RISK

Why neuron_get_channel_qr is rated Low

This tool retrieves an existing QR code that was previously generated by a session startup process. It performs a query/fetch operation with no ability to modify data, execute commands, or cause destructive changes. The QR code itself is a read-only artifact. The severity is low because misuse would only expose a pairing QR code, which has limited security impact on its own.

From the tool's definition Tool is described as 'Retrieve the current QR code' - the verb 'Retrieve' and use of 'get' in the tool name indicate data retrieval with no side effects. The QR code is informational output for pairing purposes.
