✓ Watched since 2026-06-03 — behavioral baseline locked. We re-check this server's tool surface on a schedule; if it adds, removes, or silently rewrites a tool (rug-pull), we record it.

What it offers — 16 tools · Developer Tools

spf_check

Check if a domain has a valid SPF (Sender Policy Framework) DNS record. SPF specifies which mail servers are authorized to send email on behalf of a d

dkim_check

Check if a domain has a valid DKIM (DomainKeys Identified Mail) DNS record for a given selector. DKIM allows the receiver to verify that an email was

dmarc_check

Check if a domain has a valid DMARC (Domain-based Message Authentication, Reporting & Conformance) DNS record. DMARC tells receiving servers what to d

bimi_check

Check if a domain has a valid BIMI (Brand Indicators for Message Identification) DNS record. BIMI allows brands to display their logo next to authenti

dmarc_generate

Generate a DMARC DNS record for a domain. Returns the record name, value, and type ready to be added to DNS.

spf_generate

Generate an SPF DNS record for a domain based on the email provider being used. Returns the record name, value, and type ready to be added to DNS.

smtp_check

Test an SMTP server connection by attempting to connect and authenticate. If from_email and to_email are provided, the tool may attempt to send a test

imap_check

Test an IMAP server connection by attempting to connect and authenticate. Use this to verify email receiving configuration.

smtp_finder

Look up SMTP server settings (host, port, encryption) for a given email provider. Use this to find the correct SMTP configuration for services like Gm

imap_finder

Look up IMAP server settings (host, port, encryption) for a given email provider. Use this to find the correct IMAP configuration for services like Gm

blacklist_check

Check if a domain or IP address is listed in popular email blacklists (DNSBLs). Being blacklisted can severely impact email deliverability.

mx_lookup

Look up MX (Mail Exchanger) records for a domain. Returns the mail servers and their priorities.

txt_lookup

Look up all TXT records for a domain. TXT records contain SPF policies, domain verification tokens, DKIM keys, and other metadata.

cname_lookup

Look up CNAME (Canonical Name) records for a domain. Shows where a hostname aliases to.

ptr_lookup

Reverse DNS lookup. Find the hostname associated with an IP address. A valid PTR record is important for email sending reputation.

dns_lookup

Look up all DNS records for a domain in one query. Returns A, AAAA, CNAME, MX, NS, TXT, and SOA records.

Observed behavior

No proxied traffic observed for this host yet. Connect it at /connect and its grade gains a measured Reliability score + per-tool behavioral evidence — the half a static scan can't produce.

Findings

No blocking issues found in the static + spec checks.
Grade another server

We re-grade themailx.com on a schedule and alert your Slack/webhook the moment its tools change or its grade drops — rug-pull insurance for the connection.

Agents: check this before connecting

Add the wmcp.sh trust oracle as an MCP server and call grade_mcp_server / check_mcp_drift in your agent's pre-connection gate:

How this grade is computed. An open, independent rubric — Spec conformance (20%), Security mapped to the OWASP MCP Top 10 (30%), Reliability (20%), Tool hygiene (15%), Transparency (15%) — run by connecting to the server and inspecting its real MCP surface. The grade is free and identical whether or not the operator pays. v1 uses static + spec signals from a single connection; continuous uptime, real latency, and annotation-truthing (declared readOnly vs observed behavior) layer on via the wmcp.sh proxy.
