"Checking Domain Name Availability" matching MCP servers:

Enables domain overviews for security and sales, providing registration, infrastructure, and risk signal data through a simple API request.

Provides comprehensive email deliverability and domain registration analysis, evaluating SPF, DKIM, DMARC, DNS records, and expiry to identify issues and suggest fixes.

MCP server providing comprehensive domain intelligence (WHOIS, DNS, SSL, domain age) for due diligence and security audits, with pay-per-call via x402 micropayments.

Enables AI agents to run domain-intelligence investigations through six free tools: sanctions screening, IP geolocation with VPN/Tor detection, email validation with breach status, company profiling, WHOIS and email-security scoring, and a single-call domain dossier.

MCP server that lets agents check domain email authentication (SPF, DKIM, DMARC, MX) via a free API, returning grades and shareable report URLs. Also provides tools for listing paid services and partner program terms.

Enables agents to call typed code-review and content-moderation decision tools, returning structured verdicts, probabilities, and confidence-gated actions.

Enables AI agents to audit email and domain security (SPF, DKIM, DMARC, etc.) for any domain without requiring API keys.

Enables auditing any domain's email deliverability and DNS health, including SPF, DKIM, DMARC, MX, mail provider, DNS blacklist status, catch-all, domain age, and a deliverability score.

Enables AI agents to run domain and website intelligence checks, including WHOIS/RDAP, DNS and email security, TLS headers, subdomains, tech stack, contacts, SEO, Core Web Vitals, sitemaps, and Wayback page diffs, using the caller's own Apify token.

Enables email and domain checks, including SPF lookup limits, DKIM keys, DMARC, DNS records, and registration expiry.

Enables AI agents to access only task-relevant data with secrets hidden and personal details pseudonymized, while enforcing destination policies to prevent data leakage even under prompt injection.

Provides email validation and domain configuration auditing tools for AI assistants, enabling single address checks, bulk list cleaning, SPF verification, and full mail setup grading (A-F) with actionable fixes.

Enables checking of package vulnerabilities and supply-chain risks using Attestd API. Supports single and batch checks, CVE details, and covered products listing.

Enables AI agents to access VirusTotal intelligence through MCP, supporting file, URL, domain, and IP lookups, plus analysis, via remote HTTP or local stdio.

Provides verified dependency-audit verdicts for AI agents, checking installed versions against OSV advisories and splitting direct vs transitive dependencies.

Enables MCP-capable agents to gate their actions behind human consent, checking consent rules and requesting approval via Telegram before proceeding with high-stakes operations.

An MCP server that checks SPF, DKIM, DMARC, and MX records for a domain, returning a health verdict and specific DNS fixes to improve email deliverability.

Enables AI shopping agents to verify a storefront's legitimacy before committing payment by checking domain registration, SSL certificate history, HTTPS validity, and known-scam blocklists, returning a trust score with explainable reasons and a clear recommendation.

Enables AI agents to perform passive security scans on domains, checking email spoofing (DMARC/SPF/DKIM), TLS weaknesses, security headers, exposed files, and subdomain-takeover risk without needing an API key.

Verifies npm packages for security risks before installation, checking advisories, install scripts, typosquatting, and other factors, providing safe/block verdicts.
