Perplexity

Direct Node-RED flow orchestration

Stop jumping between your browser and terminal. You can use `add_flow` to push new logic or `update_flow` to tweak existing tabs directly through your agent. It handles the JSON payload for you. If you need to wipe a configuration clean, `set_flows` makes that state change instant.

Real-time Node-RED system monitoring

Keep an eye on your runtime health without manual checks. The `get_diagnostics` tool pulls current memory usage and system status straight into your chat. If a service feels sluggish, use `get_nodes` to audit your palette. You’ll see exactly what’s installed and identify if you need to run `install_node` for a missing dependency.

Full Node-RED runtime control in Claude Desktop

Every configuration setting is accessible through your chat interface. Use `get_settings` to verify your environment variables before you make any changes to your production logic. Need to clean up your workspace? Use `remove_node` to prune unused modules. It keeps your Node-RED environment lean and prevents dependency bloat.
