WHAT IT DOES

What create_forwarding_rule does on Vultr MCP

AI agents use create_forwarding_rule 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 create_forwarding_rule is rated Medium

This tool creates a new network forwarding rule, which is a reversible write operation that modifies infrastructure configuration. While the empty description limits certainty, the 'create_' prefix and Vultr context (networking service) clearly indicate it writes/creates new resources rather than reading, executing arbitrary code, or destructively deleting data.

From the tool's definition Tool name 'create_forwarding_rule' indicates creation of a network forwarding rule. The prefix 'create_' explicitly indicates a write operation that adds new configuration to Vultr infrastructure.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_forwarding_rule 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 create_forwarding_rule, this is the rule to start with:

create_forwarding_rule Rate-limited

create_forwarding_rule 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.
