Overview
The Pi Zero 2 W is too small to host a primary agent in 2026, but it shines as an edge endpoint. Pair it with a primary host (Pi 5, mini PC, Mac Mini) and have the Zero serve as an MCP tool host — read sensors, control GPIO, run small local utilities. €20 is cheap enough that you can scatter five of them across a workspace and have them act as the hands and eyes of a single primary agent. This is genuinely the right place to be experimentally.
