Ship and edit static sites from any MCP-compatible AI. The AI is the brain; Krexel is the hands.
Install
Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).
krexel-mcpclaude mcp add krexel-mcp -- npx -y krexel-mcp@0.3.2{
"mcpServers": {
"krexel-mcp": {
"command": "npx",
"args": [

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 |
|---|---|
ship_site | Upload a built site folder. Returns a deploy_id and preview URL. |
edit_file | Patch a deployed site (create / replace / replace_all / delete). 0.1 deploy. |
list_files | List the files in a deployed site (path + size + sha256). |
read_file | Read one file's content from a deployed site. |
list_deploys | List recent deploys from local state. Optional domain filter. |
get_logs | Fetch build logs for a deploy. |
rollback | Mark a previous deploy as the current good version. |
set_env | Encrypt and persist an env var for a domain (AES-256-GCM). |
get_status | 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.
