Was dieses MCP kann

Analyzes email authentication, DNS records, delivery headers, blacklist status, and spam-related copy risks.

analyze_headers
Email header analyzer
Parse raw email headers: the Received delivery path with per-hop delays, the receiving server's SPF/DKIM/DMARC verdicts, DMARC alignment of the From domain, DKIM signatures, the sending IP, and bulk-sender requirements such as one-click unsubscribe.

{'type': 'object', 'required': ['headers'], 'properties': {'headers': {'type': 'string', 'description': 'The raw header block (everything above the message body).'}}, 'additionalProperties': False}
check_blacklists
DNS blacklist lookup
Check an IPv4 address against about 18 IP blacklists (SpamCop, Barracuda, UCEPROTECT, PSBL, Mailspike, ...) or a domain against domain blacklists. Each list is verified with its test entries first, so lists that refuse public resolvers (such as Spamhaus) are reported as unavailable rather than clean.

{'type': 'object', 'required': ['target'], 'properties': {'target': {'type': 'string', 'description': 'IPv4 address or domain.'}}, 'additionalProperties': False}
check_domain
Email domain health check
Run every email-authentication check on a domain (SPF, DKIM, DMARC, MX, MTA-STS, TLS-RPT, BIMI, plus domain and mail-server blacklists) and return a score out of 100, per-check findings and a prioritized fix list. Use this first when asked whether a domain is set up correctly to send email.

{'type': 'object', 'required': ['domain'], 'properties': {'domain': {'type': 'string', 'description': 'Domain name, e.g. example.com. URLs and email addresses are accepted; the domain part is used.'}, 'dkim_selector': {'type': 'string', 'description': 'DKIM selector (the s= value from a DKIM-Signature header). Optional; common selectors are tried when omitted.'}}, 'additionalProperties': False}
check_record
Check one DNS email record
Look up and validate a single email DNS record for a domain, explaining each tag. record is one of spf, dmarc, dkim, bimi, mta-sts, tls-rpt, mx. SPF counts the 10-lookup limit; DMARC checks policy, reporting and external report authorization; DKIM sizes the key; MTA-STS fetches the policy file and compares it with the MX hosts; BIMI checks the logo (SVG Tiny PS) and mark certificate.

Optional.'}}, 'additionalProperties': False}
check_spam_words
Email copy spam check
Scan an email subject and body (plain text or HTML) for spam-trigger phrases by category, ALL-CAPS, exclamation runs, emoji, URL shorteners and image-heavy HTML. Returns a low/medium/high risk reading and, optionally, a rule-based rewrite.
