What this server can do

1 function, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

email_audit_deliverability(domain)
Use this when you need to audit email deliverability configuration for a domain. Returns structured JSON with authentication record analysis and a deliverability score 0-100. POST variant of email_audit_deliverability -- same params passed as JSON body instead of query string. 1. score (number 0-100) -- overall deliverability health score 2. spf (object) -- SPF record found, valid syntax, includes count, too-many-lookups flag 3. dkim (object) -- DKIM selectors tested (google, default, selector1, selector2), which ones pass 4. dmarc (object) -- DMARC record found, policy (none/quarantine/reject), rua/ruf reporting addresses 5. mx (object) -- MX records found, priorities, mail server hostnames 6. recommendations (array) -- prioritized list of fixes to improve inbox placement Example output: {"score":65,"spf":{"found":true,"valid":true,"record":"v=spf1 include:_spf.google.com ~all"},"dkim":{"google":true,"default":false},"dmarc":{"found":true,"policy":"none","record":"v=DMARC1; p=none"},"mx":[{"priority":10,"exchange":"alt1.gmail-smtp-in.l.google.com"}],"recommendations":["Upgrade DMARC policy from none to quarantine","Add DKIM for default selector"]} Use this BEFORE launching email campaigns, onboarding new domains for outreach, or diagnosing inbox placement issues. Essential for email marketers, sales teams, and IT admins managing domain reputation. Do NOT use for single email validation -- use email_verify_address instead. Do NOT use for finding email addresses -- use email_find_by_name instead. Do NOT use for domain WHOIS/DNS -- use domain_lookup_intelligence instead. Required: domain.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.

These share tags the maintainers applied themselves, such as monitoring, security, x402. Common tags like "mcp" or "ai" are ignored for this: agreeing with six hundred other projects is not a similarity.

This is not a recommendation and not a test result. It is a map of what the authors said their work is about.
