AI agents call get_datasets to retrieve information from Bq without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves dataset metadata without modifying or executing operations. The server explicitly describes it as part of metadata retrieval functionality. No side effects or data modification occurs. This is a straightforward Read operation with minimal risk of misuse.
From the tool's definition Tool name 'get_datasets' combined with server description stating the tool 'retrieves and caches BigQuery metadata (datasets, tables, columns)' indicates this is a data retrieval operation.
Attacks that exploit this kind of access
get_datasets. It is categorised as a Read tool in the Bq MCP Server, which means it retrieves data without modifying state.
Register the Bq MCP server in PolicyLayer and add a rule for get_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 Bq. Nothing to install.
get_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 get_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 get_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.
get_datasets is provided by the Bq MCP server (takada-at/bq_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
