ober37/ac-infinity-mcp

Control and monitor your AC Infinity grow environment through Claude and any MCP-compatible AI assistant.
---
What is this?
**ac-infinity-mcp** is an MCP server that connects Claude (and other AI assistants) directly to your AC Infinity controllers — so you can read live sensor data, run analytics, and adjust fan speeds or port states using natural language, without opening the AC Infinity app.
> Built with FastMCP and the AC Infinity cloud API.
Example prompts
> *"What's the VPD trend in my tent over the last 7 days?"*
> *"Is my environment in the right range for late flower?"*
> *"Turn off port 3 on my 69 Pro controller — dry run first."*
> *"Show me which ports have been running the most this week."*
> *"Apply the veg stage template to port 1 — dry run first so I can see the settings."*
> *"My VPD is too high — what should I adjust?"*
Compatible hardware
| Controller | Reads | Writes | Notes |
|---|---|---|---|
| UIS Controller 69 Pro | ✅ | ✅ | Legacy protocol |
| UIS Controller 69 Pro+ | ✅ | ✅ | Legacy protocol |
| UIS Controller 89 AI+ | ✅ | ✅ † | New AI+ protocol — port writes require the minversion header (Quirk 14) |
† Per-port writes (on/off, speed, mode, temperature/humidity/VPD automation) all work —
that is the scope of Quirk 14's minversion finding, which covers addDevMode only.
Multi-port **Advance Automations** are only partly verified on AI+: reads work, creates
and in-place edits have both landed on a devType 20 (#326), creates time out on a
different AI+ controller (#290), and enable/disable are unexercised on any AI+. Separately,
apply_grow_stage_template / break_out_of_automation are held back pending hardware
verification (#316) — both refuse with an explanation instead of writing. See
AI+ controllers.
