Intent: Compare app and plugin approaches, document data boundaries, and test booking paths.
For: business-owner, operator

## Requirements and responsibilities

- Have named ownership of the domain, selected xCloud team and site, and WordPress administrator access. For this scenario, agree who supplies the data and signs off: A clinic's public WordPress pages should direct visitors to an independently run appointment service. Sources: [xCloud agent capability boundaries](https://github.com/xCloudDev/xcloud-agent-skills/blob/main/plugins/xcloud/reference/capability-map.md); [WordPress roles and capabilities](https://wordpress.org/documentation/article/roles-and-capabilities/)
- Use a compatible Nginx or OpenLiteSpeed stack for native WordPress. Verify current server resources, plan eligibility and each selected plugin or service license and requirements before installing; a Docker server does not host a new native WordPress site. Sources: [xCloud agent capability boundaries](https://github.com/xCloudDev/xcloud-agent-skills/blob/main/plugins/xcloud/reference/capability-map.md); [WordPress plugin administration](https://wordpress.org/documentation/article/manage-plugins/)
- Prepare a safe test identity and a completed, accessible backup before consequential changes. The important failure to plan around is: WordPress hosting cannot configure external availability or reminder rules.

## Illustrative situation

Illustrative scenario, not a customer case study: A clinic's public WordPress pages should direct visitors to an independently run appointment service. A visitor books once and staff see the same appointment in the service.

## Choose the approach

- Choose a plain link unless an embed or shared login is explicitly supported and tested. Verify the selected provider or plugin documentation and license against this requirement; xCloud hosting does not supply its business configuration.

- Keep application setup, domain/DNS ownership, mail delivery and external integrations with their named administrators. Use a plain documented path when a proposed integration cannot be demonstrated end to end.

## Dashboard and application procedure

### 1. Define booking data ownership

**Where:** WordPress or selected plugin/app administrator

**Permissions:** Named WordPress or app administrator; business owner signs results.

**Inputs:** Owner, hostname, approved requirements, sample record and decision date. Define booking data ownership.

**Action:** Specify what WordPress publishes and what the scheduler stores: service, staff, availability, customer contact and cancellation data. Decide whether a plain link meets the need.

**Expected result:** Website and scheduler responsibilities are clear.

**Verify:** The owner names the system of record for one appointment.

**If it fails:** If both systems would edit availability, choose one source before launch.

Capability: Configure WordPress content, users and selected plugins
Sources: [WordPress roles and capabilities](https://wordpress.org/documentation/article/roles-and-capabilities/); [WordPress plugin administration](https://wordpress.org/documentation/article/manage-plugins/)

### 2. Provision separate services

**Where:** xCloud Add site and site overview

**Permissions:** Named xCloud team/site administrator; verify the exact target.

**Inputs:** Target team/site, server or plugin version, license and documented prerequisites. Provision separate services.

**Action:** Create native WordPress on a compatible server and choose a separately documented scheduler deployment. Confirm the scheduler's server, template and administrator requirements.

**Expected result:** Both applications have approved addresses and owners.

**Verify:** Open both URLs and record where booking data lives.

**If it fails:** If the scheduler is unavailable for this stack, choose a supported dashboard option or revise the design.

Capability: Create a WordPress site

### 3. Configure availability in the app

**Where:** Easy!Appointments administrator

**Permissions:** Named WordPress or app administrator; business owner signs results.

**Inputs:** Approved change scope, backup state, selected version and maintenance window. Configure availability in the app.

**Action:** In scheduler administration set services, providers, hours, closures and message rules using its vendor guide. Add a clear booking link and support route in WordPress.

