How do I connect ChatGPT to xSpeed?
Put your sites in xSpeed Hub once, then add one URL to ChatGPT.
1Put your sites in xSpeed Hub
Sign in at app.xspeedcache.com with Google or email; the Hub is free and has no site cap. Then connect each WordPress site from its own dashboard: click Connect Hub in the xSpeed Cache top bar, then Connect via xSpeed Hub. Each site needs the free xSpeed Cache plugin.
2Turn on developer mode
In ChatGPT on the web, open Settings, then Security and login, and turn on Developer mode. On a Business workspace only admins and owners can use it. On Enterprise and Edu an admin grants access first, and you then turn it on under Settings, Apps, Advanced settings.
Settings > Security and login > Developer mode
3Create the app from the Hub URL
Open ChatGPT Plugins, select the plus button and create a developer-mode app. Name it xspeedhub, paste the MCP server URL and choose OAuth. Click Scan Tools, approve access on the xSpeed Hub page that opens, wait for the scan to list the tools, then click Create. Workspace admins can also start from Workspace settings, Apps, Create.
https://app.xspeedcache.com/xspeed/mcp
4Select the app in a chat
The app appears under Drafts in your app settings with a Dev label. In a new chat, open the plus menu in the composer, choose Developer mode and select xspeedhub. In a workspace, only an admin or owner can publish the app for other members.
+ > Developer mode > xspeedhub
Use the xspeedhub app to list my xSpeed sites and tell me which ones have page caching turned off. Do not change anything.
You: Use the xspeedhub app. Which of my sites has page caching turned off?
list_sites read-only
→ 5 sites: shop, blog, docs, agency, staging
get_cache_status(site: shop) read-only
→ page cache on, 412 cached pages
get_cache_status(site: blog) read-only
→ page cache on, 230 cached pages
get_cache_status(site: docs) read-only
→ page cache on, 96 cached pages
get_cache_status(site: agency) read-only
→ page cache on, 58 cached pages
get_cache_status(site: staging) read-only
→ page cache off, 0 cached pages
ChatGPT: Only staging has page caching off; the other four have it on. Turning it on changes that site's settings. Should I turn it on?
You: Yes, turn it on.
toggle_cache(site: staging, enabled: true) changes site
→ page cache turned on for staging
ChatGPT: Page caching is on for staging. It starts empty, so the first visits will fill the cache. I can start the preloader if you want it warmed.
Using it
Prompts to try in ChatGPT
Paste one as it is, or change the site name.
Use the xspeedhub app: show the cache hit ratio for every site and flag anything under 70%.

Use xspeedhub, read only: which of my sites has an unwarmed cache?
What can ChatGPT do with xSpeed?
A guide for each job, written for ChatGPT.
Purge the WordPress cache with ChatGPT
Clear stale pages after a deploy, an edit or a plugin update, on one site or all of them.
Find out why WordPress pages are not cached with ChatGPT
Work out why a site misses the cache, serves slow pages or shows a low hit ratio, using read-only checks first.
Scan a website for speed problems with ChatGPT
Get a graded speed report with the fix for every failing check and a link you can share, for your own site or any public URL.
Run and track PageSpeed tests with ChatGPT
Read the PageSpeed scores a site already has, run a new test when something changed, and tell a Lighthouse score from a cache benchmark.
Raise a WordPress site's PageSpeed score with ChatGPT
Preview and apply xSpeed's recommended settings to a site, check the pages still work, and be told plainly what caching cannot fix.
Tune WordPress cache settings with ChatGPT
See which modules a site has, read their current settings, change them, and turn page caching on or off.
Warm the WordPress cache with ChatGPT
Fill the page cache before visitors arrive, for example right after a purge or a deploy.
Set up the Redis object cache with ChatGPT
Connect a site to Redis or Memcached so database results survive between requests.
Manage Cloudflare caching with ChatGPT
Check the Cloudflare connection, clear the edge cache and switch development mode on or off for a site.
Manage every WordPress site at once with ChatGPT
Run one action across all of your sites, or a chosen few, and read the result site by site.
Trust and safety
Does ChatGPT ask before it changes my site?
