Lists available Power BI workspaces for the current user.
AI agents call list_powerbi_workspaces to retrieve information from Semantic Model 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 lists workspaces accessible to the authenticated user. It performs a read-only query operation with no side effects, data modification, code execution, or resource deletion. The blast radius of misuse is minimal—an attacker gains visibility into workspace names but cannot modify, execute, or destroy resources.
From the tool's definition Tool name 'list_powerbi_workspaces' and description 'Lists available Power BI workspaces for the current user' indicate a query/enumeration operation with no modification or execution of code.
Attacks that exploit this kind of access
Lists available Power BI workspaces for the current user. It is categorised as a Read tool in the Semantic Model MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Semantic Model MCP Server MCP server in PolicyLayer and add a rule for list_powerbi_workspaces: 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 Semantic Model MCP Server. Nothing to install.
list_powerbi_workspaces 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_powerbi_workspaces 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_powerbi_workspaces. 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_powerbi_workspaces is provided by the Semantic Model MCP Server MCP server (nahtheking/semantic-model-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
