DigiCert MCP with Claude: Manage Certificates and PKI Through Natural Language
The short answer
Claude works with DigiCert through the Model Context Protocol (MCP), an open standard that lets Claude securely use other software. Once connected with an API key, Claude can check certificate status, issue or revoke credentials and manage PKI workflows when someone asks in plain language. Your team controls what Claude may access and approves consequential actions.
What is Digicert?
DigiCert is a global provider of high-assurance TLS and SSL certificates, public key infrastructure (PKI) and digital signing solutions. Organisations use it to secure websites, applications, internal systems and connected devices, including Internet of Things (IoT) hardware. IT security teams, DevOps engineers, platform owners and compliance staff rely on it to keep digital interactions trusted and encrypted. Because certificates expire and must be renewed on time, the work is routine but important.
How Claude connects to Digicert through MCP
The Model Context Protocol (MCP) is an open standard that works like a universal adapter between Claude and a tool. It lets Claude read information and take actions in software such as DigiCert, using permissions your organisation sets. Instead of logging into a portal and searching through records, your staff can ask a plain question and receive a clear answer.
Once connected, Claude can typically look up whether a certificate is active, expiring or revoked, and help request new certificates or manage existing ones. Requests can be made in natural language, such as asking which certificates expire in the next thirty days. Claude can also help assemble status summaries for security reviews.
Access is limited to what you approve. The connection uses an API key with least-privilege settings, so Claude only reaches the functions your team allows. Consequential actions, such as revoking a credential, can be set to require a named person's approval before they run, and every action is recorded in audit logs for review.
What you can automate
Expiry monitoring and early warnings
Claude can check which certificates are due to expire within a chosen window and produce a prioritised list. Platform teams receive the list each week, so renewals are planned rather than discovered during an outage. The result is fewer surprise expiries that can take websites or internal services offline.
Certificate status checks for support teams
When a customer reports a secure-connection warning, a support agent can ask Claude whether the relevant certificate is valid, revoked or near expiry. Claude gives a plain-English answer and suggests the next step. This shortens investigations and gives frontline staff confidence without needing portal access.
Renewal requests with approval
Developers can ask Claude to prepare a certificate request for a new service, with the details filled in from an internal ticket. A security lead reviews and approves the request before it is submitted. This keeps speed for engineers while preserving the controls that auditors expect.
Revocation response during a security incident
If a private key may have been exposed, a security team can ask Claude to identify every affected certificate and prepare revocation requests. Named approvers confirm each action before it runs. Claude also records the timeline for the incident report, helping responders act quickly and document clearly.
Audit and compliance reporting
Compliance staff can ask Claude for summaries of certificate inventory, issuance activity and expiry risk across business units. Claude assembles the figures into a readable report for internal audit. Teams spend less time exporting data and more time reviewing what it means.
An end-to-end workflow: Certificate renewal with ticket-driven approval
TriggerA certificate expiry alert is raised in the company's ticketing system, such as ServiceNow or Jira, thirty days before a customer-facing service certificate expires.
Claude reads the ticket and identifies the affected domain and certificate.
Claude checks the current certificate status in DigiCert and confirms the expiry date.
Claude prepares a renewal request with the required details drawn from the asset register.
The security lead receives the draft in Microsoft Teams and approves or amends it.
Claude submits the approved request to DigiCert and posts the reference number back to the ticket.
Once issued, Claude records the new expiry date in the asset inventory and closes the ticket after the engineer confirms installation.
OutcomeTypical outcome: renewals are completed well before expiry, with a clear approval trail and no manual copying between systems. Results depend on your current processes and approval rules.
How we set it up
Free automation audit
We review how certificates are currently requested, tracked and renewed, and identify the workflows worth automating first. You receive a short written summary with recommendations at no cost.
Secure connection with an API key
We connect Claude to DigiCert using an API key stored in your secrets manager, with least-privilege permissions. Only the functions your team approves are made available to Claude.
Workflow design across your systems
We design the end-to-end process across DigiCert and your other tools, such as Microsoft 365, ticketing and asset registers. We agree in advance which actions need human approval.
Testing and launch with monitoring
We test the workflow against real past renewals and incidents, then launch with audit logging and monitoring. Any unexpected behaviour is caught during the testing phase, not in production.
Team training and handover
We train your security, DevOps and support staff on how to use Claude safely, including how to approve actions and read the audit logs. We hand over documentation so your team can maintain and extend the workflow.

For teams in the US, UK, India and the Middle East
Organisations in the United States, the United Kingdom, India and the Middle East each have different data protection rules, including the Digital Personal Data Protection Act, 2023 in India and data protection laws in the UAE and Saudi Arabia. We design each deployment around the rules that apply to your organisation. Custom applications can be hosted in India, the United States, the United Kingdom or the European Union, so the region is chosen to meet your requirements.

Frequently asked questions
What does the DigiCert MCP server do?
An MCP server is the bridge that lets Claude use DigiCert securely. It exposes the functions your team permits, such as checking certificate status or preparing requests, in a standard format Claude understands. Where an official server is available we use it; otherwise we use a secure managed connector. Access is controlled by the permissions you set.
Is it secure to connect DigiCert to Claude?
Security depends on design. We use an API key stored in your secrets manager, least-privilege permissions, human approval for consequential actions and full audit logging. Claude only reaches the functions you allow. We also help you rotate keys and review access regularly so the connection stays under your control.
What can Claude do with DigiCert once connected?
Typically Claude can check certificate status and expiry, summarise inventory, prepare issuance or renewal requests and, where you allow it, request revocation. Each action can be limited or require approval. The exact capabilities depend on the API functions and permissions your organisation configures during setup.
How long does setup take?
Timelines vary with the number of workflows and the systems involved. A focused single workflow often moves from audit to launch in a few weeks, while broader programmes take longer. We confirm the timeline after the free automation audit, once we understand your current processes.
Which plan or permissions are needed?
Generally, you need a DigiCert account with an API key whose permissions match the functions you want Claude to use. The specific plan requirements depend on your existing DigiCert agreement. During the audit we check your current access and recommend any changes needed before connecting.
