+## Limitations
+
+The agent firewall has important limitations that affect its security coverage.
+
+* **Only applies to processes started by the agent**: The firewall only applies to processes started by the agent via its Bash tool. It does not apply to Model Context Protocol (MCP) servers or processes started in configured {% data variables.product.prodname_copilot_short %} setup steps.
+* **Only applies within the {% data variables.product.prodname_actions %} appliance**: The firewall only operates within the {% data variables.product.prodname_actions %} appliance environment. It does not apply to processes running outside of this environment.
+* **Bypass potential**: Sophisticated attacks may bypass the firewall, potentially allowing unauthorized network access and data exfiltration.
+
+These limitations mean that the firewall provides a layer of protection for common scenarios, but should not be considered a comprehensive security solution.
