# Setup & Installation

### Prerequisites

Both of the following must be in place before AI Agent Security can function:

1. Nightfall endpoint agent v1.2.12.11+ installed and running on the endpoint; The agent auto-installs and keeps `nightfall-hook-relay` updated, and adds it to the system `PATH`. The hooks call the binary by name, so without the agent the hooks resolve to nothing.
2. MDM configuration profile v3+ deployed via your MDM provider (Jamf, Mosyle, Kandji, etc.)
3. MDM scope selected - the device group / Blueprint / Smart Group / assignment that will receive the deployment.
4. Claude Code is reasonably current on managed devices.
5. You have the three pieces from this package: the payload (`payloads/nightfall-hooks.json`) and the scripts for your platform (`scripts/macos/` or `scripts/windows/`).

If the MDM profile has not been deployed, the agent will show a missing permissions error and you will not see any local or remote MCP servers across installed devices.
