hermes | <project>/AGENTS.md |
Existing files are not overwritten by default. Managed prompt blocks use
BRAIN:START / BRAIN:END markers so re-runs do not duplicate content.
Sync
Sync is explicit:
brain remote add origin <url>
brain push
brain pull
Troubleshooting
brain doctor
brain doctor --deep
Use doctor --deep when search or log output looks inconsistent. It rebuilds
the local SQLite index from git without changing the source-of-truth event log.
By default, memory lives in ~/.brain. Override it with BRAIN_DIR or
--brain-dir <path>.
Commands
brain onboard
brain note "any text"
brain ask "word"
brain log
brain tui
brain doctor
brain serve --mcp
brain remote add origin <url>
