Delete entire terminal session (including terminal itself). WARNING: This deletes the terminal, if you only want to stop command use interrupt_command
AI agents call kill_session to permanently remove resources in Ai Mcp Terminal — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool destroys a terminal session permanently without recovery options. While not data-deletion in the traditional sense, it irreversibly terminates an execution environment and any unsaved state within it. This matches Destructive (cannot be undone) rather than Execute (which would be reversible via session restart).
From the tool's definition "Delete entire terminal session (including terminal itself)" - irreversibly removes the terminal and all associated state/context. The warning explicitly distinguishes this from interrupt_command, confirming deletion semantics.

Delete entire terminal session (including terminal itself). WARNING: This deletes the terminal, if you only want to stop command use interrupt_command. It is categorised as a Destructive tool in the Ai Mcp Terminal MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Ai Mcp Terminal MCP server in PolicyLayer and add a rule for kill_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 Ai Mcp Terminal. Nothing to install.
kill_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 kill_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 kill_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.
kill_session is provided by the Ai Mcp Terminal MCP server (kanniganfan/ai-mcp-terminal). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
