Quick overview of all Node-RED tabs with node counts and groups.

Get a single Node-RED tab with all its nodes and groups. Accepts tab name (case-insensitive) or tab ID.

Search Node-RED nodes by name, type, or function code content. Searches in: name, type, func, template, action fields.

Extract full JavaScript code from a Node-RED function node.

Get full node configuration including wires, upstream/downstream connections, and group membership.

Read Node-RED flow context variables. Pass key=null to list all keys, or a specific key to get its value.

Deploy changes to a Node-RED node with optimistic locking. Uses correct GET→POST pattern (never PUT). Preserves tab order.

List 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.

Trigger an inject node to fire immediately. Use nr_search_nodes to find inject nodes first. The node must be of type 'inject'.

Create 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.

Delete one or more nodes by ID. Also cleans up references: removes deleted IDs from group.nodes arrays and from other nodes' wires arrays.

Install 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.

Read 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.
