# disable_greylisting Disable greylisting for all domains Agent View of the PolicyLayer registry record for `disable_greylisting`. HTML page: https://policylayer.com/tools/0xhayd3n-cpanel-mcp-server/disable-greylisting ## Facts - Tool: `disable_greylisting` - Server: cPanel MCP Server (`0xhayd3n/cpanel-mcp-server`) — https://policylayer.com/tools/0xhayd3n-cpanel-mcp-server.md - Homepage: https://github.com/0xHayd3n/cPanel-MCP-Server - 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": "disable_greylisting", "arguments": {} } } ``` ## Why disable_greylisting is rated Medium This tool changes email server configuration across all domains by disabling a spam-filtering mechanism. The action is reversible (greylisting can be re-enabled), so it is Write rather than Destructive. The severity is medium because disabling greylisting reduces email security and increases spam delivery risk, potentially affecting multiple domains and email users, but the change is not permanent and can be undone. From the tool's own definition: "Tool name and description indicate it modifies email security settings ('Disable greylisting for all domains'). Greylisting is a reversible email filter configuration that can be re-enabled." ## Use case AI agents use disable_greylisting to create or update resources in cPanel MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your cPanel MCP Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
