WHAT IT DOES

What update_oauth_client does on Linode MCP Server

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

RISK

Why update_oauth_client is rated Medium

This tool modifies OAuth client settings, which could include credentials, redirect URIs, scopes, or other security-sensitive configuration. While reversible (unlike destructive operations), unauthorized updates could compromise authentication/authorization flows, enable token hijacking, or grant unintended access. The high severity reflects the security-critical nature of OAuth client configuration.

From the tool's definition Tool name is 'update_oauth_client' and description states 'Update an OAuth client'. The verb 'update' indicates modification of existing data (OAuth client credentials/configuration).
