Claude skills for Amazon advertising: use Xnurta's or build your own

What is an Xnurta skill, and how is it different from the connector?

A skill is a written routine the assistant follows for one kind of task: which data to look at, which steps to take, and what the finished answer looks like. The connector is the door. The skill is the SOP taped next to it.

Xnurta MCP connects Claude, ChatGPT and other MCP clients to your Xnurta data. That connection gives the assistant tools it can query. Skills answer a different question. Tools answer "what can the assistant query?" Skills answer "how should it query, analyze and present the result?"

Once a skill is installed, the assistant follows it whenever the scenario comes up. You stop re-explaining the task every Monday. Two people on your team who ask for last week's report get the same structure, not two inventions. What the assistant can reach does not change: that still comes from your own Xnurta login, and writes still need their own permission scope.

How does an SOP become a skill?

You describe the scenario, set the rules and define the output. Those are the three steps the assistant walks you through when you say you want to build a skill, and a decent SOP already contains all three. Most SOPs fail the same way, though. They live in a doc, and the doc lives in a folder, and the folder lives in someone's memory of a folder.

If your SOP is a page of judgment calls, split it. Write the part that is the same every week as a skill and keep the judgment in the chat. A routine that only reads data cannot change your account, because queries never modify it.

How do you build your own skill?

You tell a skills-capable assistant you want to build a skill, then give it the three parts in plain words. It can test-run the skill on your real data and save it once you are satisfied. Treat that test run like a new hire's first report: check the window it pulled, the rules it applied and the shape of the answer, then fix what is off in the chat and run it again.

I want to build a Skill for my Xnurta MCP setup.

Scenario: [when this routine runs and for which ad account, for example every Monday, last 7 days, ad account [account name]].
Rules: [your SOP steps in order, with thresholds, for example flag campaigns with ACOS above [X]% and spend above [Y] with no orders].
Output: [the format you want, for example one table with spend, sales and ACOS, then three suggested actions].

Test-run it on ad account [account name] and show me the result before you save anything. When I am happy, save it as private.

Good first candidates are the routines you already do on a schedule: a Monday review, a pre-Prime Day budget check, a quarterly business review outline. Start with one that only reads. Add a routine that changes campaigns later, once you trust how the assistant handles the first.

Which official Xnurta skills exist for Amazon advertising?

Xnurta ships official skills for reports and diagnosis, AI managed groups and campaign tools. For a routine outside that list, such as a Prime Day check or a quarterly review, you build your own.

The campaign tools also include Promo Adjustment Reset. Ask your assistant to describe it before you run it. The install instructions live in the Xnurta MCP repository on GitHub.

How do you install skills after you connect?

You ask the assistant to install them, in a new chat, after the connector is in. Adding a connector never installs skills, so a connected assistant with no skills is normal, not broken. Connect Claude or ChatGPT to Xnurta MCP covers the connection itself.

Please read this GitHub repository and follow the instructions to install the Xnurta Skills: https://github.com/Xnurta/Xnurta-MCP

I want the weekly ads report.

Name the skill you want and the assistant guides you through installing it. If it connects MCP but skips the skills, send the repository link again. After your CSM turns on write access, remove the connector and add it again (token users create a new token), then ask the assistant to update your Xnurta skills.

Can you keep a skill private or share it with your team?

Yes. After you save a skill, you choose: keep it private, or publish it within your organization so teammates can install it. Your first draft can stay yours until it has survived a few real Mondays.

Sharing a skill shares the routine, not anyone's access. Each person still signs in with their own Xnurta login and sees only the ad accounts and permissions that login carries. An agency lead can write the Monday review once and have the whole team follow it, and Client reporting with MCP: from question to slide shows what that looks like for client reporting.

What stays under your control when a skill runs?

Reading skills change nothing, and writing skills change your account only if write access is on for it. Writing comes in three kinds: managed group management, ad-entity editing and SP campaign creation. Each has its own permission scope, so a scope that edits ads does not necessarily create campaigns.

Four controls stay with you whichever skill is running:

1. Approval. Changes to money, bids or archiving return a preview first, showing which objects change and from which value to which value. Nothing is submitted until you confirm.
2. Irreversible steps. Archiving cannot be undone, and campaigns cannot be deleted, only archived. Pause a campaign if you only want it to stop.
3. History. The operation log holds human and AI actions on campaigns, ad groups, targets, bids, budgets and managed groups. Who changed my Amazon campaign? shows how to ask for it.
4. Override. Ask the assistant to list the objects and exact values before it executes anything, and say no at the preview. Test a new skill on one ad account before you share it.

If you connect with a token instead of the connector, you create it in Xnurta under MCP & Skill and choose its scope there. Read-only vs read-write MCP for Amazon advertisers explains which access to start with.
