Tools (13)
Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].
nr_create_nodesCreate one or more new nodes/groups in a single deploy. Each node dict must include 'id', 'type', and 'z' (target tab ID). Groups need 'type': 'group'. Config nodes (e.g. ha-entity-config) use 'z': '' for global scope.
nr_delete_nodesDelete one or more nodes by ID. Also cleans up references: removes deleted IDs from group.nodes arrays and from other nodes' wires arrays.
nr_get_debug_outputRead debug output from flow context. Use when a flow has a catch node that stores errors/debug data to flow context. Pass key=null to list all context keys. Trigger flow with nr_inject first, then read this.
nr_get_flowGet a single Node-RED tab with all its nodes and groups. Accepts tab name (case-insensitive) or tab ID.
nr_get_flow_contextRead Node-RED flow context variables. Pass key=null to list all keys, or a specific key to get its value.
nr_get_flow_summaryQuick overview of all Node-RED tabs with node counts and groups.
nr_get_function_codeExtract full JavaScript code from a Node-RED function node.
nr_get_installed_modulesList installed Node-RED modules and their node types. Optionally filter by module name or node type containing `query` string. Returns module name, version, and list of node types provided.
nr_get_node_configGet full node configuration including wires, upstream/downstream connections, and group membership.
nr_injectTrigger an inject node to fire immediately. Use nr_search_nodes to find inject nodes first. The node must be of type 'inject'.
nr_install_moduleInstall a new Node-RED module (npm package) from the registry. Use nr_get_installed_modules to check what's already installed first. Installation may take 30-60 seconds.
nr_safe_deployDeploy changes to a Node-RED node with optimistic locking. Uses correct GET→POST pattern (never PUT). Preserves tab order.
nr_search_nodesSearch Node-RED nodes by name, type, or function code content. Searches in: name, type, func, template, action fields.
