WHAT IT DOES

What list_database_types does on Linode MCP Server

AI agents call list_database_types to retrieve information from Linode MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_database_types is rated Low

This tool performs a simple enumeration/listing of database types, which is a pure Read operation. It retrieves information from the Linode API with no ability to modify, delete, or execute any resources. The blast radius of misuse is minimal—an AI agent can only discover what database types are available, which is informational only.

From the tool's definition Tool name 'list_database_types' and description 'Get a list of all available database types' indicate a read-only retrieval operation that queries available database type information without modification or side effects.

list_database_types Allowed

list_database_types is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
