Retrieve available tables and columns from a Power BI dataset schema (model.bim).
AI agents call get_dataset_schema to retrieve information from powerBI-mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward read operation that introspects schema metadata. It retrieves information about dataset structure without side effects. While data schema information could theoretically be sensitive, the blast radius of misuse is minimal—an AI agent cannot cause damage by reading schema metadata alone. The tool is appropriately classified as Read with low severity.
From the tool's definition Tool retrieves/queries available tables and columns from a Power BI dataset schema (model.bim) with no modification, deletion, or execution capability implied.
Attacks that exploit this kind of access
Retrieve available tables and columns from a Power BI dataset schema (model.bim). It is categorised as a Read tool in the powerBI-mcp MCP Server, which means it retrieves data without modifying state.
Register the powerBI- MCP server in PolicyLayer and add a rule for get_dataset_schema: 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 powerBI-mcp. Nothing to install.
get_dataset_schema 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_dataset_schema 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_dataset_schema. 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_dataset_schema is provided by the powerBI- MCP server (ramandimbinirina/powerbi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
