Get the policy of a bucket
AI agents call object_get_bucket_policy to retrieve information from Zadara Storage MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a Read operation—it retrieves bucket policy metadata. Severity is medium rather than low because bucket policies contain authorization rules that, if exposed to an unauthorized agent, could reveal access control configurations, authentication secrets, or patterns that facilitate privilege escalation attacks. However, the tool itself performs no destructive, financial, or executable action.
From the tool's definition Tool name 'object_get_bucket_policy' with description 'Get the policy of a bucket' indicates retrieval of existing data (bucket policy configuration) without modification or deletion.

Register the Zadara Storage MCP Server MCP server in PolicyLayer and add a rule for object_get_bucket_policy: 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 Zadara Storage MCP Server. Nothing to install.
object_get_bucket_policy 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 object_get_bucket_policy 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 object_get_bucket_policy. 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.
object_get_bucket_policy is provided by the Zadara Storage MCP Server MCP server (zadarastorage/zadara-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
