## Codex and Claude Code

[Contact Silmaril](https://cal.com/silmaril/30min) for plugin access and installation instructions. For managed protection on Macs, use the [macOS app](/docs/macos).

## Expected result

After installation, start a new agent session and confirm its activity appears in Silmaril. Coverage depends on the lifecycle hooks exposed by the agent. Follow its plugin setup guide to verify the supported boundaries.

## Next steps

To protect a service you run, start with the [quick start](/docs/start/quickstart). To manage protection for coding agents across Macs, use [Silmaril for macOS](/docs/macos). To review findings from an MCP client, connect [Firewall MCP](/docs/integrations/firewall-mcp).
