WHAT IT DOES

What convert_instance_ip does on Vultr MCP

AI agents use convert_instance_ip 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 convert_instance_ip is rated Medium

The tool converts or modifies an instance's IP address assignment, which is a data modification (Write category) rather than destructive, as IP changes are typically reversible. Confidence is moderate due to the missing description; if the tool can forcibly reassign IPs causing service disruption, severity could escalate to high.

From the tool's definition Tool name 'convert_instance_ip' suggests modifying instance IP configuration. With empty description, inferred from context: sibling tools like 'add_ip_whitelist_entry' and 'add_export' indicate this server performs infrastructure modifications.

RECOMMENDED RULE

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

convert_instance_ip Rate-limited

convert_instance_ip 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.
