Community Gmail server with auto-auth: search, read and send email via MCP.
scan.mx Email Diagnostics is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.
What it does
Email deliverability check: MX, SPF, DKIM, DMARC, blacklists, MTA-STS, DNSSEC, BIMI. Graded, no key.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http scan-mx-email-diagnostics-mcp https://api.scan.mx/mcp
# 2 — ask your agent for something these tools do
# check_domain, check_mx, check_spf and 6 more
scan.mx Email Diagnostics costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http scan-mx-email-diagnostics-mcp https://api.scan.mx/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
9 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Run the full email and DNS deliverability check for a domain: MX, SPF, DKIM, DMARC, DNS health, provider detection, and blacklists. Returns a letter grade (A+ to F, where specific weaknesses cap the grade), a 0 to 100 score, and every individual check with its RFC reference. Set include_smtp to also run a live SMTP probe of the mail servers: the probe is non-blocking, so when smtp_status is "pendi
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The domain to check, e.g. example.com. No scheme or path. |
| include_smtp | boolean | no | Also run a live SMTP connectivity probe of the MX hosts. Non-blocking: poll by re-calling until smtp_status is complete. |
Check the MX records of a domain: presence, hostnames, resolution, null-MX, and common misconfigurations.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The domain to check, e.g. example.com. No scheme or path. |
Check the domain SPF policy: presence, syntax, the all qualifier, and the 10-lookup limit.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The domain to check, e.g. example.com. No scheme or path. |
Check the domain DMARC policy at _dmarc: presence, policy strength (none/quarantine/reject), and reporting.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The domain to check, e.g. example.com. No scheme or path. |
Check whether the domain and its mail server IPs are listed on the Spamhaus (ZEN, DBL, ZRD, AuthBL), SpamCop, GBUdb and PSBL blocklists.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The domain to check, e.g. example.com. No scheme or path. |
Check the domain MTA-STS policy (_mta-sts TXT and the HTTPS policy file, mode and MX coverage) and its TLS-RPT reporting record.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The domain to check, e.g. example.com. No scheme or path. |
Check DNSSEC validation and DNS health: delegation, nameserver count, SOA, and reverse DNS of the mail servers.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The domain to check, e.g. example.com. No scheme or path. |
Check the domain BIMI record at default._bimi: the SVG logo URL, the VMC/CMC certificate, and the DMARC enforcement BIMI needs.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The domain to check, e.g. example.com. No scheme or path. |
Check DKIM signing keys for a domain. Without a selector, common provider selectors are probed. Pass an explicit selector to look up that exact key at selector._domainkey.
| Parameter | Type | Required | Notes |

- Every tool — any call limit is its publisher’s, not ours
- No card, and mcprush charges nothing for it
- Runs at its publisher’s own address — this marketplace is not in the path
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |

Nothing here is billable: mcprush charges nothing to install scan.mx Email Diagnostics or to call it, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.1.0.
No release note was published with this version.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Any signed-in account that does not publish scan.mx Email Diagnostics can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
