+## {% data variables.copilot.copilot_coding_agent %} recommended allowlist
+
+The {% data variables.copilot.copilot_coding_agent %} includes a built-in firewall with a recommended allowlist that is enabled by default. The recommended allowlist allows access to:
+
+* Common operating system package repositories (for example, Debian, Ubuntu, Red Hat).
+* Common container registries (for example, Docker Hub, Azure Container Registry, AWS Elastic Container Registry).
+* Packages registries used by popular programming languages (C#, Dart, Go, Haskell, Java, JavaScript, Perl, PHP, Python, Ruby, Rust, Swift).
+* Common certificate authorities (to allow SSL certificates to be validated).
+* Hosts used to download web browsers for the Playwright MCP server.
+
+For more information about configuring the {% data variables.copilot.copilot_coding_agent %} firewall, see [AUTOTITLE](/copilot/how-tos/use-copilot-agents/coding-agent/customize-the-agent-firewall).
