WHAT IT DOES

What secret-engine-tune-configuration does on Vault MCP Server (mschuchard)

AI agents use secret-engine-tune-configuration to create or update resources in Vault MCP Server (mschuchard) — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Vault MCP Server (mschuchard) environment.

WHY IT NEEDS A POLICY

Why secret-engine-tune-configuration needs a policy

Based on naming convention, 'tune' in Vault typically means modifying configuration parameters of an existing secret engine (e.g., TTLs, audit settings). This is a Write operation that modifies existing configuration rather than deleting it. However, misconfiguration of a secret engine could have significant security implications (e.g., extending TTLs, changing access controls), justifying high severity.
