Script your Node-RED deployments

The `set_flows` and `get_flows` tools enable headless configuration management for your automation pipelines. You can pipe a local JSON file containing your updated nodes directly into Claude Code, and it will push the entire state to the server in one command. This replaces manual browser imports with repeatable terminal operations. If you need to back up the current state before a migration, your CLI agent grabs the active workspace and writes it to your local filesystem automatically.

Claude Code MCP Server integration

The `update_flow` tool allows targeted modifications to specific Node-RED tabs during automated build steps. Instead of overwriting the entire environment, your script can inject a single new route or modify a webhook handler while leaving the rest of the system untouched. Adding new components is just as fast. Running a command to add a feature prompts the agent to use `install_node`, pulling the required package into the runtime environment before deploying the flow that depends on it.

Monitor instances from the command line

The `get_diagnostics` tool pulls CPU, memory, and JavaScript runtime stats straight to your standard output. You can set up a cron job where Claude Code checks the health of your instance every hour and alerts you if memory usage crosses a threshold. Auditing the environment takes seconds. Your agent runs `get_settings` and `get_nodes` to dump the current configuration and installed packages, letting you verify that your production instance matches your staging environment without ever touching a GUI.