ChatGPT asks you to confirm write actions by default. You can expand a tool call to read the JSON it will send, and you can choose to remember an approve or deny choice for a tool for the rest of that conversation. ChatGPT respects a tool's read-only annotation and treats a tool without one as a write action; xSpeed Hub's tool definitions do not declare that annotation today, so expect confirmations on reads as well. OpenAI says confirmation also depends on app permissions and context, and some especially risky actions can be blocked. xSpeed Hub has no confirmation step of its own, so once you tell ChatGPT to remember Approve for a tool, that tool runs without a prompt for the rest of the conversation, as soon as your connection allows writes.
xSpeed Hub
xSpeed Hub has no confirmation step of its own. Read tools change nothing on your sites, with one exception to know about: contact_support sends an email to xSpeed support, and a read-only connection can still call it. A write tool (a purge, a settings change, a cache toggle, or a speed test that spends the shared allowance) runs as soon as your connection allows writes. Three things stand between a prompt and a change: your connection's scope, because a read-only connection refuses every write tool (the connection token has a Read-only everywhere switch, and a Viewer member only ever gets read access); your AI client's own tool-approval prompt; and the Hub's instructions to the agent, which tell it to confirm the target site and to ask once before a write that touches every site.
Good to know
- Plan limits differ between OpenAI pages. The developer-mode guide lists Pro, Plus, Business, Enterprise and Edu on the web, while the help center describes full MCP with write actions as a beta for Business, Enterprise and Edu and says Pro connects with read access. If the Hub's write tools are missing, check your plan with OpenAI.
- Custom MCP apps are web only. OpenAI says agent mode does not use custom apps, and deep research uses them for read and fetch only, not writes.
- OpenAI notes that OAuth connections can lose access and ask you to reauthenticate when the provider does not advertise the offline_access scope. The Hub lists the scopes read and write. If ChatGPT asks you to sign in again, approve access again.
- After an admin publishes an app, ChatGPT works from a snapshot of its tools. If the Hub adds tools later, an admin refreshes the actions in Workspace settings.
Reference
What is ChatGPT?
ChatGPT is OpenAI's AI assistant. Its developer mode gives ChatGPT on the web full MCP client support for custom apps, including write tools, so a chat can call tools on a remote MCP server that you register.
MCP, the Model Context Protocol, is how those tools are described to the model. Registering xSpeed Hub as an app gives ChatGPT the Hub's caching tools for every site in your workspace. OpenAI labels developer mode as elevated risk and warns about prompt injection and model mistakes on write actions. ChatGPT signs in with OAuth and gets the scopes it asks for, which are read and write. The Hub's Read-only everywhere switch applies only to the connection token, which ChatGPT cannot send, so for read-only access sign in as a Viewer member of the workspace.

Why use ChatGPT with xSpeed?
A confirmation you can read
ChatGPT shows each tool call with its input and output. Expand it before you approve a purge or a settings change, and see exactly which site and which options it will send.
Reads and writes in the same chat
Ask for the status, hear the diagnosis and approve the fix in one conversation. The agent lists your sites first, so you can name a site in plain words.
Share it with a workspace
On Business, Enterprise and Edu plans an admin can publish the app so members can use it, and Enterprise and Edu admins can switch individual tools on or off after publishing.
How does ChatGPT compare with other AI clients?
Every client below reaches the same 29 Hub tools once connected. What differs is where it runs, how you add the server and how it signs in.
| Client | Made by | Type | How you connect it | Sign-in |
|---|---|---|---|---|
| ChatGPT | OpenAI | Chat app | Developer mode, then a custom MCP app | OAuth sign-in |
| ChatGPT dots | OpenAI | Always-on agent | the xspeedhub app from ChatGPT developer mode, shared through Plugins | OAuth sign-in |
| Codex | OpenAI | Terminal | codex mcp add --url, then codex mcp login | OAuth sign-in or connection token |
| Claude | Anthropic | Chat app | Customize, Connectors, Add custom connector | OAuth sign-in or connection token |
| Claude Code | Anthropic | Terminal | claude mcp add, then /mcp to sign in | OAuth sign-in or connection token |
