identity-oidc-key-delete
AI agents call identity-oidc-key-delete to permanently remove resources in Vault MCP Server (mschuchard) — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes OIDC identity keys from Vault. OIDC keys are critical for OpenID Connect authentication flows and their deletion cannot be undone. The absence of a description raises confidence only slightly lower than if documented, but the 'delete' verb combined with the Vault context and sensitivity of OIDC key material (used in authentication systems) makes this clearly Destructive rather than…
From the tool's definition Tool name contains 'delete' and operates on identity OIDC keys within HashiCorp Vault. The sibling tools pattern (audit-device-disable, authentication-engine-disable, database-connection-delete) shows this server manages sensitive security infrastructure.

Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Vault MCP Server (mschuchard). Nothing to install.
identity-oidc-key-delete is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the identity-oidc-key-delete rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for identity-oidc-key-delete. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
