List all datasets in the configured BigQuery project.
AI agents call list_datasets to retrieve information from Mcp Bigquery Evals without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns metadata about datasets without modifying, deleting, or executing any operations. It is a pure read operation that merely enumerates existing resources. The blast radius is minimal—exposing dataset names could leak schema information but poses no direct risk of data loss, execution, or financial impact. Low severity is appropriate for passive metadata inspection.
From the tool's definition Tool name 'list_datasets' and description 'List all datasets in the configured BigQuery project' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
List all datasets in the configured BigQuery project. It is categorised as a Read tool in the Mcp Bigquery Evals MCP Server, which means it retrieves data without modifying state.
Register the Mcp Bigquery Evals MCP server in PolicyLayer and add a rule for list_datasets: 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 Mcp Bigquery Evals. Nothing to install.
list_datasets 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_datasets 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_datasets. 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_datasets is provided by the Mcp Bigquery Evals MCP server (umarfarook1/mcp-bigquery-evals). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
