Validate email address format and check if the domain has valid MX records. Works without external APIs.
AI agents call validate_email to retrieve information from GOD MODE INTEL MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves DNS/domain information to validate email addresses. It has no side effects, creates no data, executes no commands, and cannot delete or modify anything. It is purely informational verification, fitting squarely in the Read category with minimal risk.
From the tool's definition Tool performs email validation and MX record checking - operations that query and verify information without modifying, executing, or deleting anything. The description explicitly states it 'validate[s]' and 'check[s]', which are read-only operations.
Attacks that exploit this kind of access
Validate email address format and check if the domain has valid MX records. Works without external APIs. It is categorised as a Read tool in the GOD MODE INTEL MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GOD MODE INTEL MCP Server MCP server in PolicyLayer and add a rule for validate_email: 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 GOD MODE INTEL MCP Server. Nothing to install.
validate_email is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the validate_email 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 validate_email. 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.
validate_email is provided by the GOD MODE INTEL MCP Server MCP server (johnrippy1980/god-mode-intel-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
