OpusDNS MCP Server in practice: what can I actually do with it?

This article walks through concrete examples of what you can do with the OpusDNS MCP Server once it is connected. Background on tools and connection setup is linked at the end.

Example 1: Renew a single domain

Task: "Renew example.com for one year."

What happens behind the scenes:

1. search_operations searches for "renew domain" and finds the matching operation
2. describe_operation shows the required parameters, here domain name and term length
3. call_operation runs the operation with the actual values

Since this is a write operation, an approval prompt appears first with the exact details. The domain is only renewed after confirmation.

Example 2: Get an overview of your portfolio

Task: "How many domains do I have and what is expiring soon?"

A single call to portfolio_summary, with no arguments, is enough. It returns overall counts and an outlook on upcoming expirations, a good starting question for a regular check.

Example 3: Filter for domains that are about to expire

Task: "Show me all .com domains expiring in the next 30 days, just name and expiry date."

This is what portfolio_query is for. You filter by TLD and expiry window and ask for only the fields you need. That keeps the answer compact even for portfolios with thousands of domains.

Example 4: Lock many domains against transfer at once

Task: "Lock all .com domains expiring in 30 days against transfer."

This is the classic bulk case, done in two steps:

1. bulk_preview with the selector {"tld": ["com"], "expires_in_30_days": true} shows upfront how many domains would be affected, for example "matchedDomains: 412", without changing anything
2. bulk_submit with the same parameters submits the change. The approval prompt names the exact set, for example "Approve: domain_update_bulk on 412 domain(s) matching expires_in_30_days=true"

Once approved, a batch is created and its progress can be tracked with job_batch_status (queued, running, succeeded, failed). If something needs to pause or stop, job_batch_control handles pausing, resuming, retrying, or canceling, also requiring approval.

The practical benefit: domains are resolved server side through the selector, so there is no manual list to assemble or type out.

Example 5: Working with sub organizations

Task: "Show me the portfolio for customer X" (in reseller setups)

Here, the target organization's organizationId is passed on every call. This matters especially for bulk actions: bulk_preview and bulk_submit need the same organizationId, otherwise the execution affects a different set of domains than the preview. The approval prompt always shows which organization the action applies to.

Example 6: Tackling an unfamiliar task

Task: "Can I lock a domain so it cannot be accidentally deleted?"

If it is not clear which operation covers this, search_operations is the entry point. Results can be checked in more detail with describe_operation before anything runs. This way, the API can be explored without memorizing endpoint names.

Rules of thumb for daily use

• For bulk changes, always use bulk_preview before bulk_submit, never loop individual call_operation calls
• With portfolio_query, only request the fields you actually need
• Read approval prompts carefully, they show the exact set of domains and the exact action
• On reseller accounts, pass organizationId consistently on every call
