Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (16)

`analyze_email_headers`read-only	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.
`check_bimi`read-only	Check a domain's BIMI record (logo in the inbox) and whether its DMARC policy is strict enough for BIMI to show.
`check_blacklists`read-only	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.
`check_cold_email`read-only	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.
`check_dkim`read-only	Look up a domain's DKIM public key, trying the selectors Google Workspace, Microsoft 365 and common senders use, plus one you name.
`check_dmarc`read-only	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DMARC record: whether one exists at _dmarc, its policy (none, quarantine, reject), whether reports are collected, and outdated tags.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.
`check_domain_email_setup`read-only	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.
`check_mta_sts`read-only	Check a domain's MTA-STS policy, which forces encrypted delivery of incoming mail.
`check_mx`read-only	List a domain's mail servers (MX records) and which provider handles its email.
`check_spf`read-only	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.
`generate_dkim_record`read-only	Format a DKIM public key as the TXT record to publish at selector._domainkey.yourdomain.
`generate_dmarc_record`read-only	Build a valid DMARC TXT record (to publish at _dmarc.yourdomain) from a policy and report addresses.
`generate_spf_record`read-only	Build a valid SPF TXT record for a domain from the email services it sends with, with warnings about the 10-lookup limit.
`guess_email_addresses`read-only	List the likely email address formats for a person at a company domain (first@, first.last@, flast@ ...). Guesses only: verify before sending.
`suggest_sending_domains`read-only	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.
`test_subject_line`read-only	Score a cold email subject line out of 10: length, wording that hurts opens, and spam trigger words, with fixes.

Schemas: list_tools.
