THE RISK

Critical Risk

Why logout needs a policy

This tool irreversibly clears/destroys the stored authentication token. While not deleting user data, clearing auth credentials is a destructive, non-reversible action that cannot be undone (the token is gone and a new login would be required). It could disrupt an AI agent's ability to continue authenticated operations.

POLICY

How to control logout

PolicyLayer is an MCP gateway — it sits between your AI agents and Todo MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for logout:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "logout"
  ]
}

logout disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Todo MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on logout? +

Register the Todo MCP Server 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 Todo MCP Server. Nothing to install.

What risk level is logout? +

How do I block logout completely? +

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.

What MCP server provides logout? +

logout is provided by the Todo MCP Server MCP server (sholajegede/todo_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Todo MCP Server tool call.

Start from Todo MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
