Daily SPF, DKIM, DMARC and MX monitoring with webhook alerts, plus free sending-domain audits.
Remote MCP server for email deliverability: audits SPF, DKIM, DMARC, MX and TLS for sending domains, monitors changes, and checks addresses.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.MohDev212%2Fverifypulse/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Public Model Context Protocol (MCP) server card and client interface for VerifyPulse (https://verifypulse-seven.vercel.app), which checks whether email will arrive: daily sending-domain monitoring, on-demand DNS audits and domain-level address checks, paid in USDC on Base over x402.
Address checks are domain-level. VerifyPulse does not offer mailbox verification and cannot confirm that a specific inbox exists. GET /v1/x402/verify-email runs no SMTP probe and reports smtp_check: not_performed. The MCP verify_email tool may attempt one, but the hosting platform commonly filters outbound port 25, so a mailbox result cannot be promised.

Sending-domain audits are free for up to 3 domains per call, with no key:
Source: README.md at commit 8eacb8e
Free. Audit one sending domain: MX hosts, SPF with every include expanded and the true DNS lookup count against the limit of 10, DMARC policy including inheritance from the parent domain, and published DKIM keys. Returns a grade and the fixes to make.
domainrequiredFree for up to 3 domains per call. Audit several sending domains at once and get a grade, SPF lookup count, DMARC policy, DKIM status, MTA-STS (policy checked against the MX hosts), TLS-RPT, BIMI and fixes for each, plus a snapshot to pass to monitor_sending_domains later.
domainsrequiredFree for up to 3 domains per call. Report what changed in SPF, DKIM, DMARC, MX, MTA-STS, TLS-RPT and BIMI since a previous run. Pass the `snapshots` object returned by the previous call as `previous`; the server stores nothing. The first call returns a baseline with no changes.
domainsrequiredpreviousHosted monitoring. Register domains for a daily server-side check of SPF, DKIM, DMARC, MX, MTA-STS, TLS-RPT and BIMI; when something changes, the changes are POSTed as JSON to your https webhook_url. Free for up to 3 domains (renew every 30 days). For 4 to 20 domains in one watch, call without a pass: the result is an x402 payment request for the pass that covers them ($5 for up to 50 domains), payable in params._meta["x402/payment"] or with api_key credits; the paid call returns the pass and starts the watch. Returns a token to list or delete the watch.
api_keydomainsrequiredguard_passwebhook_urlrequiredFree. Replace the includes in a domain's SPF record with the IP ranges they resolve to, and return the TXT records to publish. Use it when an SPF record is at or over the 10-lookup limit.
domainrequiredFix a domain whose email goes to spam or fails SPF, DKIM or DMARC. Returns the exact DNS records to publish (host, type, value) for its mail provider, built from live DNS, in order, with the reason for each. Called without payment it returns a free preview of the fixes plus an x402 payment request for $0.25 USDC on Base (or 250 credits with api_key); a domain that needs no new records gets its advice free.
domainrequiredapi_keyCheck an email address: syntax, whether its domain accepts mail, typo suggestion, disposable and shared-mailbox flags. Checks the domain, not the individual inbox. Costs one credit with an API key (POST /v1/agent/provision returns a key with 100 free credits), or $0.01 USDC on Base per call over x402.
emailrequiredapi_keyFree. Registration data for one domain from the registry (RDAP): when it was registered and its age in days, expiry, registrar, status codes, nameservers and DNSSEC. Flags domains registered in the last 30 days, a strong spam and fraud signal, and domains about to expire.
domainrequiredFree. The TLS certificate a host serves on port 443: whether it validates, issuer, names covered, expiry and days left.
hostrequiredFree. Whether an IPv4 address, or a domain's MX and A addresses, are listed on the SpamCop and PSBL blocklists. Spamhaus and Barracuda are not queried (their terms require a subscription); the result says which lists were checked.
targetrequiredFree. Explain why an email passed or failed authentication or went to spam. Pass the raw message, or just its headers: checks DKIM signatures (verified when the body is included), whether the sending IP is authorized by SPF, DMARC alignment and policy, what the receiving server recorded, and delays at each relay hop. Returns the reasons in plain words.
rawrequiredList the paid HTTP endpoints, their prices in USDC on Base, and the free endpoints.
Takes no parameters.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
