Cerveau.dev
Multi-brain system for Claude Code. One protocol, many projects, zero duplication. MDPlanner keeps every session on track.
Why Cerveau.dev?
Multi-Brain
One protocol, many projects. Each brain gets selective rules, hooks, and agents — no duplication, no drift.
Selective Loading
Only load what each brain needs. Declare stacks, practices, and workflows per project. Every saved token is faster context.
MDPlanner Integration
Single source of truth for tasks, notes, decisions, and progress. Claude reads and writes it every session.
Hooks Enforcement
Boot reminders, commit validation, checkpoint checks, and progress gates. The protocol runs whether Claude remembers or not.
Protocol-Driven Workflow
Claude picks up exactly where it left off. Every session starts with full context — tasks, decisions, and progress loaded from MDPlanner.
Zero Footprint
No files added to your project repos. The brain lives outside your code. Your codebase stays clean.
Bring Your Own Rules
No rules ship by default. Generate stack, practice, and workflow rules with a single Claude prompt.
Open Source
AGPL-3.0. Self-host everything. MDPlanner runs in a container. No external dependencies required.
Quick Start
Install
One command installs the protocol, starts MDPlanner, and registers MCP globally.
curl -fsSL https://cerveau.dev/install.sh | bashCreate a Brain
Spawn a brain for your project. Zero files added to your codebase. For an existing project, clone the repo first, then point spawn at it.
cerveau spawn MyApp /tmp/MyAppLaunch
Open the brain session from anywhere. Claude boots with full context automatically.
cerveau boot MyAppBoot
Type 'boot' inside the session. Claude reads the rules, fills local-dev.md, and configures MDPlanner state.
