List all tables in the model.
AI agents call get_tables to retrieve information from PBIXRay 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 metadata about tables present in a Power BI data model without creating, modifying, executing, or deleting any data. It is a passive query operation that returns information only. The blast radius of misuse is minimal—an agent listing tables gains knowledge of the model structure but cannot alter or harm the system.
From the tool's definition Tool name 'get_tables' and description 'List all tables in the model' indicate a retrieval operation with no modification, deletion, or execution of code. The verb 'List' is explicitly a read operation.
Attacks that exploit this kind of access
List all tables in the model. It is categorised as a Read tool in the PBIXRay MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PBIXRay MCP Server MCP server in PolicyLayer and add a rule for get_tables: 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 PBIXRay MCP Server. Nothing to install.
get_tables 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 get_tables 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 get_tables. 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.
get_tables is provided by the PBIXRay MCP Server MCP server (ngoc0610/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
