Skills for agents that ship HTML.

Task-oriented abilities your agent installs in one command. Publish artifacts to private URLs, migrate sites off website builders, pay for hosting autonomously. Each works in Claude Code, Codex, Cursor, and any agent that reads the skills format.

What skills can an AI agent install for Stacktree?

Three abilities, one command each: publish (the stacktree-publish skill pipes any HTML artifact to a private URL), migrate (the website-builder-migrate skill moves a site off Webflow, Framer, or Squarespace), and pay (any x402 client lets the agent buy its own API key for $1 on Base mainnet). The MCP server covers the same ground as native tool calls for MCP-speaking agents.

publish

Pipe any HTML artifact to a private URL the moment it exists.

Install

Then

"publish this dashboard and give me the link"

The agent pipes the file to stacktr.ee and returns a private, unguessable URL into the conversation. No project, no build, no DNS.

  • ◇ Anthropic Skills format: works in Claude Code, Codex, Cursor, OpenCode, and any agent that reads SKILL.md.
  • ◇ Private by default; the URL is the credential, viewers need no account.
  • ◇ Replace-in-place: revising the artifact keeps the same URL.

connect · mcp

Give your agent the publish_html tool over MCP, with gates and expiry.

Install

Interactive: signs you in and writes the MCP config for Claude Code, Cursor, Codex, or a plain JSON snippet.

Then

› publish_html(dashboard.html)

The MCP server is the richer surface: update_site, set_password, set_email_gate, set_expiry, list_sites, delete_site, all as tool calls.

  • ◇ One MCP server, every client: Claude Code, Claude.ai, Cursor, Codex, raw HTTP.
  • ◇ Gating as tool calls: passwords, email-domain gates, expiry, burn-after-read.
  • ◇ Remote server at api.stacktr.ee/mcp if you would rather not run anything locally.

migrate

Move a site off Webflow, Framer, or Squarespace, and verify it in private.

Install

Then

/website-builder-migrate https://yourdomain.com/

Seven phases: mirror, consolidate, rewrite URLs, fix the five known breakages (SRI blocks, lazy chunks, double-encoded filenames), verify in-browser, deploy.

  • ◇ Platform-agnostic, with per-builder notes; Wix honestly flagged as static-template-only.
  • ◇ Captures rendered CMS pages that Webflow's paid export omits.
  • ◇ Deploys anywhere; the no-account path publishes a 24-hour private preview for checking against the original before DNS moves.

pay · x402

Let the agent buy its own key and unlocks. No card, no account, no human.

Install

Third-party x402 client skill (any works, e.g. @x402/fetch); point it at our endpoints with a funded Base wallet.

Then

POST https://api.stacktr.ee/provision

Answers 402 with terms; the agent signs a gasless USDC authorization and gets a persistent stk_live_ key for $1. Unlocks (custom domain, higher limits) work the same way. No wallet? POST /pay/sessions prints a QR a human pays by card, and surplus becomes a balance future actions draw silently.

  • ◇ Live on Base mainnet, x402 v1 and v2; the catalog is public at GET /unlock.
  • ◇ Scan-to-pay fallback: one QR scan funds a prepaid balance ($5 to $20).
  • ◇ The whole loop is real: an agent paid us $1 and published a page that is still up.
FAQ

Frequent questions

What is an agent skill? +
A folder with a SKILL.md instruction file (plus optional scripts) that an agent loads when the task matches. The format originated with Anthropic Skills and is now read by Claude Code, Codex, Cursor, OpenCode, and others, so one skill works across agents. Install is one command: npx skills add owner/repo.
Skill or MCP server: which should I install for publishing? +
Either works; they differ in surface. The skill is the lightest path: instructions plus a publish script using your API key. The MCP server exposes the full toolset (update_site, passwords, email gates, expiry, listing, deletion) as native tool calls. If your agent speaks MCP, the server is the better default; the skill suits restricted environments.
Can an agent set this up with no human involved? +
Yes, end to end. Skills install from public repos without auth. The API key normally requires a human dashboard login, but an agent with a funded Base wallet can buy its own persistent key for $1 over x402, and an agent without a wallet can print a QR code its human pays by card in two taps. Both paths are live in production.
Are the skills free? +
Yes. Both Stacktree-maintained skills are open source on GitHub, and the third-party x402 client skill is too. Hosting itself has a free tier (5 permanent sites at 25 MB); paid actions are a-la-carte ($1 to provision, $1 make-permanent, $5 / 30 days for a custom domain or higher limits).
