npm install -g @brainfile/cli && brainfile initFirst-class support for agent-to-agent contracts. Assign work to other AI assistants with clear deliverables.
Built-in MCP server lets Claude Code, Cursor, and Cline manage your tasks directly. Zero friction.
A single brainfile.md file. Version control friendly. Branch it, merge it, diff it.
Terminal TUI, full CLI, VSCode kanban sidebar. Use what fits your workflow.
Tasks live in Linear, Jira, or Notion. Code lives in git. Your AI assistant can see your code but has no idea what you're working on. You're constantly context-switching, copy-pasting task descriptions, and manually updating status.
Brainfile puts your task board in a brainfile.md file right in your repo. It's structured YAML that tools can parse, but it's also just markdown you can read and edit. AI assistants update it directly via MCP — no manual syncing.
Add this to your project's .mcp.json and you're done
