Add XM Cloud API Integration

You are helping the user add XM Cloud API integration to their Sitecore Marketplace app.

Prerequisites

The XMC package must be installed. If not:

npx shadcn@latest add https://marketplace-sdk.sitecorecloud.io/r/xmc.json

Step 1: Determine Which API

Ask the user (or infer from $ARGUMENTS) which XMC API they need:

| API | Namespace | Use For |

|-----|-----------|---------|

| Sites | xmc.sites.* | List/get sites, current site context |

| Pages | xmc.pages.* | List/get pages, current page context |

| Authoring | xmc.authoring.* | GraphQL queries/mutations against authoring API |

| Content Transfer | xmc.contentTransfer.* | Import/export content |

| Search | xmc.search.* | Search content items |

| Agent | xmc.agent.* | Invoke XM Cloud agents |

Step 2: Choose Client-Side or Server-Side

Client-side: Use client.query() / client.mutate() — simpler, works in any architecture
Server-side: Use experimental_createXMCClient() — requires Auth0 (full-stack architecture)

Step 3: Implement

See xmc-patterns.md for complete code patterns for each API.

Use /marketplace-build-component to build UI for the data
Use /marketplace-sdk-reference for detailed type information

How to use it

Copy the folder

Take vercel-labs/marketplace-add-xmc from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference npx. Without those the skill loads but fails at the first command.
