AI agents talking to real BLE devices (via Bleak + MCP)

[es617]

I’ve been using Bleak for years for prototyping and testing BLE devices, and recently built a small open-source tool on top of it that lets AI agents (via MCP) talk directly to real BLE hardware.

The idea is simple: give the agent the same tools you'd use — scan, connect, read, write, subscribe — and let it interact with real devices. That means AI sitting in the debug loop alongside you, poking at services, reading and writing data — but also automating test sequences, exploring unfamiliar devices, or just letting AI interact with the devices around us.

I was honestly impressed by how straightforward it was to build this on top of Bleak — the API design made it pretty painless.

Repo + write-up here if anyone’s curious:

• GitHub: https://github.com/es617/ble-mcp-server
• Blog: https://es617.dev/2026/02/10/ble-mcp-server.html

And, thanks for Bleak — it made this kind of experiment way easier than it would have been otherwise.

Very cool, thanks for sharing.

And when the AI bots take over all the Bluetooth devices, we will know who to blame!
