Definition: DNSai is a developer and domain-analysis tool for looking up DNS records, WHOIS information, blacklist status, and email authentication settings such as SPF, DKIM, and DMARC. It presents results with plain-English summaries and offers access through a web interface, an API, and MCP connectors.

What does DNSai help users check?

DNSai brings together several common domain investigation tasks in one product. Users can inspect DNS records to understand how a domain is configured, review WHOIS data, check whether a domain appears on blacklists, and analyze the DNS-based policies that support email authentication.

The DNS record lookup function is relevant when investigating records such as those used for website routing, mail delivery, domain verification, and service configuration. Rather than requiring users to switch between separate lookup sites, DNSai is positioned as a central place to research a domain and interpret the available information.

Its email-focused analysis covers SPF, DKIM, and DMARC. These controls are important for understanding which systems may send email for a domain, how messages can be cryptographically authenticated, and what policy a domain publishes for handling messages that fail authentication checks. DNSai provides summaries intended to make these results easier to understand alongside the underlying lookup data.

• DNS record lookup for domain configuration research
• WHOIS lookup for domain registration information
• Blacklist checks for screening a domain
• SPF, DKIM, and DMARC analysis for email authentication review
• Plain-English summaries of lookup results

Who is DNSai designed for?

DNSai is aimed at developers, IT administrators, security teams, domain owners, and people building AI agent workflows. These groups often need to evaluate domains for different reasons, but they share a need for reliable access to DNS and domain-security information.

Developers can use DNSai while debugging DNS-related application issues or when building systems that need domain intelligence. IT administrators may use it to review mail-related DNS configuration and troubleshoot issues connected to domain records. Domain owners can use the tool to examine their own settings and assess whether published email authentication records are present.

Security teams can apply DNSai to threat and intelligence screening workflows. Blacklist checks, WHOIS data, and DNS configuration can all provide useful context during an investigation. The product also supports bulk scanning, which is relevant when a team needs to review more than one domain rather than conduct a single lookup.

For AI agent builders, DNSai provides MCP connectors. MCP support can make the product relevant to workflows where an AI system needs access to domain lookup capabilities. DNSai lists integrations with Claude, Perplexity, Manus, and Grok, indicating intended use alongside supported AI environments and tools.

How does DNSai make domain results easier to interpret?

Raw DNS and email-authentication records can be difficult to read, especially when users must distinguish between valid configuration, missing records, and records that may not meet their intended purpose. DNSai supplements its lookup outputs with plain-English summaries.

These summaries are intended to provide an understandable explanation of what a domain result indicates. That can be useful for users who need a quicker starting point before examining technical details, as well as for teams that need to share findings with colleagues who do not work with DNS records every day.

The product does not replace the need to assess the source records in context. A DNS result may be technically present while still requiring further review based on the organization’s mail provider, sending services, security policy, or deployment requirements. DNSai’s summaries can help orient users, while the underlying DNS, WHOIS, blacklist, and email-authentication data remains important for a complete assessment.

This combination can support common tasks such as checking whether a domain has published SPF information, reviewing a DMARC policy, investigating a DKIM-related configuration, or gathering context on a domain during research. It is also applicable to DNS troubleshooting, where a user needs both the records themselves and a concise explanation of the findings.

What access methods does DNSai provide?

DNSai is available through the web, API, and MCP. The web product supports interactive research when a person wants to submit a domain and review the returned information. This approach suits one-off investigations, domain ownership checks, and manual DNS or email-security troubleshooting.

API access provides a route for incorporating DNSai capabilities into software and operational workflows. A development or security team may want to request domain data from within an internal application, automate a recurring review process, or attach lookup results to an existing investigation pipeline. DNSai describes API availability, although the scope of programmatic access depends on the selected plan.

MCP connectors provide another access option for AI-oriented workflows. This can be relevant when an agent or assistant needs a tool connection for domain research, email authentication checks, or related security screening. The listed integrations include Claude, Perplexity, Manus, and Grok.

These three delivery methods serve distinct working styles. The web interface is appropriate for direct human use, the API is intended for software integrations, and MCP is intended for compatible AI agent connections. Organizations should select an access path based on whether they need occasional lookups, product integration, or agent-assisted analysis.

What are DNSai’s plans and bulk scanning options?

DNSai offers a free plan as well as Pro, Enterprise, Enterprise Max, and Enterprise Max Premium plans. The free plan costs $0, does not require a credit card, and includes 25 domains and 25 scans per day. This can be suitable for users evaluating the tool or carrying out limited individual domain checks.

The paid plans listed by DNSai are Pro at $30 per month, Enterprise at $99 per month, Enterprise Max at $2,500 per month, and Enterprise Max Premium at $5,000 per month. These tiers indicate that the service is offered to both individual or smaller-scale users and organizations with larger domain-analysis requirements.

Bulk scanning is a stated DNSai feature. This is useful when users need to analyze sets of domains for tasks such as domain research, security screening, or repeated configuration reviews. Bulk and multi-domain workflows can reduce the need to perform each lookup separately, although access to these capabilities is tied to paid plans.

Before selecting a plan, teams should consider whether they need single-domain research, higher-volume scans, multi-domain lookups, or programmatic integration. The free tier can support limited use, while the paid options are more relevant for bulk usage and broader organizational needs.

What are the limitations of DNSai?

DNSai’s free tier has usage boundaries. While it includes 25 domains and 25 scans per day without requiring a credit card, single-domain API access is limited on the free plan. Users who need more consistent automated querying should review the available paid options.

Bulk and multi-domain lookups require a paid plan. This means that teams conducting broader inventories, large-scale screening, or recurring batch analysis will need a subscription that supports those workflows rather than relying on the free tier.

DNSai also states that full programmatic API access is Enterprise-only. Developers planning to make the tool a core part of an application or automated security workflow should verify the relevant Enterprise plan details before implementation. Finally, DNS and WHOIS results reflect the information available from relevant records and data sources, so findings should be considered alongside the user’s own technical, operational, and security context.
