AI agents call get_oceanbase_cluster_snapshots to retrieve information from Mcp Oceanbase without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only query operation that retrieves snapshot metadata from an OceanBase cluster. It has no side effects, does not modify data, and merely returns information about existing snapshots. The permission requirement ('read and write permissions') refers to access control for the cluster, not the nature of the operation itself, which is purely informational.
From the tool's definition Tool name contains 'get_' and description states 'Query cluster snapshot information' and 'Query snapshot information'. Returns snapshot list with metadata (snapshotId, snapshotTime). No modification, deletion, or execution of operations.

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Oceanbase, and nothing reaches the server without passing your rules. This is the rule we recommend for get_oceanbase_cluster_snapshots:
{
"version": "1",
"default": "deny",
"tools": {
"get_oceanbase_cluster_snapshots": {}
}
}get_oceanbase_cluster_snapshots is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Query cluster snapshot information Query snapshot information of a specified cluster. The caller must have read and write permissions for the specified cluster. Args: cluster_id: The ID of the target OceanBase cluster (required) Returns: Dictionary containing snapshot list. Each snapshot includes: - snapshotId: Snapshot ID - snapshotTime: Snapshot creation time. It is categorised as a Read tool in the Mcp Oceanbase MCP Server, which means it retrieves data without modifying state.
Register the Mcp Oceanbase MCP server in PolicyLayer and add a rule for get_oceanbase_cluster_snapshots: 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 Mcp Oceanbase. Nothing to install.
get_oceanbase_cluster_snapshots 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_oceanbase_cluster_snapshots 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_oceanbase_cluster_snapshots. 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_oceanbase_cluster_snapshots is provided by the Mcp Oceanbase MCP server (oceanbase/awesome-oceanbase-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
