List trashed tasks. Ordered by modification date, newest first.
AI agents call list_trash to retrieve information from Things Cloud MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and lists information about trashed tasks ordered by modification date. It performs no data creation, modification, deletion, or execution. The action is passive observation of existing trash state, making it a Read category risk with low severity since it accesses non-current data that has already been removed from active task lists.
From the tool's definition Tool name 'list_trash' and description 'List trashed tasks' indicate a read-only query operation that retrieves already-deleted task data with no side effects.

Register the Things Cloud MCP server in PolicyLayer and add a rule for list_trash: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Things Cloud MCP. Nothing to install.
list_trash is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_trash 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 list_trash. 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.
