AI agents call scan_domain to retrieve information from Intodns without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs DNS and email security queries and analysis, returning structured results (grades, scores, issues, recommendations, and DNS/email/web/security data). It is explicitly documented as read-only with no side effects. It retrieves and reports information about a domain's security posture without creating, modifying, or deleting any data.
From the tool's definition Tool description explicitly states: 'Read-only — no domain mutation, no destructive side effects' and 'Run the fast IntoDNS.ai DNS and email security scan' which retrieves and analyzes DNS records and email security configuration without modifying anything.
Attacks that exploit this kind of access
Run the fast IntoDNS.ai DNS and email security scan (~3-8s). Returns a letter grade A+ to F, numeric score 0-100, structured issue list, prioritised recommendations, full DNS/email/web/security result sections, and canonical citation URLs. Read-only — no domain mutation, no destructive side effects. The default tool for agent-visible scan evidence; use get_everything_report for a deeper single-shot report including web/blacklist/sender data, or start_deep_scan for slower Internet.nl-grade analysis. After running, use explain_issue or generate_dns_fix on any returned issue. No auth. It is categorised as a Read tool in the Intodns MCP Server, which means it retrieves data without modifying state.
Register the Intodns MCP server in PolicyLayer and add a rule for scan_domain: 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 Intodns. Nothing to install.
scan_domain 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 scan_domain 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 scan_domain. 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.
scan_domain is provided by the Intodns MCP server (rosconl/intodns-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
