Get detailed Last.fm information about any track (artist, album, play count, tags, similar tracks) - No authentication required

This tool retrieves public music metadata from Last.fm without modifying any data, triggering external operations, or requiring authentication. It performs a straightforward query operation that returns information about tracks. The lack of authentication requirement and focus on data retrieval (play count, tags, similar tracks) confirms this is a Read operation with minimal risk if misused by an AI agent.
From the tool's definition Tool description explicitly states it 'Get[s] detailed Last.fm information about any track' with read-only operations (artist, album, play count, tags, similar tracks) and 'No authentication required', indicating pure data retrieval with no side effects.

"tools": {
"get_track_info": {}
}
}get_track_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
