Kleap — website infrastructure for AI agents

Your agent builds. Kleap ships it live. Let any AI agent — Claude, ChatGPT, Cursor — build, edit and publish real, live websites for you. Hosting, database, auth and domains included.

An alternative to Lovable / v0 / Bolt — except it's driven by your agent, and every publish comes with the verified-live guarantee: a site is only ever reported online once it is provably serving — never a hallucinated dead link.

This is a thin Model Context Protocol server that wraps Kleap's public REST API. No secrets live in this package — it reads your own KLEAP_API_KEY from the environment and talks only to kleap.co.

Quick start

1. Get an API key — at kleap.co → Settings → API key → MCP / API access → Generate MCP key (kleap_live_sk_...).

2. Add Kleap to your AI client:

<details open> <summary><b>Claude Desktop</b> — <code>claude_desktop_config.json</code></summary>

{
  "mcpServers": {
    "kleap": {
      "command": "npx",
      "args": ["-y", "github:Kleap-co/kleap"],
      "env": { "KLEAP_API_KEY": "kleap_live_sk_..." }
    }
  }
}

</details>

<details> <summary><b>Cursor</b> — <code>.cursor/mcp.json</code></summary>

{
  "mcpServers": {
    "kleap": {
      "command": "npx",
      "args": ["-y", "github:Kleap-co/kleap"],
      "env": { "KLEAP_API_KEY": "kleap_live_sk_..." }
    }
  }
}

</details>

<details> <summary><b>ChatGPT & hosted agents</b> — no local process</summary>

Add the hosted connector at https://kleap.co/api/mcp and authorize with OAuth (or paste your kleap_live_sk_ key). </details>

Once published to npm, the install shortens to "args": ["-y", "kleap"].

3. Restart the client and just ask:

"Build me a one-page site for my bakery, publish it, and give me the live URL." "Add a contact form to my site and redeploy." "Change the headline to 'Roasted slow' and publish."

Works with any MCP-compatible agent: Claude · ChatGPT · Cursor · Claude Code · Codex.

Tools

Build — create_app · modify_app · check_task · retry_task Publish & domains — publish_app · get_publish_status · search_domains · check_domain · connect_domain Account — list_apps · get_app · list_app_files · get_credits

Tool	What it does
create_app	Create a site from a prompt → returns a task
modify_app	Ask the app's AI to change it → returns a task
check_task	Poll a create/modify task to completion
retry_task	Resume a failed/stalled build from partial state
publish_app	Publish with verified-live (live-or-rollback, never a false "online")
get_publish_status	Confirm a site is actually published + live
search_domains	Find available domains (purchase stays user-confirmed in Kleap)
connect_domain	Connect a domain you already own to a published app
check_domain	A domain's connection / DNS status
list_apps / get_app / list_app_files	Your apps, an app's details, its files
get_credits	Remaining credit balance + plan

App arguments are snake_case: app_id, task_id, prompt, message, visibility.

The verified-live guarantee

Most tools tell the agent "it's online" the moment a deploy is requested. Kleap reports a site as published only once the new version is provably serving at its live URL — otherwise it rolls back and reports "not confirmed live." Your agent can never hand a user a dead link.

If check_task reports failed (a transient generation stall), call retry_task with the same task_id to resume from where it stopped — partial work is kept.

FAQ

Is it safe? Yes. The connection uses your private kleap_live_sk_ key; an agent can only touch your own Kleap apps. The key stays in your local client config, is sent only to kleap.co over HTTPS, and is revocable anytime in Settings → API key. Nothing is written to disk.

How much does it cost? Connecting is free. Builds and edits use Kleap credits (get_credits reports your balance) — see pricing.

Which agents work? Any MCP client: Claude Desktop, Claude Code, Cursor, ChatGPT (hosted connector), and others.

Requirements & run

Node ≥ 18. Run it directly:

KLEAP_API_KEY=kleap_live_sk_... npx -y github:Kleap-co/kleap
# → [kleap-mcp] ready (stdio) → https://kleap.co. Tools: list_apps, ...

Override the API base with KLEAP_API_URL (default https://kleap.co). Missing key → the server exits with a clear message.
