What list-datasources does on Tableau MCP Server

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.

Why list-datasources needs a policy

This tool performs read-only data retrieval operations. It queries the Tableau REST API to list and filter datasources but does not create, modify, delete, or execute any operations. The filtering capability is a search/discovery feature, not a write or destructive action. Blast radius is minimal: an agent could discover datasources but cannot alter or harm them directly through this tool alone.

From the tool's definition Tool 'Retrieves a list of published data sources' with 'optional filtering via field:operator:value expressions for data source discovery'. No modification, deletion, or execution of operations—purely querying and listing existing Tableau datasources.
