Protect Local Coding Agents
Silmaril discovers supported local coding agents, configures their protection, and shows their current state in one place.
The app also provides a local inventory of plugins, skills, MCP servers, and connectors, plus recent protection activity. Direct installs show an Update action when a verified update is ready.
Install The App
You need macOS 14 or later, a supported coding agent, and the API URL and key supplied by Silmaril.
Download Silmaril 0.2.0 from the verified Silmaril download service.
Open the DMG, then drag Silmaril to the Applications folder.
Open Silmaril from Applications and complete the first-run review.

If your Mac is managed by your organization, follow your administrator's installation process instead.
Connect And Protect
Complete every required item. An unavailable capability may show Not needed, and notifications can be enabled later in Settings.
Open Settings, enter the Silmaril API URL and key you received, then select Save. The key is entered once and stored in your login Keychain.

On Protection, keep Shadow selected while you confirm agent coverage. Shadow mode reports protection activity without blocking it.
Select Protect All. Wait for each installed agent to show Protected. If an agent shows Restart required, restart that app or begin a new terminal session, then check again.

Resolve Common Issues
- Silmaril does not open
- Confirm that your Mac runs macOS 14 or later and that Silmaril is in Applications. Download the DMG again if needed. If macOS reports that the app is damaged or cannot be verified, stop and contact Silmaril Support instead of bypassing the warning.
- No agents found
- Install or start a supported coding agent, return to Silmaril, and refresh the agent list.
- Connection rejected
- Re-enter the API URL and key supplied by Silmaril in Settings, then select Save. Contact Support if the credentials are still rejected.
- Needs attention or Restart required
- Open the affected agent and follow the action shown. After a repair or update, restart the named app or begin a new terminal session.
- Notifications are off
- Open Settings and select Enable next to Notifications. If permission was previously denied, enable Silmaril in macOS System Settings.
- The issue continues
- In Settings, select Export Diagnostics. Then open Support in Silmaril to send the export, or email aum@silmaril.dev.
