What it can do
Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
inspect_domain_dnsFree. 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.
audit_sending_domainsFree 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.
monitor_sending_domainsFree 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.
watch_sending_domainsHosted 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
flatten_spfFree. 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.
get_fix_kitFix 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 x4
verify_emailCheck 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 Ba
domain_intelFree. 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.
check_tls_certificateFree. The TLS certificate a host serves on port 443: whether it validates, issuer, names covered, expiry and days left.
check_blocklistsFree. 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.
analyze_email_authenticationFree. 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 r
get_x402_payment_endpointsList the paid HTTP endpoints, their prices in USDC on Base, and the free endpoints.

Common questions
Is VerifyPulse: email deliverability checks safe?
It passed 4 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed 11 days ago, and the latest version (2.1.1) reached the registry 11 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

VerifyPulse MCP Server & Agent Client
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.
What VerifyPulse does
- Sending-domain audits: MX, SPF with every include expanded and the true lookup count, DMARC policy and DKIM keys
- Daily monitoring: signed webhook alerts when a domain's SPF, DKIM, DMARC, MX or MTA-STS changes
- Bulk-sender checks: a domain's DNS against the Gmail and Yahoo SPF, DKIM and DMARC requirements
- Domain age and TLS checks: RDAP registration data and certificate status
- Address checks: RFC 5322 syntax, the domain's MX records, typos, and disposable and shared-mailbox flags
What it does not do
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.
