# reverse_shell_stop Stop a reverse shell session. Agent View of the PolicyLayer registry record for `reverse_shell_stop`. HTML page: https://policylayer.com/tools/zebbern-zebbern-kali-mcp/reverse-shell-stop ## Facts - Tool: `reverse_shell_stop` - Server: Zebbern Kali MCP (`zebbern/zebbern-kali-mcp`) — https://policylayer.com/tools/zebbern-zebbern-kali-mcp.md - Homepage: https://github.com/zebbern/zebbern-kali-mcp - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "reverse_shell_stop", "arguments": {} } } ``` ## Why reverse_shell_stop is rated High This tool executes commands to halt active reverse shell sessions, which are typically established for remote code execution. While termination is less destructive than initiation, it still qualifies as Execute because it triggers external operations whose effects depend on which shell session is targeted. From the tool's own definition: "Tool name 'reverse_shell_stop' and description 'Stop a reverse shell session' indicate interaction with active reverse shell processes. Stopping a shell is an Execute-class action that terminates an external operation (the reverse shell connection)." ## Use case AI agents invoke reverse_shell_stop to trigger actions in Zebbern Kali MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
