HTML page: https://policylayer.com/tools/eaveluo-1panel-mcp/update-fail2ban-conf-by-file ## Facts - Tool: `update_fail2ban_conf_by_file` - Server: 1Panel MCP Server (`eaveluo/1panel-mcp`) — https://policylayer.com/tools/eaveluo-1panel-mcp.md - Homepage: https://github.com/EaveLuo/1panel-mcp - Risk category: Write (Medium 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": "update_fail2ban_conf_by_file", "arguments": {} } } ``` ## Why update_fail2ban_conf_by_file is rated Medium This tool creates or modifies Fail2ban configuration files, which is a reversible write operation. However, it carries high severity because misconfiguration of Fail2ban (an intrusion prevention system) could disable security protections, lock out legitimate users, or inadvertently allow malicious traffic. From the tool's own definition: "Tool name 'update_fail2ban_conf_by_file' and description 'Update Fail2ban configuration by file content' indicate modification of Fail2ban security configuration files." ## Use case AI agents use update_fail2ban_conf_by_file to create or update resources in 1Panel MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 1Panel MCP Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
