Return view data as CSV. filters maps field names to value filters.
AI agents call query_view_data 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 and exports view data in CSV format. It is a read-only operation that queries existing data without creating, modifying, deleting, or executing code. No side effects or irreversible actions occur. The low severity reflects minimal blast radius if misused—an AI agent could access data it shouldn't, but cannot modify or destroy anything.
From the tool's definition Tool name 'query_view_data' and description 'Return view data as CSV' explicitly indicate data retrieval with no modification. The filters parameter allows querying but does not alter data.
Attacks that exploit this kind of access
Return view data as CSV. filters maps field names to value filters. 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 query_view_data: 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.
query_view_data 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 query_view_data 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 query_view_data. 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.
query_view_data is provided by the Tableau MCP Server MCP server (lokimcpuniverse/tableau-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
