Tools

Functions exposed to the LLM to take actions

NameDescription
list_thingsA

List all Things registered in the ThingWorx model. Returns Thing names, descriptions, and parent ThingTemplate. The standard read path for an agent that needs to discover the industrial asset inventory.

get_thingA

Get metadata for a specific Thing by name. Returns the Thing's properties, services, events, and implemented ThingShapes. Used to discover the surface area of a Thing before reading or writing it.

read_propertyA

Read the current value of a single Property on a Thing. Returns the property value plus its data type. The standard read path for an agent that needs the live state of an industrial asset.

write_propertyA

Write a new value to a Property on a Thing. Gated by THINGWORX_ALLOW_WRITE=true because property writes can change the state of real industrial equipment (setpoints, modes, configuration). The MCP refuses to write unless the operator has explicitly authorized it.

invoke_serviceA

Invoke a named Service on a Thing. Gated by THINGWORX_ALLOW_INVOKE=true (separate from write) because services execute named actions that can include PLC commands, scripted workflows, and downstream system calls. The MCP refuses to invoke unless the operator has explicitly authorized it.

list_thing_templatesA

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.

get_thing_templateA

Get the full definition of a ThingTemplate by name, including property + service + event signatures, parent template, and implemented ThingShapes.

search_thingsA

Search the ThingWorx model by free-text expression matched against Thing names + descriptions. Returns up to max_items results. Used when the agent does not know the exact Thing name (e.g. 'find all conveyor things in Line 4').
