End the current authentication session and clean up session data. Removes session from server storage and clears authentication state. Safe to call even when not authenticated.
AI agents call logout to retrieve information from Session-Based Authenticated MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though logout only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
End the current authentication session and clean up session data. Removes session from server storage and clears authentication state. Safe to call even when not authenticated. It is categorised as a Read tool in the Session-Based Authenticated MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Session-Based Authenticated 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 Session-Based Authenticated MCP Server. Nothing to install.
logout is a Read tool with low risk. Read-only tools are generally safe to allow by default.
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 Session-Based Authenticated MCP Server MCP server (omiderfanmanesh/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
logout is one line of Session-Based Authenticated MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
