The AI can check my reef tank lights and pumps, but it cannot change them

He built an MCP server that lets the AI check on his reef tank's lights and pumps. It is read only, because he does not trust the AI or himself with the fish.

How it works

  1. Builds an MCP server for the tank gear
  2. The AI can read the lights and pumps through it
  3. Nothing on the tank can be changed from the AI’s side

Why it’s worth knowing

The point of the setup is what the AI cannot do. It can look at the tank all it wants and still never touch a pump.
