Setup

How Do You Set Up Antigravity to Manage SSL and domains on xCloud?

Connect Antigravity once; every job on this account uses the same connection. Then ask in plain words.

1
Add xCloud in View raw config
In the Antigravity IDE, click the three dots at the top of the agent side panel, choose MCP Servers, then Manage MCP Servers, then View raw config. Paste this into mcp_config.json and save. The field is serverUrl: it is the only remote URL property in Antigravity's documented configuration, so do not write url or httpUrl.
JSON
```
{
  "mcpServers": {
    "xcloud": {
      "serverUrl": "https://app.xcloud.host/mcp"
    }
  }
}
```
2
Sign in, then check the connection
Open Agent settings (Cmd+, on Mac, Ctrl+, on Windows and Linux), go to Customizations and click Authenticate next to xcloud. Approve the teams and the access level in the browser, copy the authorization code it shows, paste it into the settings panel and click Submit. Then ask this in the agent panel.
Prompt
```
Who am I on xCloud?
```
3
No browser sign-in? Use an API key
Create a token with the mcp:invoke scope plus the read abilities for the areas it will use (read:servers and read:sites, with read:billing and read:addons for billing and add-on tools) and the matching write: abilities if it should change things in Settings, Developers, API Tokens and add it as a header. Replace YOUR_TOKEN with the token, which contains a pipe character, and never paste it into chat. Keep this file out of git.
JSON
```
{
  "mcpServers": {
    "xcloud": {
      "serverUrl": "https://app.xcloud.host/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_TOKEN"
      }
    }
  }
}
```

Check it worked

Then ask Antigravity for the job itself, for example:

Prompt

Why does staging.example.com show a certificate warning? Check the certificate and the DNS record and explain what you find.

In practice

How Does SSL and domains Work from Antigravity?

Antigravity puts an agent beside your code, and it can plan more than one step before it reports back. That fits certificate work, which is a short chain of dependent checks: find the site, read its SSL state, test whether the DNS record points at the server, then decide what to install. You open the agent panel and type why does staging.example.com show a certificate warning. The agent resolves the site by its domain, reads the certificate and its expiry, runs a DNS lookup, and writes back a short explanation. It might say the certificate expired two days ago while DNS is fine, or that the record is still pointing at the old host, so a new certificate would fail to issue.

Approval works in two layers here. Antigravity runs MCP tools you have not configured in Ask mode, so it prompts you for each call. xCloud adds its own explicit confirmation for installing, renewing, switching or deleting a certificate, and the agent names the site and the provider before it asks. Reads such as the certificate status and the DNS check are low risk, and Antigravity's permission policy lets you allow those one by one with a pattern like mcp(xcloud/tool_name). A wildcard would also skip the prompt for changes, which is the opposite of what you want for certificates. After you approve, the agent polls the certificate status and loads the HTTPS URL, because a success response only means xCloud accepted the work.

The same mcp_config.json works in the IDE, the command-line tool and the Antigravity 2.0 app, so you can ask the same questions from whichever one you have open. When you want a domain added to a live site, the agent will say that the API cannot do it and give you the dashboard path, Site then Domain, along with the dashboard link xCloud returned for that site.

Antigravity specific: Antigravity's OAuth sign-in ends with a code you paste back: copy the authorization code from the browser tab into Settings, Customizations and submit it, or the certificate tools will stay unauthenticated. Write the entry with serverUrl, because url and httpUrl are not the documented fields. When you allow tools with patterns, name the read tools one at a time, so the install, renew and delete calls keep their Ask-mode prompt.

What xCloud does for ssl and domains

xCloud lets the agent read a site's certificate status, domains and DNS, then install or renew a certificate from xCloud (Let's Encrypt), your own files or a connected Cloudflare account. Adding or changing a domain on an existing site stays in the dashboard, and the agent gives you the path.

Find the site and read its SSL. The agent resolves the site by name or domain, then reads its current SSL state and the list of certificates before it changes anything. That shows the provider, the status and the expiry date.
Check the domain and DNS. It reads the site's primary and additional domains and asks xCloud whether the domain's DNS record points at the server. Each check is one lookup, so the agent repeats it while a record propagates. A record behind Cloudflare's proxy is reported separately.
Choose the certificate source. You pick xCloud's free Let's Encrypt certificate, your own certificate, or the team's Cloudflare integration. If the site already uses a different provider, the agent tells you that switching needs an explicit override and asks first.
Install or renew, once you approve. The agent restates the site and the provider, then installs or renews the certificate. A renewal only runs when the certificate is within seven days of expiry unless you ask for a forced renewal. For a WordPress site turning on HTTPS for the first time, it asks whether to run the database search-and-replace.
Poll to issuance and verify. Install and renew report success before issuance completes. The agent polls the certificate status until it settles, then checks the site over HTTPS before it calls the job done.
Hand off domain changes. If you want to add, change or remove a domain on an existing site, the agent gives you the dashboard path (Site > Domain) and the site's dashboard link, because the API only reads domains after creation.

Reference

SSL and domains Settings and Limits on xCloud

The facts Antigravity works within when it manages SSL and domains. Where a row names the dashboard, that step stays yours to take there.