**Expected result:** Visitors can discover a usable scheduler.

**Verify:** Compare link target and one service-provider combination with the approved plan.

**If it fails:** If an embed or shared login fails across browsers, retain the plain link.

Capability: Configure the booking application and run acceptance tests
Sources: [Easy!Appointments official initial configuration](https://easyappointments.org/documentation/initial-configuration/); [Easy!Appointments official application settings](https://easyappointments.org/documentation/application-settings/)

### 4. Test customer and staff states

**Where:** WordPress public pages and relevant external provider

**Permissions:** Named WordPress or app administrator; business owner signs results.

**Inputs:** Test accounts, sample content or transaction, expected result and provider access. Test customer and staff states.

**Action:** As a test customer book, cancel and try an occupied slot. Ask staff to find the appointment; check confirmation delivery separately.

**Expected result:** Both sides observe one consistent appointment state.

**Verify:** Match time, service and provider in the customer message and administrator record.

**If it fails:** If staff cannot see a booking or a conflict is allowed, correct app rules before announcing online booking.

Capability: Review a WordPress business journey

### 5. Protect both data stores

**Where:** xCloud Docker Site Backup dashboard

**Permissions:** Named xCloud team/site administrator; verify the exact target.

**Inputs:** Observed results, unresolved failures, backup point and owner contacts. Protect both data stores.

**Action:** Assign update and backup owners for WordPress and the scheduler separately. Include booking records in recovery planning.

**Expected result:** Each service has a named operator and recoverable point.

**Verify:** Inspect both completed backup records and compare timestamps with a newer test booking.

**If it fails:** Never restore older scheduler data over new appointments without an approved reconciliation process.

Capability: Create and inspect Docker backups

## Maintenance

- Assign a cadence for selected WordPress core, theme and plugin updates, review version-based findings and retest the path in this guide. In particular, repeat: A visitor books once and staff see the same appointment in the service. A chat prompt is not a scheduled task. Sources: [Manage WordPress updates with Updates Manager](https://xcloud.host/docs/manage-wordpress-updates-with-updates-manager/); [Vulnerability Checker in xCloud](https://xcloud.host/docs/vulnerability-checker-in-xcloud/)
- Record actual backup completion, storage access and responsible staff. Recheck connected application and provider behavior after changes rather than relying on a site health status alone. Sources: [Site backups in xCloud](https://xcloud.host/docs/site-backups-in-xcloud/); [xCloud agent capability boundaries](https://github.com/xCloudDev/xcloud-agent-skills/blob/main/plugins/xcloud/reference/capability-map.md)

## Recovery decisions

- Keep WordPress content and the separate Easy!Appointments database/storage in distinct backup plans. Before any scheduler restore, compare its point with newer bookings and reconcile them with the app owner; a native WordPress restore does not recreate scheduler records.

## AI handoff

Connect xCloud MCP through the current documented profile and grant only the scopes needed for the selected team. Discover tool schemas first. Read resources to plan; require approval for any supported write. Use returned dashboard URLs for manual work. The packaged REST wrapper accepts GET requests only.

