End a specific Gemini consultation session to free up memory.
AI agents call end_session to permanently remove resources in Automagik Tools — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Ending a session frees associated memory and state, which cannot be recovered once destroyed. This is an irreversible action that destroys a resource (the session), making it Destructive. However, the blast radius is limited since it only affects a single consultation session, not persistent data, hence medium severity.
From the tool's definition 'End a specific Gemini consultation session to free up memory' — terminates/destroys a session state irreversibly
Documented attack patterns abuse exactly the kind of access end_session gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Automagik Tools, and nothing reaches the server without passing your rules. This is the rule we recommend for end_session:
{
"version": "1",
"default": "deny",
"hide": [
"end_session"
]
}end_session disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

End a specific Gemini consultation session to free up memory. It is categorised as a Destructive tool in the Automagik Tools MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Automagik Tools MCP server in PolicyLayer and add a rule for end_session: 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 Automagik Tools. Nothing to install.
end_session 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 end_session 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 end_session. 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.
end_session is provided by the Automagik Tools MCP server (namastexlabs/automagik-tools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Automagik Tools, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
