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 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.

Retrieves a list of published data sources from a specified Tableau site using the Tableau REST API. Supports optional filtering via field:operator:value expressions (e.g., name:eq:Views) for precise and flexible data source discovery. Use this tool when a user requests to list, search, or filter Tableau data sources on a site. Supported Filter Fields and Operators | Field | Operators | |------------------------|-------------------------------------------| | authenticationType | eq, in | | connectedWorkbookType | eq, gt, gte, lt, lte | | connectionTo | eq, in | | connectionType | eq, in | | contentUrl | eq, in | | createdAt | eq, gt, gte, lt, lte | | databaseName | eq, in | | databaseUserName | eq, in | | description | eq, in | | favoritesTotal | eq, gt, gte, lt, lte | | hasAlert | eq | | hasEmbeddedPassword | eq | | hasExtracts | eq | | isCertified | eq | | isConnectable | eq | | isDefaultPort | eq | | isHierarchical | eq | | isPublished | eq | | name | eq, in | | ownerDomain | eq, in | | ownerEmail | eq | | ownerName | eq, in | | projectName* | eq, in | | serverName | eq, in | | serverPort | eq | | size | eq, gt, gte, lt, lte | | tableName | eq, in | | tags | eq, in | | type | eq | | updatedAt | eq, gt, gte, lt, lte | ${genericFilterDescription} Example Usage: - List all data sources on a site - List data sources with the name. It is categorised as a Read tool in the Tableau MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Tableau MCP Server MCP server in PolicyLayer and add a rule for list-datasources: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Tableau MCP Server. Nothing to install.
list-datasources is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list-datasources rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list-datasources. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list-datasources is provided by the Tableau MCP Server MCP server (tableau/tableau-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
