How Zed handles this
You are in Zed with the agent panel open, and the site you just updated still looks old when you load it outside your session. Ask the agent about Cloudflare for that site. It calls list_sites to find the handle, then cloudflare_verify to check whether the credentials and zone saved in xSpeed still resolve. The result appears in the panel beside your open files.
Next the agent can call purge_cloudflare to clear only the edge copy, or set_cloudflare_dev_mode to bypass the edge for about three hours so origin changes show immediately. Both writes need Cloudflare connected in xSpeed on that site, and neither accepts site: "all", so each call names one site.
Zed's default tool permission is confirm, which asks before every tool action, MCP reads included. You will see a prompt even for cloudflare_verify, which changes nothing, and you read each Cloudflare call and its arguments before it runs. To quiet the read, add a per-tool entry, mcp:xspeedhub:cloudflare_verify, with a default of allow. The Always for tool button in the prompt writes the same entry. Zed documents only tool-level entries for MCP tools, with no wildcard, so you allow each read one at a time and the two writes stay on confirm. Setting the global default to allow would loosen every tool, not just xSpeed. After the chore, ask the agent to list the calls it made, so the thread records which site was touched and by which tool.

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.
2Add xSpeed Hub as a remote server
Open Settings, then AI, then MCP Servers, click Add Server and choose Add Remote Server. Or run zed: open settings file and add the entry yourself. Zed calls MCP servers context servers, so the key is context_servers.
{
"context_servers": {
"xspeedhub": {
"url": "https://app.xspeedcache.com/xspeed/mcp"
}
}
} 3Sign in
Because the entry has no Authorization header, Zed prompts you to authenticate against the server with the standard MCP OAuth flow. Approve access on the xSpeed Hub page that opens. There is no token to paste. Back in Settings, AI, MCP Servers, a green dot beside xspeedhub with the tooltip Server is active means it is connected.

Before you send a prompt that changes something
Reads change nothing on your sites, though contact_support emails xSpeed support. Writes run once your connection allows them, so your client's approval prompt and a read-only connection (the token's Read-only everywhere switch, or a Viewer sign-in) are the gates that matter. The Zed agent confirms before it runs any tool action. The default setting, agent.tool_permissions.default, is confirm, and that covers MCP tool calls, reads included. A per-tool entry such as mcp:xspeedhub:get_cache_status with a default of allow lets that one tool run without a prompt, and the Always for tool button in the prompt writes the same entry. Setting the global default to allow auto-approves every tool, writes included, and then a write reaches the Hub as soon as your connection allows writes. xSpeed Hub has no confirmation step of its own.
What do I ask?
Three prompts written for Zed. More for this job are below.
With xSpeed Hub, run a Cloudflare check on shop and tell me exactly what came back.
Use xSpeed Hub to purge only the Cloudflare edge cache on blog.
With xSpeed Hub, turn on Cloudflare development mode for shop while I debug the header, and keep a note to turn it off.
What happens, step by step
When Cloudflare sits in front of a WordPress site, it keeps its own copy of your files at the edge. Through xSpeed Hub an agent can check that the site's Cloudflare credentials still work, purge the edge cache, and turn development mode on or off. All three need Cloudflare connected in xSpeed on that site, and each works on one site at a time.
01
Verify the connection
cloudflare_verify calls Cloudflare's API with the credentials stored on the site and checks that the token and zone still resolve. It purges nothing and works on a read-only connection. If Cloudflare is not connected on that site, the call comes back as an error and the agent should tell you rather than retry.
02
Purge the edge
purge_cloudflare empties the Cloudflare edge cache for the site's zone. It does not touch the copies on your server. When Cloudflare is in front of a site, a content change usually needs both, so the agent runs purge_cache first and purge_cloudflare after it, or one purge_cache of type all, which reaches the edge when Cloudflare is connected.
03
Turn development mode on to see origin changes
set_cloudflare_dev_mode with enabled true bypasses the edge for about three hours, so changes on the origin show immediately. It slows the site for real visitors the whole time. Your client's prompt is the gate here, because the Hub's instructions do not name this tool in their confirm list.
04
Turn it off when you finish
set_cloudflare_dev_mode with enabled false switches development mode off. Cloudflare also ends it on its own after about three hours. No Hub tool reads whether it is currently on, so note when you turned it on.
05
Read a failure
A rejected token, an empty zone ID or a refused call comes back as an error that names the action, the HTTP status and Cloudflare's message when it gave one. It is not reported as a success. The credentials themselves are set in the xSpeed Cache panel in wp-admin, not through the Hub.
Reference
| Read tool | cloudflare_verify; purges nothing and works on a read-only connection |
|---|---|
| Write tools | purge_cloudflare and set_cloudflare_dev_mode (enabled true or false) |
| Needs | Cloudflare connected in xSpeed on that site: integration on, an API token (or the legacy key and email) and a Zone ID |
| Edge purge scope | Everything Cloudflare holds for the site's zone; the server copies stay |
| Development mode | Bypasses the edge for about 3 hours, then Cloudflare switches it off |
| Token permissions | Zone Cache Purge, and Zone Settings Edit for development mode |
| What verify proves | The token and zone resolve; a token without Zone Settings Edit still verifies |
| Through purge_cache | Type all also clears the edge when Cloudflare is connected; page, assets, object and rest do not |
| Every site at once | None of the three accept site: "all"; one site per call |
| Failure shape | An error with the action, the HTTP status and Cloudflare's message |
| Read-only connection | The connection token with Read-only everywhere on, or a Viewer member's sign-in; purge_cloudflare and set_cloudflare_dev_mode are refused and cloudflare_verify works. An OAuth sign-in gets the scopes the client asks for, so the switch does not make it read-only |
| Confirmation | None on the Hub; your client's prompt is the gate |
Rules worth keeping
- Run cloudflare_verify first, but do not read a pass as proof that every call will work. A token that lacks Zone Settings Edit verifies and purges fine, then fails the first time development mode is switched.
- Purge the server and the edge together after a content change. Purging only the site leaves visitors on the old page until the edge copy expires.
- Turn development mode off as soon as you are done. It slows the site for real visitors for up to about three hours, and no tool reports its state.
- Never paste a Cloudflare token or Global API Key into the chat. Connect Cloudflare in the xSpeed Cache panel in wp-admin, and use a scoped API token rather than the Global API Key.
- purge_cloudflare and set_cloudflare_dev_mode are write tools. The Hub runs them as soon as your connection allows writes, so your client's approval prompt and a read-only connection (the connection token with Read-only everywhere on, or a Viewer member's sign-in) are the gates that matter.
Good to know with Zed
Because Zed confirms every tool call by default, you will approve cloudflare_verify as well as the writes, and it is tempting to set the global default to allow just to stop that. Do not: that default covers every tool, so it would let set_cloudflare_dev_mode and purge_cloudflare run without a prompt, and the Hub adds none. Add a per-tool allow entry for cloudflare_verify instead, and keep the confirmation for the two Cloudflare writes. These settings apply to the native Zed agent. External agents and terminal threads follow their own configuration.
