Sign out and clear all stored credentials (in-memory tokens and persisted refresh tokens).
AI agents call auth_logout to permanently remove resources in CIB Seven MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly clears authentication credentials including persisted refresh tokens. While it doesn't delete business data, it destroys session state and stored tokens in a way that cannot be undone, potentially disrupting ongoing operations and requiring re-authentication. The clearing of persisted tokens makes this irreversible without re-login.

Attacks that exploit this kind of access
Sign out and clear all stored credentials (in-memory tokens and persisted refresh tokens). It is categorised as a Destructive tool in the CIB Seven MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the CIB Seven MCP Server MCP server in PolicyLayer and add a rule for auth_logout: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches CIB Seven MCP Server. Nothing to install.
auth_logout 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 auth_logout 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 auth_logout. 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.
auth_logout is provided by the CIB Seven MCP Server MCP server (krixerx/cib7-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
