List all ThingTemplates available in the ThingWorx model. ThingTemplates are the type definitions Things instantiate from. Used by agents to understand the schema available before creating or inspecting Things.
AI agents call list_thing_templates to retrieve information from Thingworx 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 metadata about available ThingTemplates (type definitions) in the ThingWorx model. It performs pure enumeration/discovery with no capability to create, modify, delete, execute code, or move data. The blast radius of misuse is minimal — an agent could only learn what templates exist, which is informational. Classification: Read.
From the tool's definition Tool description states it 'List all ThingTemplates available' — a retrieval operation with no modification or side effects. The phrase 'understand the schema available' reinforces read-only introspection.
Attacks that exploit this kind of access
List all ThingTemplates available in the ThingWorx model. ThingTemplates are the type definitions Things instantiate from. Used by agents to understand the schema available before creating or inspecting Things. It is categorised as a Read tool in the Thingworx MCP Server, which means it retrieves data without modifying state.
Register the Thingworx MCP server in PolicyLayer and add a rule for list_thing_templates: 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 Thingworx. Nothing to install.
list_thing_templates 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_thing_templates 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_thing_templates. 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.
list_thing_templates is provided by the Thingworx MCP server (nobanks/thingworx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
