Log out and clear stored credentials
AI agents call logout to permanently remove resources in Talon — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Logging out and clearing stored credentials is an irreversible action that destroys the current session and removes saved authentication data. There is no 'undo' for a logout; the user must re-authenticate. This maps best to Destructive rather than Write because the credentials/session are permanently removed, not merely modified.
From the tool's definition 'Log out and clear stored credentials' — irreversibly clears stored credentials/session state
Attacks that exploit this kind of access
Log out and clear stored credentials. It is categorised as a Destructive tool in the Talon MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Talon MCP server in PolicyLayer and add a rule for 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 Talon. Nothing to install.
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 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 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.
logout is provided by the Talon MCP server (talon-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
