MxToolbox MCP with Claude: Faster Email and DNS Troubleshooting for IT Teams
The short answer
Claude works with MxToolbox through the Model Context Protocol, an open standard that gives Claude secure, permissioned access to the tool. Once connected with an API key, Claude can run DNS lookups, check domain blacklists and review email server health, then explain the results in plain English so IT teams can act faster.
What is Mx toolbox?
MxToolbox is a network diagnostic and monitoring service. It offers tools for DNS records, domain blacklist checks, and email server health, helping teams find problems before they affect users. IT administrators, network engineers, email operations staff and managed service providers use it to troubleshoot delivery issues, verify domain settings and keep network services running reliably.
How Claude connects to Mx toolbox through MCP
The Model Context Protocol, or MCP, is an open standard that lets Claude use other software securely. Think of it as a universal adapter between Claude and a tool like MxToolbox. The organisation decides what Claude is allowed to see and do, and access can be limited to only the functions a team needs.
Once connected, Claude can look up DNS records, check whether a domain or IP address appears on a blacklist, and review the health of email servers. A team member can ask a question in ordinary language, such as asking why messages from a domain are landing in spam, and Claude can gather the relevant checks and summarise what it finds.
People stay in charge. Access uses an API key that the organisation issues and can revoke at any time. Consequential actions can be set to require human approval, and activity can be logged so the team can review what was checked and when.
What you can automate
Email delivery investigations
When customers report that messages are not arriving, Claude can review the sending domain's DNS settings and email server health through MxToolbox, then present likely causes in plain language. Support and IT staff spend less time switching between screens and more time fixing the underlying problem.
Blacklist monitoring for sending domains
Marketing and operations teams often rely on a small set of sending domains and IP addresses. Claude can check these against blacklists on a regular schedule and flag any listings, so the team can request delisting before campaigns are affected.
Domain change verification
Before a website or email migration, IT teams need to confirm DNS records are correct. Claude can run the relevant lookups, compare results with the planned configuration and list any mismatches for an engineer to review.
Network incident triage
When a service becomes slow or unreachable, the first hour of diagnosis matters. Claude can run a sequence of network and DNS checks, group the results and suggest where the team should look next, helping on-call engineers reach a starting point faster.
Client reporting for managed service providers
Service providers who look after many client domains can ask Claude to summarise DNS and email health across accounts. This produces clear, readable updates for account managers and clients without manual data gathering.
An end-to-end workflow: Email deliverability alert to resolution
TriggerA helpdesk ticket reports that customer invoices are going to spam, or a scheduled check shows a sending domain has been listed on a blacklist.
Claude runs DNS lookups on the sending domain to confirm SPF, DKIM and DMARC records are present and correctly formed.
Claude checks the sending IP addresses and domain against blacklists and notes any active listings.
Claude reviews the mail server's health results and identifies any configuration warnings.
Claude drafts a plain-language summary and a suggested fix list, and creates a ticket in the organisation's ticketing system with the findings attached.
An IT engineer reviews the summary, approves the changes, and Claude updates the ticket and notifies the account owner in Microsoft 365 once the issue is resolved.
OutcomeTypical outcome: the investigation that once took a team most of a morning can be completed in a fraction of the time, with a clear record of findings and actions for audit purposes.
How we set it up
Free automation audit
We review how your IT and operations teams currently diagnose DNS, blacklist and email issues, and identify the workflows where Claude would save the most time.
Secure connection with an API key
We connect Claude to MxToolbox using an API key issued to your organisation. The key is stored securely and access is limited to the functions your workflow needs.
Workflow design across your systems
We design the end-to-end process across MxToolbox and your other tools, such as Microsoft 365, your ticketing system or CRM, with human approval points for consequential actions.
Testing against real cases
We test the workflow using past support tickets and incidents to confirm Claude's findings match what your engineers would expect, and adjust the process where needed.
Launch, monitoring and training
We launch with audit logging and monitoring in place, then train your team on how to use Claude with MxToolbox and how to review its outputs.
Who benefits
- IT Operations Manager
- Faster triage of network and email incidents, with consistent, documented diagnostic steps.
- Email Administrator
- Quicker identification of DNS and blacklist problems affecting message delivery.
- Managed Service Provider Account Lead
- Readable health summaries across client domains without manual data gathering.
- Helpdesk Team Lead
- Clearer tickets with diagnostic findings attached, reducing back-and-forth with engineers.
Security and control
- Access uses an API key that can be rotated or revoked at any time, and is limited to the functions your workflow requires.
- Consequential changes, such as DNS edits or delisting requests, can be set to require approval from a named engineer.
- All Claude activity can be logged, giving your team a record of what was checked, when and by whom.
- Claude's findings are presented as suggestions for review, not as final decisions, and should be verified before changes are made to live systems.
For teams in the US, UK, India and the Middle East
Organisations in the United States and the United Kingdom can host the workflow in those regions to align with their data protection and governance requirements. Companies in India must consider the Digital Personal Data Protection Act, 2023, and we can host in India to support that. Organisations in the UAE and Saudi Arabia must meet local data protection laws, and we can choose a hosting region that suits those rules. The hosting region is selected during design to meet your specific requirements.

Frequently asked questions
What does the MxToolbox MCP server do?
The MxToolbox MCP server lets Claude carry out MxToolbox checks, such as DNS lookups, blacklist checks and email server health reviews, through a standard connection. Claude sends requests to the tool and receives results, which it then explains in plain language. The server acts as a secure bridge, so Claude only reaches the functions the organisation has allowed.
Is connecting MxToolbox to Claude secure?
Security depends on how the connection is set up. We use an API key issued to your organisation, store it securely, and limit access to the functions your workflow needs. Activity can be logged and reviewed, and keys can be revoked at any time. Consequential actions can require human approval before anything changes.
What can Claude do with MxToolbox once connected?
Typically, Claude can run DNS lookups, check domains and IP addresses against blacklists, review email server health, and summarise the results. You can ask questions in everyday language, and Claude can combine several checks into one report. It does not change your live systems unless you have explicitly set up that action with approval.
How long does setup take?
Timelines vary with the number of domains, the systems involved and how many approval points you need. A focused deployment for a single workflow is often completed in a few weeks, including testing and team training. We confirm a realistic timeline during the free automation audit.
Which plan or permissions do I need?
You need an MxToolbox account with API access, and an API key issued for your organisation. The level of access and any plan requirements depend on the features your workflow uses. We check these during the audit so your team knows what to arrange before setup begins.
