List data sources published on a site.
AI agents call list_datasources to retrieve information from Tableau MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or enumerates data sources without creating, modifying, deleting, or executing operations. It is a straightforward read operation that queries Tableau metadata. Low severity because listing datasources poses minimal risk—it discloses available resources but cannot alter data or systems.
