## What is this?

**ac-infinity-mcp** is an [MCP server](https://modelcontextprotocol.io) 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](https://github.com/jlowin/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+ | ✅ | ⚠️ v1 read-only | New AI+ protocol — write support planned for v2 |

> ✦ All write tools (Write, Automation, and Intelligence categories) default to `dry_run=True` — they return the exact payload they *would* send without making any changes to your equipment. Pass `dry_run=False` only when you're ready to execute.

## MCP Prompts

Three built-in prompts are registered alongside the tools. In Claude Desktop and other MCP clients, these appear as slash commands or prompt suggestions.

| Prompt | What it does |
|---|---|
| `vpd_troubleshooting` | Step-by-step guide: diagnose HIGH or LOW VPD and which tools to call to fix it |
| `new_grower_setup` | Onboarding walkthrough: discover devices → apply a stage template → check your health score |
| `environment_alert_interpretation` | How to read `check_vpd_drift` status values and `get_environment_health` grades (A–F, score weighting, what to do) |

## Quick start

### Option 1: pip (simplest)

```bash
pip install git+https://github.com/ober37/ac-infinity-mcp.git
```

Requires Python 3.11+.

### Option 2: isolated venv (recommended)

```bash
python3 -m venv ~/.venvs/ac-infinity-mcp
source ~/.venvs/ac-infinity-mcp/bin/activate
pip install git+https://github.com/ober37/ac-infinity-mcp.git
which ac-infinity-mcp   # copy this path — you'll need it below
```

### Option 3: uvx (no install)

```bash
uvx --from git+https://github.com/ober37/ac-infinity-mcp.git ac-infinity-mcp
```

## MCP client configuration

### Claude Desktop

Edit `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS) or
`%APPDATA%\Claude\claude_desktop_config.json` (Windows):

```json
{
  "mcpServers": {
    "ac-infinity": {
      "command": "/path/to/ac-infinity-mcp",
      "env": {
        "AC_INFINITY_EMAIL": "you@example.com",
        "AC_INFINITY_PASSWORD": "yourpassword"
      }
    }
  }
}
```

Replace `/path/to/ac-infinity-mcp` with the path printed by `which ac-infinity-mcp`.

### Cursor / Windsurf

Add to your MCP settings:

```json
{
  "ac-infinity": {
    "command": "/path/to/ac-infinity-mcp",
    "env": {
      "AC_INFINITY_EMAIL": "you@example.com",
      "AC_INFINITY_PASSWORD": "yourpassword"
    }
  }
}
```

## Docker

```bash
cp .env.example .env
# fill in AC_INFINITY_EMAIL and AC_INFINITY_PASSWORD
docker compose up --build
```

The container runs over stdio. Connect via a stdio bridge such as [mcp-proxy](https://github.com/sparfenyuk/mcp-proxy).

> Credentials are injected at runtime via `env_file` — never baked into the image.

## Environment variables

| Variable | Required | Description |
|---|---|---|
| `AC_INFINITY_EMAIL` | Yes | Your AC Infinity account email |
| `AC_INFINITY_PASSWORD` | Yes | Your AC Infinity account password |

> ⚠️ **HTTP-only upstream:** The AC Infinity cloud API does not support HTTPS. Credentials and sensor data traverse the network in plain text. This is an upstream limitation — see [docs/API.md](https://github.com/ober37/ac-infinity-mcp/blob/HEAD/docs/API.md) Quirk 8. Avoid running this server on untrusted networks.

## Development

```bash
git clone https://github.com/ober37/ac-infinity-mcp.git
cd ac-infinity-mcp
python3 -m venv .venv && source .venv/bin/activate
pip install -e ".[dev]"
cp .env.example .env   # fill in credentials

# Lint + type-check
ruff check src/ tests/
mypy src/ac_infinity_mcp/

# Tests (unit + integration)
pytest tests/ -v

# Security audit
pip-audit
```
