Ship sites from Cursor.

Give Cursor nine MCP tools so it can deploy and edit your live site from the chat panel. Two commands, 60 seconds, works in Composer and the regular editor.

The 60-second setup

  1. Install the Krexel CLI and MCP server

    `npm install -g krexel` installs the CLI plus `krexel-mcp`.

  2. Log in once

    `krexel login` writes your auth token to `~/.krexel/auth.json`.

  3. Add the MCP server to Cursor

    Open Cursor → Settings → Features → Model Context Protocol → Add new MCP server. Name: `krexel`. Command: `krexel-mcp`. Type: `stdio`.

  4. Verify the tools are loaded

    Open Cursor Composer (Cmd+I). Ask: "What Krexel tools do you have?" — should list all 9.

  5. Ship your first site

    Ask Composer: "Build a one-page site for a yoga studio and ship it to krexel.app." — done in 30 seconds.

What you can do with it

Edit live from Composer

Select a file in Composer, ask for a change, hit Apply. Composer calls `patch`, the change is live in 8 seconds, you refresh the browser to see it.

Read the live version, not the local copy

Cursor's Composer often works from the local file. With the Krexel MCP, you can ask it to read the deployed file — useful when the local and live versions diverge.

Roll back from the chat

Say "revert that" in Composer. It calls `rollback` with the previous `deploy_id`. The site snaps back in 4 seconds.

Try these prompts

After installing, paste any of these into Cursor to see the deploy/edit workflow:

  • Read the live about page and add a section about our new partnership with Acme Co.
  • Roll back the last change.
  • Create a new contact page with a form that posts to krexel.com/api/contact.

Your key stays yours

Stored in your tool's config. Revoke any time from krexel.com/settings/keys — access cuts off instantly.

Works alongside your other tools

Install in Claude Code, Cursor, Windsurf, and VS Code. Same API key works in all of them.

No lock-in

All Krexel tools wrap a public HTTP API. If you stop using any one AI client, your data and sites stay on Krexel.
