WHAT IT DOES

What list_ssh_keys does on Linode MCP Server

AI agents call list_ssh_keys 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_ssh_keys is rated Low

This tool queries and returns existing SSH keys without creating, modifying, deleting, or executing anything. It is a read-only operation with minimal security impact, as it simply enumerates data the user already owns. Severity is low because SSH key listings do not directly enable system compromise on their own, though the information could inform further attacks.

From the tool's definition Tool name is 'list_ssh_keys' and description states 'List SSH keys associated with your profile' — a retrieval operation with no modification or side effects.
