#  Publish HTML from Cursor with one command.

   Run npx stacktree-install — pick Cursor when prompted — and every HTML file the agent writes can be published to a private, unguessable URL. Replace-in-place via update_site means the same URL survives every revision.

##  How do you publish HTML from Cursor in 2026?

Run `npx stacktree-install`, pick Cursor when prompted, restart Cursor, and ask the agent to publish any HTML file. Stacktree returns an unguessable URL you can password-protect, email-gate, expire, or replace in place. Sites belong to your account from the first publish.

## The 30-second install

 Run `npx stacktree-install` in your terminal. It opens your browser, signs you in to stacktr.ee, and writes the `stacktree` entry into the Cursor `mcp.json` you pick — per-project at `.cursor/mcp.json`, or per-user at `~/.cursor/mcp.json`. Restart Cursor to pick up the new server.

## What the installer writes (for the curious)

 If you'd rather edit `mcp.json` by hand, the entry the installer adds looks like:

```
`{
  "mcpServers": {
    "stacktree": {
      "command": "npx",
      "args": ["-y", "stacktree-mcp"],
      "env": { "STACKTREE_API_KEY": "stk_live_…" }
    }
  }
}`
```

 Generate the key from [app.stacktr.ee/api-keys](https://app.stacktr.ee/api-keys) if you go this route.

## What the agent gets

 Twenty-nine tool calls become available to the Cursor agent: `publish_html`, `update_site`, `delete_site`, `restore_site`, `claim_site`, `set_password`, `set_expiry`, `create_share_link`, `list_share_links`, `revoke_share_link`, `set_agentation`, `set_client_feedback`, `set_email_gate`, `list_sites`, `get_me`, `list_client_spaces`, `set_client`, `create_client_space`, `update_client_space`, `delete_client_space`, `get_design_guide`, `get_site`, `get_content`, `get_passcode`, `list_versions`, `restore_version`, `list_feedback`, `resolve_feedback`, `link_wallet`. The agent uses them like any other MCP tool — Cursor decides when to call them based on the prompt.

## Typical flow

  - Cursor generates a single-file HTML report.
 - You: "publish that as a private Stacktree, gate it to @yourco.com, expire in 7 days."
 - Cursor calls publish_html, then set_email_gate, then set_expiry. Three tool calls, one operation in your head.
 - You paste the URL into Slack. Anyone with a verified @yourco.com email opens it via magic link.

## When iterating

 If you ask Cursor to revise the same artifact, tell it to "update the same Stacktree" — it'll call `update_site` with the existing slug. The URL doesn't change; the content does. Anyone who already opened the link sees the new version on refresh.

##
Set up Cursor in one line

Paste this into Cursor. It fetches the setup instructions, installs Stacktree,
        checks the connection, and learns the parts agents usually get wrong: replacing a
        page in place so a link you already sent keeps working, reading the real expiry
        instead of promising permanence, and filing work under the client it belongs to.

```
`Fetch and follow the setup instructions at https://stacktr.ee/prompt.md`
```

Works in any agent that can fetch a URL. Nothing to install first, and
[the instructions](/prompt.md)
are plain Markdown you can read before you run them.

FAQ

## Frequent questions

     How do I add Stacktree to Cursor? +  Run `npx stacktree-install` and pick Cursor when prompted. It signs you in to stacktr.ee in your browser, then writes a `stacktree` entry to your Cursor `mcp.json` (per-project `.cursor/mcp.json` or per-user `~/.cursor/mcp.json` — your choice during install). Restart Cursor and the tool calls become available.   Does Cursor support stdio MCP? +  Yes — Cursor implements MCP over stdio, which is exactly what `stacktree-mcp` defaults to. No HTTP wiring required.   Can the Cursor agent replace a previous publish? +  Yes. Tell it to "update the same site" and it calls `update_site`. The URL stays stable across iterations, so any link your team has bookmarked still shows the latest version.   Do I need a Stacktree account to start? +  No. The first publish is anonymous and lives 24 hours. `stacktree login` stores a token at `~/.stacktree/credentials` when you want persistence.   Is this Cursor-specific? +  No. The same `stacktree-mcp` package works in Claude Code, Codex CLI, Claude.ai connectors, and any MCP-compatible client. Cursor just needs the standard mcp.json entry.
