Best Node-RED MCP Servers
Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways.
Why this server?
Generates starter Node-RED exports via the architect agent, providing namespace designs with source bindings wired at deploy time.
AlicenseAqualityAmaintenanceIndustry 4.0 / IIoT AI agents for manufacturing: explain OEE losses per shift, triage machine alarms, find downtime root causes, prepare predictive-maintenance jobs and write shift reports from Unified Namespace (UNS), MQTT or historian data. Plus an industrial AI-readiness diagnostic and a vendor-neutral digital-transformation advisor. Works in Claude Code, Codex and any MCP client.17279 npmMITWhy this server?
Debug Node-RED flows on Venus OS, including MQTT topic tracing and flow debugging.
AlicenseAqualityAmaintenanceConnect AI assistants to Victron Energy systems to read real-time solar, battery, grid, and inverter data from your local network via Modbus TCP or MQTT.3295 npm4MITWhy this server?
Provides tools for managing Node-RED flows and nodes, including creating, reading, updating, deleting flows, adding/removing/rewiring nodes, capturing debug output, and analyzing graph topology.
AlicenseBqualityDmaintenanceConnects AI assistants to the Node-RED Admin API, enabling flow inspection, node management, graph analysis, debug capture, and rollback operations through natural language.3714 npmMITWhy this server?
Allows an agent to read and write the flow JSON of a Node-RED instance (typically the Home Assistant add-on), so flows can be edited by the agent instead of by hand.
AlicenseAqualityAmaintenanceEnables MCP-speaking coding agents to talk directly to Home Assistant and the ESPHome dashboard: discovering entities and areas, reading live states, history and logs, rendering Jinja templates, calling services, and creating, editing or triggering automations and dashboards. Also allows ESPHome device configs to be read, validated, compiled and flashed, with all write operations off by default behind an explicit safety policy.111275 npmMITWhy this server?
Allows managing Node-RED through its Admin API, including listing, adding, and deploying flows, installing nodes, and injecting messages.
AlicenseBqualityBmaintenanceEnables MCP clients to control an infra-TAK host, including marketplace modules, Node-RED flows, MediaMTX video, TAK video publishing, and Docker operations via local APIs.19MITWhy this server?
Allows AI assistants to interact with Node-RED for flow management, including reading flows, searching nodes, editing function code, deploying changes safely, and managing modules via the Node-RED Admin API.
AlicenseAqualityDmaintenanceLets AI assistants interact with Node-RED to read flows, search nodes, edit function code, deploy changes safely, and manage modules.131MITWhy this server?
Allows AI agents to interact with a Node-RED instance, providing tools for managing flows, nodes, tabs, backups, settings, and triggering injections, enabling automated workflow management and deployment.
AlicenseBqualityDmaintenanceModel Context Protocol (MCP) server for Node-RED that allows language models to interact with Node-RED through a standardized API.2718 npm4MITWhy this server?
Connects Node-RED to the arche mcp server for offline automation flows, without network access or actuator loops.

AlicenseNot gradedqualityBmaintenanceServes an offline knowledge base — an aggregated corpus of reference works plus a RAG index over them and the user's own documents — to any local AI model over MCP. Enables offline assistants such as Open WebUI, OpenCode, or Jan to ground answers in searchable, provenance-tracked local content without any network connection.102 npmMITWhy this server?
Provides tools to manage Node-RED flows, nodes, settings, and runtime state, enabling language models to interact with and control Node-RED instances programmatically.
AlicenseDqualityFmaintenanceModel Context Protocol (MCP) server for Node-RED — allows language models (like Claude, GPT) to interact with Node-RED through a standardized API.20545 npm39MIT
