## Why mb_search_releases is rated Low

This tool performs a search query against the MusicBrainz database to retrieve information about musical releases and albums. It is a read-only operation that retrieves existing data with no capability to modify, delete, or execute code. The blast radius of misuse is minimal—an agent could retrieve unwanted data but cannot cause harm to systems or data integrity.

From the tool's own definition: "Tool name 'mb_search_releases' and description 'Search for releases/albums on MusicBrainz' indicate a query operation that retrieves data without side effects."

Risk signals: Accepts freeform code/query input (query)

## Use case

AI agents call mb_search_releases to retrieve information from UnClick without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
