List all disk snapshots
AI agents call list_disk_snapshots to retrieve information from Yandex Cloud MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates existing disk snapshots without creating, modifying, or deleting any resources. It has no side effects beyond information disclosure. The blast radius of misuse is minimal—an attacker could view snapshot metadata but cannot alter infrastructure or data. Low severity due to read-only nature and informational output only.
From the tool's definition Tool name 'list_disk_snapshots' and description 'List all disk snapshots' indicate a query/retrieval operation. Server is explicitly described as 'Read-only MCP server'.

Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Yandex Cloud MCP Server. Nothing to install.
list_disk_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 list_disk_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 list_disk_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.
