List all security groups
AI agents call list_vpc_security_groups 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 queries and retrieves existing security group data from Yandex Cloud infrastructure. It has no side effects, cannot modify resources, and does not execute operations or trigger external actions. The read-only nature of the server and the list operation confirm this is purely informational retrieval.
From the tool's definition Tool name 'list_vpc_security_groups' performs a list operation. Server is explicitly described as 'Read-only MCP server' for Yandex Cloud resources. The tool retrieves security group configurations without modification or execution capabilities.
