The @deliveriq/mcp server provides 12 tools for email deliverability verification and domain intelligence via the DeliverIQ API.
Verification Tools:
Verify a single email: Check deliverability with reachability status, 0–100 score, syntax/MX/SMTP/disposable/role-based checks, and optional HIBP breach detection
Submit batch verification: Asynchronously verify up to 10,000 emails with optional webhook callbacks
Check batch job status: Poll progress of a running batch verification job
Download batch results: Retrieve completed results as CSV, with optional filtering by category (safe/risky/invalid/unknown)
List verification jobs: Browse and filter past batch jobs with pagination
Intelligence Tools:
Find business email: Discover a person's work email by name and company domain using pattern generation and SMTP probing
DNSBL blacklist check: Check a domain's IP against 50 DNS-based blackhole list zones
Email infrastructure check: Analyze SPF, DKIM, DMARC, MTA-STS, BIMI, and TLS-RPT records with an infrastructure score
Spam trap analysis: Evaluate an email address for spam trap risk using 13 signals (domain age, entropy, disposability, etc.)
Domain intelligence: Get a full domain trust report covering MX records, DNSBL status, infrastructure, domain age, and ISP profile
Organization intelligence: Query email patterns, verified contact counts, and company info for a domain (free)
Account Tool:
Check credits: View remaining credit balance, plan tier, billing period, and usage breakdown by category (free)
Official MCP (Model Context Protocol) server for the DeliverIQ email verification API by MiN8T. Provides 12 tools for AI agents in Claude Desktop, Claude Code, Cursor, and any other MCP-compatible client.
No separate install step needed — npx -y @deliveriq/mcp will fetch and run
the server on demand.
Add to ~/Library/Application Support/Claude/claude_desktop_config.json

Email deliverability is one of those problems where the right answer needs 6–8 API calls (verify → reputation → DMARC → blocklist → infrastructure → ...). Letting Claude orchestrate these as tools is ~10× more useful than shipping another dashboard — the model can plan, branch on results, and explain the verdict in plain English.