### Supported scope

- **Confirm requirements and inspect resources** (mcp; read): Discover the connected profile and operation schema first; only teams granted to the connection are visible. Checkpoint: Confirm exact team, server and site identity. Use dashboard\_url returned by the resource; do not invent a dashboard link. Operation identifiers to discover: teams.index, servers.show, sites.show. Scopes: read:servers, read:sites. Sources: [xCloud MCP documentation and connection profiles](https://app.xcloud.host/mcp/docs); [xCloud agent capability boundaries](https://github.com/xCloudDev/xcloud-agent-skills/blob/main/plugins/xcloud/reference/capability-map.md)
- **Configure WordPress content, users and selected plugins** (app; manual): Requires a named WordPress administrator or suitable editor. Plugin behavior, commercial license, payment, email and external integration are verified in the chosen vendor documentation and application; xCloud hosting or MCP reads do not configure them. Checkpoint: Open the actual WordPress or selected plugin interface, record the version and role, and have the business owner accept a real user journey. Sources: [WordPress roles and capabilities](https://wordpress.org/documentation/article/roles-and-capabilities/); [WordPress plugin administration](https://wordpress.org/documentation/article/manage-plugins/)
- **Create a WordPress site** (mcp; write): Requires a compatible Nginx or OpenLiteSpeed server; Docker and single-site agentic servers cannot host a new WordPress site. Checkpoint: Approve the exact server, domain, capacity, cost and creation inputs before provisioning. Verify completion and HTTPS. Operation identifiers to discover: servers.sites.wordpress.create. Scopes: write:sites. Sources: [xCloud agent capability boundaries](https://github.com/xCloudDev/xcloud-agent-skills/blob/main/plugins/xcloud/reference/capability-map.md); [xCloud MCP documentation and connection profiles](https://app.xcloud.host/mcp/docs)
- **Configure the booking application and run acceptance tests** (app; manual): xCloud hosting operations do not configure business rules, staff calendars, reminders, payments or WordPress plugins. Checkpoint: An authorized application administrator performs configuration and confirms each customer and staff journey. Sources: [Easy!Appointments hosting, setup and deployment requirements](https://xcloud.host/easy-appointments-hosting/); [Easy!Appointments official initial configuration](https://easyappointments.org/documentation/initial-configuration/); [Easy!Appointments official application settings](https://easyappointments.org/documentation/application-settings/); [Easy!Appointments official appointment notifications](https://easyappointments.org/documentation/appointment-notifications/); [xCloud MCP documentation and connection profiles](https://app.xcloud.host/mcp/docs)
- **Review a WordPress business journey** (app; manual): Application data and observed transactions cannot be inferred from xCloud resource reads. Use authorized test accounts and the application or provider evidence. Checkpoint: Record the test identity, timestamp, expected outcome, observed result and owner decision. Sources: [WordPress roles and capabilities](https://wordpress.org/documentation/article/roles-and-capabilities/)
- **Create and inspect Docker backups** (mcp; write): Backup capture briefly stops the app. Use supported local, S3-compatible or SFTP storage; the packaged REST wrapper is GET-only. Checkpoint: Confirm site, storage, retention and the interruption window before creating a backup or changing settings. Check terminal completion. Operation identifiers to discover: sites.docker.backup, sites.docker.backups, sites.docker.backupSettings.update. Scopes: read:sites, write:sites. Sources: [Docker backup operations and storage constraints](https://github.com/xCloudDev/xcloud-agent-skills/blob/main/plugins/xcloud/skills/sites/reference/docker-backups.md); [Back up and restore Docker apps](https://xcloud.host/docs/backup-and-restore-docker-apps/)

### Copyable agent brief

```text
Help with connect wordpress to an external booking service for the exact xCloud team and site I name. First inspect only resources the connection permits and confirm returned identity, stack and relevant versions. Prepare the following authored workflow: Define booking data ownership; Provision separate services; Configure availability in the app; Test customer and staff states; Protect both data stores. Ask the named dashboard, domain, WordPress and application owners to perform operations outside connected capabilities. WordPress staging push/pull, native backup schedules, restore and cache settings remain manual dashboard tasks; the packaged REST wrapper is GET-only. Use the guide’s checks to report observed application evidence, unresolved questions and recovery implications; do not claim completion from a hosting resource read. Acceptance: Both sides observe one consistent appointment state.
```

### Manual checkpoints

- The named WordPress, app, dashboard or provider administrator performs the guide’s actual configuration step: In scheduler administration set services, providers, hours, closures and message rules using its vendor guide. Add a clear booking link and support route in WordPress.
- The business owner compares the controlled sample with this observable result: Both sides observe one consistent appointment state.
- Staging push/pull, native backup schedules, restores and cache-setting edits require the authorized xCloud dashboard operator; the packaged REST wrapper is GET-only.

## Feature coverage

- **business-acceptance** (covered): A visitor books once and staff see the same appointment in the service. Steps: phase-4
- **recovery** (covered): WordPress hosting cannot configure external availability or reminder rules. Steps: phase-5
