Get schema information for a dataset
AI agents call get_dataset_schema to retrieve information from PowerBI 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 schema metadata (column names, types, relationships) from an existing dataset. It performs no modifications, executions, or deletions. The action is informational only, making it a Read operation with low severity due to minimal blast radius if misused—an agent could only gather information about dataset structure.
From the tool's definition Tool name 'get_dataset_schema' and description 'Get schema information for a dataset' indicate a retrieval operation that queries metadata without modifying data or triggering external operations.
Attacks that exploit this kind of access
Get schema information for a dataset. It is categorised as a Read tool in the PowerBI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PowerBI MCP Server 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 Server. 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 MCP server (pkduongsu/powerbi-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
