AI agents call get_bucket_storage_info to retrieve information from Gcp Storage without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves storage metadata (usage statistics) from a GCP bucket. It has no side effects, does not modify data, does not execute code, and does not delete or move resources. It is purely informational, fitting the 'Read' category as a simple data retrieval operation.
From the tool's definition Tool name 'get_bucket_storage_info' and description 'Get storage usage information for a bucket' indicate a read-only query operation that retrieves metrics about bucket storage without modifying, executing, or deleting any data.
Documented attack patterns abuse exactly the kind of access get_bucket_storage_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Gcp Storage, and nothing reaches the server without passing your rules. This is the rule we recommend for get_bucket_storage_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_bucket_storage_info": {}
}
}get_bucket_storage_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get storage usage information for a bucket. It is categorised as a Read tool in the Gcp Storage MCP Server, which means it retrieves data without modifying state.
Register the Gcp Storage MCP server in PolicyLayer and add a rule for get_bucket_storage_info: 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 Gcp Storage. Nothing to install.
get_bucket_storage_info 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_bucket_storage_info 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_bucket_storage_info. 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_bucket_storage_info is provided by the Gcp Storage MCP server (uysalserkan/gcp-storage-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Gcp Storage, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
