check_domain_email_setupCheck 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 em
check_dmarcCheck 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DMARC record: whether one exists at _dmarc, its policy (none, quarantine, reject), whether reports are collected, and outdated tags.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. Returns pass, warn or fail, the record as published, what was found, ho
check_spfCheck a domain's SPF record: whether it exists, is valid, stays under the 10 DNS lookup limit, and ends with a sensible all mechanism. Use when mail fails SPF or before adding a new sending service. Returns pass, warn or fail, the record as published, what was found, how to fix i
check_dkimLook up a domain's DKIM public key, trying the selectors Google Workspace, Microsoft 365 and common senders use, plus one you name. Use when mail fails DKIM or to confirm signing is set up. Returns pass, warn or fail, the record as published, what was found, how to fix it, and a
check_mxList a domain's mail servers (MX records) and which provider handles its email (Google Workspace, Microsoft 365 and others). Use to find who hosts a domain's email or why it cannot receive mail. Returns pass, warn or fail, the record as published, what was found, how to fix it, a
check_bimiCheck a domain's BIMI record (logo in the inbox) and whether its DMARC policy is strict enough for BIMI to show. Returns pass, warn or fail, the record as published, what was found, how to fix it, and a guide link.
check_mta_stsCheck a domain's MTA-STS policy, which forces encrypted delivery of incoming mail: whether the _mta-sts record exists and the policy file loads, and its mode (testing, enforce or none). Returns pass, warn or fail, the record as published, what was found, how to fix it, and a guid
check_blacklistsCheck whether a domain's sending IPs, or a single IPv4 address, are listed on the major email blacklists (Spamhaus, Barracuda, SpamCop and others). Returns each IP with its result on every list (clean, listed or unknown), totals, and the removal page for each listing.
analyze_email_headersRead 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.
check_cold_emailScore 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.
test_subject_lineScore a cold email subject line out of 10: length, wording that hurts opens, and spam trigger words. Returns the score, a verdict, word and character counts, and each problem with why it matters and how to fix it.
suggest_sending_domainsSuggest 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. Returns the names free to register and the ones already taken.
guess_email_addressesList the likely email address formats for a person at a company domain (first@, first.last@, flast@ ...). Guesses only: verify before sending.
generate_spf_recordBuild a valid SPF TXT record for a domain from the email services it sends with. Returns the DNS host and the TXT value to publish, plus warnings such as nearing the 10-lookup limit. It does not change DNS.
generate_dmarc_recordBuild a valid DMARC TXT record (to publish at _dmarc.yourdomain) from a policy and report addresses.
generate_dkim_recordFormat a DKIM public key as the TXT record to publish at selector._domainkey.yourdomain. Returns the DNS host and the TXT value to paste, plus any warnings. It does not change DNS.
account_summaryOverview of this Pipefire account: campaigns running, emails sent and replies this month, interested leads, and replies waiting for an answer. Start here.
list_campaignsEvery campaign on this Pipefire account with its status, market, people contacted, replies, interested leads, meetings and next send. Use the id with pause_campaign or resume_campaign.
list_repliesProspect replies that need an answer, oldest first: who, which campaign, what the reply was classified as, a snippet, and whether a draft answer is ready. Use the id with get_conversation.
get_conversationThe full email thread with one prospect: what was sent, what they replied, and the draft answer if one is waiting. Sending the answer is done in the Pipefire console (link included), never from here.
resultsEmails sent, replies, interested leads and meetings booked between two dates (inclusive). Dates are YYYY-MM-DD. Defaults to the last 30 days.
pause_campaignStop a running campaign. Nothing further sends until it is resumed. Replies still arrive. Reversible with resume_campaign.
resume_campaignRestart a campaign you paused. A campaign Pipefire paused to protect your sending reputation cannot be resumed from here; the answer says why.
fleet_statusThe sending domains and mailboxes on this Pipefire account: which are ready, which are warming (and on what day), how many emails a day they can send, and anything paused or broken. Pipefire buys, sets up and warms these for you.
get_campaignOne campaign in full: its market, how far it has got (found, verified, contacted, replied, interested), the emails it sends (both subject-line versions of email 1), and a sample of the businesses it will email. Use after create_campaign to read what was written.
create_campaignWrite a new campaign from a short brief: who to email, where, and what you offer them. Pipefire writes the email sequence (two subject-line versions), starts finding and verifying the businesses, and saves it as a DRAFT. Nothing sends until you launch it. Read it with get_campaig
get_launch_linkCheck that a draft campaign has its emails and return the link to it in the Pipefire console, where the user reads the emails and presses Launch themselves. This tool changes nothing and sends nothing.
redraft_replyAsk Pipefire to rewrite the draft answer to a prospect, with an instruction such as "shorter", "more casual" or "offer to send the list first". Returns the new draft. It does not send: get the approval link with get_reply_approval_link.
get_reply_approval_linkCheck that a draft answer is waiting on a conversation and return the link to it in the Pipefire console, where the user reads it and presses Approve to send it themselves. This tool changes nothing and sends nothing.
request_lead_listWhen a prospect replies yes to a lead list, queue it: local businesses of the types they sell to, around their town, verified, as a spreadsheet and PDF on a private link. Ready in about 30 minutes; the link appears in the conversation and get_conversation. Up to 5 a day.
lead_sourcingHow far Pipefire has got finding the businesses for one campaign: how many found, how many with an email, how many emails checked, how many owners named, which sources they came from, and the latest businesses found. Use after create_campaign, or when asked how a campaign's list

Sixteen free email deliverability tools for your AI agent and your terminal. Check a domain's SPF, DKIM, DMARC, MX, BIMI and MTA-STS records, look it up on spam blacklists, read raw email headers, score a cold email and its subject line, and build SPF, DMARC and DKIM records.
Built by Pipefire, cold email software for agencies that sets up and runs outreach for you. The SPF, DMARC and MX checks use the same code Pipefire uses to check its own sending domains, and the cold email checker scores against the same writing rules.
No account. No API key. Nothing you check is stored.
It runs as a remote MCP server (streamable HTTP):
https://pipefire.ai/mcp
claude mcp add --transport http pipefire https://pipefire.ai/mcpgemini extensions install https://github.com/mikelovatt/pipefire-cliThen ask in plain words, for example "Is example.com set up to send email?" or "Score this cold email before I send it".
Pipefire customers: connect the same address in Claude, ChatGPT or Manus and sign in when asked. Your assistant can then read your campaigns, replies, mailboxes and results, draft a new campaign, rewrite a reply draft and pause or resume sending. It never sends an email or launches a campaign: those stay in the Pipefire console behind your click.
Every tool is read-only. Each one also has a free web version on pipefire.ai.

DMARC check for example.com
DMARC (policy and reports): WARN Record: v=DMARC1;p=reject;sp=reject;adkim=s;aspf=s Found: Policy p=reject, with no reports address. Fix: Add rua=mailto:you@yourdomain so you receive the daily reports that show who sends as you.
Every tool calls the same code as the free tools at pipefire.ai/tools, through Pipefire's public MCP endpoint. Checks are rate limited per IP. Nothing you check is stored.
Pipefire is cold email software for agencies that sets up and runs outreach for you. It buys the sending domains, sets up the mailboxes and warms them for 14 days before any cold email goes out. It finds prospects, writes the emails, sends them at a safe daily pace and sorts the replies. You approve every email before it is sent, and your company domain never sends cold email.
