List all available web applications.
AI agents call app_list to retrieve information from Goose App Maker MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about existing web applications without creating, modifying, deleting, or executing any operations. It is a straightforward read operation with minimal risk if misused by an AI agent—the worst outcome would be disclosure of application names or metadata already stored in the system.
From the tool's definition Tool name 'app_list' and description 'List all available web applications' indicate data retrieval with no modification or side effects.

Yes. Add a rate_limit block to the app_list rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for app_list. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
