Community Gmail server with auto-auth: search, read and send email via MCP.
Nothing to run from here
Pipefire email deliverability tools 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.

Installation
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.
Claude Codedeclared by this listing
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 pipefire-email-deliverability-tools-mcp https://pipefire.ai/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
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.
What you approve
16 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Check whether a domain is set up to send and receive email properly: MX, SPF, DKIM and DMARC in one go, each with pass/warn/fail, what was found, and how to fix it. Use when someone asks why their email goes to spam, whether their domain is set up right, or before sending cold email.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The domain to check, e.g. example.com. |
| selector | string | no | DKIM selector if known. Common ones are tried automatically. |
Check a domain's DMARC record: whether one exists at _dmarc, its policy (none, quarantine, reject), whether reports are collected, and outdated tags. Tells you whether the domain can be impersonated by email.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The domain to check, e.g. example.com. A URL or email address also works. |
Check a domain's SPF record: whether it exists, is valid, stays under the 10 DNS lookup limit, and ends with a sensible all mechanism.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The domain to check, e.g. example.com. A URL or email address also works. |
Look up a domain's DKIM public key, trying the selectors Google Workspace, Microsoft 365 and common senders use, plus one you name.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The domain to check, e.g. example.com. A URL or email address also works. |
| selector | string | no | DKIM selector if known (e.g. google, selector1). Common ones are tried automatically. |
List a domain's mail servers (MX records) and which provider handles its email.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The domain to check, e.g. example.com. A URL or email address also works. |
Check a domain's BIMI record (logo in the inbox) and whether its DMARC policy is strict enough for BIMI to show.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The domain to check, e.g. example.com. A URL or email address also works. |
Check a domain's MTA-STS policy, which forces encrypted delivery of incoming mail.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain | string | yes | The domain to check, e.g. example.com. A URL or email address also works. |
Check whether a domain's sending IPs, or a single IPv4 address, are listed on the major email blacklists (Spamhaus, Barracuda, SpamCop and others), with removal links.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| target | string | yes | A domain (example.com) or a public IPv4 address. |
Read the raw headers of a received email: SPF, DKIM and DMARC results, alignment, the delivery path and delays. Use when someone pastes headers and asks why a message went to spam or failed authentication.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| headers | string | yes | The raw email headers (the part above the message body). |
Score a cold email (subject and body) out of 10 against the rules Pipefire checks its own emails with: length, reading level, the ask, subject line, and spam-filter wording. Returns each issue with why it matters and how to fix it.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| subject | string | yes | — |
| body | string | yes | — |
| kind | string | no | Which email in the sequence. Default first. |
Score a cold email subject line out of 10: length, wording that hurts opens, and spam trigger words, with fixes.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| subject | string | yes | — |
Suggest lookalike sending domains for cold email (so the main domain is never put at risk), with live .com/.net availability. Give a business name or its website.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| brand | string | yes | Business name (Acme Roofing) or main domain (acmeroofing.com). |
List the likely email address formats for a person at a company domain (first@, first.last@, flast@ ...). Guesses only: verify before sending.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| first | string | yes | — |
| last | string | no | — |
| middle | string | no | — |

ATool-list grade · score 96 / 100
Release 1.0.0 · scanned 21 Oct 2026
Graded from the tools this server lists, not from its source code.
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.

| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | minimal | capability blast radius (minimal) — client exposure if the model is manipulated | −0 |
| coverage-honesty | manifest | inspection depth (manifest) — how much of the target the scan could see | −4 |
score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
