Gets the location and storage class of a bucket.
AI agents call get_bucket_location to retrieve information from Observability without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query to fetch bucket metadata (location and storage class). It has no side effects, cannot modify or delete data, and poses minimal risk if invoked by an AI agent. The blast radius is limited to information disclosure of non-sensitive bucket configuration details.
From the tool's definition Tool name 'get_bucket_location' and description 'Gets the location and storage class of a bucket' indicate a query operation that retrieves metadata about an existing bucket without modifying or deleting data.
Attacks that exploit this kind of access
Gets the location and storage class of a bucket. It is categorised as a Read tool in the Observability MCP Server, which means it retrieves data without modifying state.
Register the Observability MCP server in PolicyLayer and add a rule for get_bucket_location: 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 Observability. Nothing to install.
get_bucket_location 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_location 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_location. 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_location is provided by the Observability MCP server (@google-cloud/observability-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
