• resolve_dependencies Given one or more companion spec namespace aliases, returns the full resolved dependency list that MUST go in the YAML `namespaces:` section. Always call this b
• list_namespaces List all well-known OPC UA companion spec namespace aliases with their full names, URIs, and dependencies. Use this to discover what namespaces are available.
• list_types List ALL ObjectTypes, VariableTypes, and InterfaceTypes defined in a specific companion spec namespace. ALWAYS call this before using any type from a namespace
• get_type_details Get detailed information about a specific type: its components, properties, methods, interfaces, and optional members. Use this to understand a type's structure
• search_types Search for types across ALL companion specs by keyword. Use this when you don't know which namespace defines a type. Returns matching types with their namespace
• find_reusable_block Find reusable Interfaces / AddIns by capability — pass a member name or keyword (e.g. "SerialNumber", "DeviceHealth", "Location") and get the standard blocks th
• find_engineering_unit Find the official UNECE Rec. 20 engineering unit symbol for a given description. ALWAYS call this before using any engineering unit — NEVER guess unit symbols.
• get_dsl_reference Get the grammar reference for the OPC UA modeler YAML DSL: file header, top-level sections, name-prefix conventions, minimal examples, and common mistakes. Call
• opcua_model_validate Validate an OPC UA YAML model for correctness. Returns diagnostics with severity (error/warning/info), codes, messages, and line numbers. Works without an API k
• opcua_model_generate Generate OPC UA NodeSet2.xml and the symbols CSV from a YAML model. Requires an API key (set OPCUA_MODELER_API_KEY env var). NodeIds stay stable only if each re
• opcua_model_reverse Reverse-engineer a NodeSet2.xml file back into the YAML DSL format. Requires an API key (set OPCUA_MODELER_API_KEY env var). Optionally specify the target names
• opcua_model_create Generate an OPC UA YAML model from a natural language description using AI. Requires an API key (set OPCUA_MODELER_API_KEY env var). The AI will auto-detect rel
