Delete a join (relationship) between two sources in a Birst space. Requires specifying the exact join properties to identify which join to delete.
AI agents call birst_delete_join to permanently remove resources in Infor Birst MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes join definitions that establish relationships between data sources. While not as immediately catastrophic as deleting entire tables, removing joins breaks data model integrity and cannot be easily undone without administrative recovery or recreation of the join logic.
From the tool's definition The tool name explicitly contains 'delete' and the description states it 'Delete[s] a join (relationship) between two sources in a Birst space.' Deletion of database schema elements (joins/relationships) is irreversible structural modification.
