krexel-mcp
This MCP server lets AI assistants deploy, inspect, edit, and manage live static websites via the Krexel hosting platform. Key capabilities include:
Deploy a site (
ship_site): Upload a local build folder to a custom domain. Supports framework hints (Next.js, Astro, Vite, static) and returns adeploy_idand preview URL.List deployments (
list_deploys): View recent deploys from local state, optionally filtered by domain.Rollback (
rollback): Mark a previous deploy as the current good version for a domain.Inspect deploy logs (
get_logs): Retrieve build logs for a specific deploy.List files (
list_files): Get metadata (paths, sizes, SHA256 hashes) for all files in a deployed site.Read a file (
read_file): Fetch the full content of a specific file from a deployed site.Edit a file (
edit_file): Patch a live site usingcreate,replace,replace_all, ordeleteoperations. Changes go live in ~8 seconds as a lightweight patch deploy.Set environment variables (
set_env): Encrypt and persist env vars for a domain using AES-256-GCM encryption.Check account status (
get_status): View account info, deploy count, plan, platform, and state directory.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@krexel-mcpDeploy my new site from the ./dist folder"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
krexel-mcp
Ship AND edit static sites from any AI assistant that speaks the Model Context Protocol.
krexel-mcp is the official MCP server for
Krexel — a "your AI ships and edits your live site"
API. Point any MCP-compatible client (Claude Desktop, Cursor, Windsurf,
VS Code) at this server and your assistant can deploy, list, edit,
rollback, and inspect sites just by talking.
Quickstart
Add krexel-mcp to your MCP client configuration:
{
"mcpServers": {
"krexel": {
"command": "npx",
"args": ["-y", "krexel-mcp"],
"env": {
"KREXEL_API_URL": "https://api.krexel.com",
"KREXEL_API_KEY": "krx_live_••••••••••••••••",
"KREXEL_MASTER_KEY": "<your-32-byte-hex-key>"
}
}
}
}Restart your client. The assistant now sees nine Krexel tools.

Tools
Tool | What it does |
| Upload a built site folder. Returns a |
| Patch a deployed site (create / replace / replace_all / delete). 0.1 deploy. |
| List the files in a deployed site (path + size + sha256). |
| Read one file's content from a deployed site. |
| List recent deploys from local state. Optional domain filter. |
| Fetch build logs for a deploy. |
| Mark a previous deploy as the current good version. |
| Encrypt and persist an env var for a domain (AES-256-GCM). |
| Return account, deploy count, plan, and state directory. |
The conversational-edit flow
AI calls
list_files(deploy_id)to see what files exist on the site.AI calls
read_file(deploy_id, path)to read the file it wants to change.AI generates the new content itself, then calls
edit_file(deploy_id, op: "replace", file, find, value, message).Krexel ships the patch as a new deploy — live in ~8 seconds, 0.1 deploy against the customer's quota. The new
deploy_idandparent_deploy_idare returned so the AI can chain further edits on top.
The AI is the brain. Krexel is the hands.
All tools take plain JSON arguments and return JSON. Tool schemas are
discoverable via the standard MCP tools/list request.
