AI agents call show to retrieve information from Things MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool navigates to and displays existing data structures (areas, projects, tags, todos, lists) in the Things 3 app. No creation, modification, deletion, or execution of commands occurs—it purely retrieves and presents information to the user. This is a standard Read category operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'show' and description indicating navigation to and display of areas, projects, tags, todos, or built-in lists. The verb 'display' and 'navigate to' are read-only operations that retrieve and present existing data without modification.

Register the Things MCP Server MCP server in PolicyLayer and add a rule for show: 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 MCP Server. Nothing to install.
show 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 show 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 show. 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.
show is provided by the Things MCP Server MCP server (mieluoxxx/things_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