Setting or limit	What applies
Certificate status	A site's SSL state, its certificate list and one certificate's detail and status are all readable
xCloud certificate	Free Let's Encrypt certificate issued and renewed by xCloud. The domain's DNS should already point at the server before you ask
Custom certificate	You supply the PEM certificate and its private key. The key is a secret and is never returned by a read
Cloudflare certificate	Uses the team's connected Cloudflare account. When the zone is connected, xCloud writes the DNS record and the certificate itself at site creation
Switching provider	Needs an explicit force when another provider is already configured, so the agent asks before it replaces a working certificate
Renewal rule	A renewal does nothing unless the certificate is within seven days of expiry; a forced renewal skips that guard. Renewing needs the site SSL permission on your team role
WordPress first HTTPS	An optional database search-and-replace moves existing http:// URLs to https:// when a WordPress site adopts HTTPS for the first time
DNS check	One lookup per call. A proxied Cloudflare record is flagged, and on a Cloudflare-managed site the proxied record is the finished state, not a fault
Domains (read)	The primary domain, additional domains and the domain update status are readable through the API
Domains (write)	Adding, changing or removing a domain on an existing site is dashboard-only: Site > Domain. A staging site goes live under Site > Domain > Go Live
Deleting a certificate	Available through the API, but it can take a site off HTTPS, so the agent restates the target and waits for your approval
Cloudflare 526 errors	A 526 or a certificate warning is an SSL problem, so the agent reads the certificate first. A 522 is different: it usually means ports 80 and 443 are blocked at the origin

Rules Antigravity has to follow

Installing, renewing, switching or deleting a certificate stops for your approval, and the agent names the site and the provider before it asks.
A success response means xCloud accepted the work, not that the certificate was issued: the agent polls the status and checks the live HTTPS URL.
The agent never replaces a working certificate with a different provider without telling you, and it never turns off the Cloudflare proxy on a site xCloud manages through Cloudflare.
Changing a domain on an existing site is a dashboard step; the agent gives you the path and the dashboard link xCloud returned, not a made-up workaround.
A custom certificate's private key is a secret: it is never returned by a read and should not be pasted into a shared channel.

Example prompts

What Can You Ask Antigravity to Do for SSL and domains?

Type these as written and swap in your own repository, site and server names. Reads and routine actions such as backups, cache purges, PageSpeed scans and vulnerability scans run straight away; creating, deploying, updating, rebooting, deleting, buying or starting a broken-link scan stops and asks first.

Prompt

Why does staging.example.com show a certificate warning? Check the certificate and the DNS record and explain what you find.

Prompt

Check whether DNS for example.com points at my Frankfurt server, then issue a free certificate if it does.

Prompt

List every domain and additional domain on the shop site and say which one is primary.

Prompt

Check the SSL certificate on shop.example.com and tell me when it expires.

Prompt

Is the DNS A record for example.com pointing at my Frankfurt server yet? Tell me if the Cloudflare proxy is on.

Prompt

Issue a free SSL certificate for example.com once DNS resolves, then confirm the site loads over HTTPS.

Prompt

Renew the certificate on the shop site and tell me the new expiry date.

Prompt

List every domain and additional domain on the shop site and say which is primary.

Prompt

Which of my sites have a certificate that expires in the next 30 days?

Prompt

Use my connected Cloudflare account for the certificate on shop.example.com, and show me what will change first.

Prompt

Visitors get a Cloudflare 526 error on shop.example.com. Check the certificate and tell me what is wrong.

Antigravity and SSL and domains: Frequently Asked Questions

What people ask before they let Antigravity manage SSL and domains through xCloud.

Will Antigravity prompt me before it renews an xCloud certificate?

Yes, twice. Antigravity asks before running an MCP tool you have not allowed, and xCloud requires an explicit confirmation for a renewal or an install. The agent names the site and the provider before it asks.

Can Antigravity explain why a certificate failed to issue?

Yes. It reads the certificate status and runs the DNS check, then explains the likely cause, such as a record that does not yet point at your server or a Cloudflare proxy in the way. It proposes a fix and waits for your approval before changing anything.

Can an AI agent add a domain to an existing site?

No. The API reads a site's domains, additional domains and domain update status, but adding, changing or removing a domain on an existing site is a dashboard step under Site > Domain. A domain is chosen when the site is created. The agent can tell you what is currently set and give you the path.

Which certificate options can the agent install?

Three: xCloud's free Let's Encrypt certificate, a custom certificate you supply, and a certificate through your connected Cloudflare account. The agent checks the current state first and asks before it changes anything. Switching a site from one provider to another needs an explicit override.

Why did the agent say a renewal did nothing?

A normal renewal only fires when the certificate is within seven days of expiry. If you need it earlier, ask for a forced renewal and the agent will confirm before it runs. Renewing also needs the site SSL permission on your team role.

Does the agent set up my DNS records?

It reads and checks them rather than writing them. It can tell you whether a domain's record points at your server and whether the Cloudflare proxy is on. DNS and the certificate are written for you only at site creation, when the domain's zone is on a Cloudflare account you connected to xCloud.

What does the agent do about a Cloudflare 526 error?

It treats it as an SSL problem. It reads the site's certificate status and expiry, and fixes it with an installation or renewal after your approval. A 522 is a different fault, usually closed ports 80 and 443 on the origin, so it is checked against the firewall instead.
