Ship websites from any MCP-compatible AI assistant. Deploy, list, rollback, logs, env.
Krexel MCP server exists for a simple reason — assistants are far more useful when they can act on Krexel directly instead of describing what you should do. Ship websites from any MCP-compatible AI assistant. Deploy, list, rollback, logs, env.
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.
Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
Once Krexel is connected, these are the calls the assistant has available:
ship_site — Upload a built site folder. Returns a deploy_id and preview URLedit_file — Patch a deployed site (create / replace / replace_all / delete). 0.1 deploylist_files — List the files in a deployed site (path + size + sha256)read_file — Read one file's content from a deployed sitelist_deploys — List recent deploys from local state. Optional domain filterget_logs — Fetch build logs for a deployrollback — Mark a previous deploy as the current good versionset_env — Encrypt and persist an env var for a domain (AES-256-GCM)get_status — Return account, deploy count, plan, and state directoryYou will need 3 environment variables: KREXEL_API_URL, KREXEL_API_KEY, KREXEL_MASTER_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Among the cloud and infrastructure options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Krexel's toolset — ship_site, edit_file, list_files and 6 more — is a fair guide to whether it matches your workflow. It is maintained by Syfer-web; worth a glance at recent repository activity before you build anything load-bearing on it.
