WHAT IT DOES

What update_vpc2 does on Vultr MCP

AI agents use update_vpc2 to create or update resources in Vultr MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Vultr MCP environment.

RISK

Why update_vpc2 is rated Medium

This tool modifies VPC metadata (the description field) in Vultr's cloud infrastructure. Updates are reversible—the description can be changed again or reverted. The blast radius is medium because incorrect VPC description updates could cause operational confusion or misconfiguration of network infrastructure, but do not cause data loss or execute arbitrary code.

From the tool's definition Tool name 'update_vpc2' and description 'Update VPC 2.0 description' indicate modification of existing VPC configuration data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_vpc2 safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Vultr MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_vpc2, this is the rule to start with:

update_vpc2 Rate-limited

update_vpc2 stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
