AI agents call get_csql_operation to retrieve information from Storage without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves the status of an existing Cloud SQL operation. It performs a read-only operation that returns information about an operation's progress or state without creating, modifying, deleting, or executing any resources. The blast radius of misuse is minimal—an agent could only obtain information about Cloud SQL operations already in progress.
From the tool's definition Tool name 'get_csql_operation' and description 'Gets the status of a Cloud SQL operation' indicate retrieval of operational status information with no modification or deletion of data.
Attacks that exploit this kind of access
Gets the status of a Cloud SQL operation. It is categorised as a Read tool in the Storage MCP Server, which means it retrieves data without modifying state.
Register the Storage MCP server in PolicyLayer and add a rule for get_csql_operation: 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 Storage. Nothing to install.
get_csql_operation 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_csql_operation 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_csql_operation. 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_csql_operation is provided by the Storage MCP server (@google-cloud/storage-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
