Mx toolbox MCP integration
Runs blacklist checks, reads SPF, DKIM, DMARC, and BIMI records, and tests SMTP, DNS, and HTTP reachability on demand.
13actions available
Three actions you can hand over today
Every action runs live through MCP. Nothing to build, nothing to maintain.
Lookup dmarc record
Lyro retrieves and validates DMARC email authentication records for a domain. IT teams ensure email deliverability and prevent phishing before security breaches occur.
Lookup blacklist
Lyro performs a blacklist check on a domain or IP address against known spam databases. Email admins identify and remove blocked senders before they damage reputation.
Monitor status
Lyro checks the current status of all configured monitoring jobs in MxToolbox. Ops teams get a complete health snapshot of email infrastructure without manual status pages.
How businesses use Mx toolbox + Lyro
Each card is one request a support team gets, and the Mx toolbox actions Lyro runs to close it.
Find out why a domain's mail is being rejected
Lyro runs a blacklist check on the domain or sending IP, reads the MX records behind it, and tests the SMTP connection, so a bounced-mail report comes back with a named listing rather than a guess.
Lookup BlacklistLookup MX RecordsSMTP LookupVerify SPF, DKIM, and DMARC in one pass
Lyro pulls each authentication record for the domain and reports which checks pass and which fail, so a misaligned DMARC policy is caught before it quietly quarantines a campaign.
Lookup SPF RecordLookup DKIM RecordLookup DMARC RecordCheck BIMI and MTA-STS before a send
Lyro confirms the BIMI record resolves and the DMARC policy is strict enough to qualify for it, and validates the MTA-STS policy alongside the domain's DNS health.
Lookup BIMI RecordLookup MTA-STS RecordLookup DNS RecordsReport on live monitors and host reachability
Lyro reads the health, last check time, and failing tests of every monitor in the account, and runs a ping or HTTP test against the host in question, so an is-it-down question is answered from a check made just now.

How it works
Get started in 3 steps
Connect once, then just ask. There is no workflow builder to learn and nothing to maintain — Lyro reads the Mx toolbox actions it has and picks the ones a request needs.
- 01
Connect Mx toolbox
Authorize the Mx toolbox account your team already uses — one consent screen, no API keys, no mapping tables. Lyro can only do what you granted that account, and you can disconnect it at any time.
- 02
Tell your agent what you need
Describe the job the way you would hand it to a teammate. Lyro maps it to the Mx toolbox actions that close it and chains as many as the request needs.
- 03
Watch it work
The agent runs the actions inside the conversation the customer is already in, so nobody copies data between tabs and your team can take over at any point.

Everything else about Mx toolbox
Setup, permissions, and the limits of what Lyro can do inside Mx toolbox.
No. Every action in the connected toolkit is diagnostic: Monitor Status reads the health of monitors that already exist, and the remaining twelve are lookups and connectivity tests. Setting up or editing a monitor stays in MxToolbox, and Lyro reports on what is configured there.
