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_id and parent_deploy_id are 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.

Configuration

Env var	Required	Default	Notes
