How to Set Up and Use Dex
Dex is a personal operating system starter kit that positions your AI assistant as a Chief of Staff, maintaining structured knowledge about your projects, contacts, meetings, and tasks in a local Markdown vault. It ships with role-based slash commands (/daily-plan, /meeting-prep, /career-coach), integrations for Google Calendar and Granola meeting transcripts, and a task sync MCP server that keeps unique IDs consistent across your vault — no cloud subscription required for core functionality.
Prerequisites
- Cursor (free tier or Pro) as your primary MCP client, or Claude Code (Claude Pro/Max subscription)
- Git for cloning and updating the repository
- Node.js 18+ for automation features
- Python 3.10+ for the MCP servers and task sync functionality
- macOS Command Line Tools (installed automatically on first run on macOS)
Clone the Dex repository
Clone Dex to your Documents folder. The installer expects this default location.
git clone https://github.com/davekilleen/dex.git ~/Documents/dex
cd ~/Documents/dexRun the installer
The install script sets up the Python virtual environment, installs MCP server dependencies, and configures the vault structure.
chmod +x install.sh && ./install.shOpen Dex in Cursor or Claude Code
Open the dex directory in Cursor as a project, or start Claude Code from the directory. The MCP servers are registered automatically via the project configuration.
# Claude Code
cd ~/Documents/dex && claude
# Or open in Cursor
cursor ~/Documents/dexRun the onboarding slash command
Inside your AI client, run /setup to complete role-based onboarding. Dex will ask about your role and adapt its templates and commands accordingly.
/setupConfigure optional integrations
Enable Google Calendar integration for meeting prep, or connect Granola for automatic meeting transcript processing. Run /ai-setup to configure which AI models to use.
/ai-setupDex Examples
Client configuration
The Dex MCP servers are configured automatically by the installer in the project directory. The Work MCP server for task sync runs via the Python venv.

- "/career-coach" — get structured career development guidance
- "Sarah seemed worried about the timeline but interested in a Q2 pilot" — auto-routes to person and project pages
- "/dex-level-up" — discover features you have not used yet
- "/dex-update" — safely pull the latest Dex updates"Troubleshooting Dex
Install script fails with Python not found or wrong version
Ensure Python 3.10+ is installed and available as `python3`. On macOS, install it via `brew install [email protected]`. On Windows, download from python.org and add it to PATH.
MCP servers not loading in Cursor or Claude Code
The installer writes MCP config to the project's .cursor/mcp.json or equivalent. Reopen the dex folder as the root project in your editor. If the Python venv path is wrong, re-run ./install.sh to regenerate it.
Google Calendar integration not working in /meeting-prep
Google Calendar MCP is macOS-only and requires running /ai-setup to configure credentials. Ensure you have granted calendar access when prompted during setup.
