Stacktree
Ship a private HTML preview link from your agent without standing up hosting or exposing a public URL.
Overview
Stacktree is a MCP server for the Validate phase that publishes HTML to private, replace-in-place URLs from MCP-compatible AI agents.
What is this MCP server?
- Publishes HTML to private, unguessable URLs usable from any MCP-compatible agent
- Replace-in-place updates on the same secret link—no redeploy choreography
- Remote streamable HTTP at https://api.stacktr.ee/mcp plus npm stdio package stacktree-mcp v0.2.1
- Streamable-http remote and stdio transport for Claude Code, Cursor, and Codex workflows
- Backed by open-source stacktree-mcp on GitHub (stevysmith/stacktree-mcp)
- Server version 0.2.1 (registry and npm package)
- Dual access: remote streamable-http + npm stdio identifier stacktree-mcp
What problem does it solve?
You have HTML ready in chat but no fast, private way to share it for feedback without deploying a full site or leaking a public URL.
Who is it for?
Solo builders validating landing pages, pitch decks-as-HTML, or prototype UIs who already work in Claude Code, Cursor, or Codex.
Skip if: Teams needing SSO, SEO-indexed marketing sites, server-side apps, or long-term production hosting with SLAs.
What do I get? / Deliverables
Your agent can push HTML to a stable secret link you can refresh in place until you are ready to ship on real hosting.
- Private, unguessable URL serving your published HTML
- Same URL updated when you publish revised HTML in place
Recommended MCP Servers
Journey fit
Validate-phase work often needs shareable one-pagers and landing drafts before DNS, auth, or production deploy exist. Landing and prototype sharing maps directly to unlisted, replace-in-place HTML URLs for feedback loops.
How it compares
Ephemeral HTML publish MCP, not a static host skill or full Jamstack deploy pipeline.
Common Questions / FAQ
Who is Stacktree publish for?
Indie builders and agent-first developers who need private, shareable HTML previews during validation—not production DevOps.
When should I use Stacktree publish?
Use it when you want feedback on a landing page, one-pager, or HTML mock before you buy a domain or wire CI/CD.
How do I add Stacktree publish to my agent?
Add the streamable-http remote https://api.stacktr.ee/mcp in your MCP client, or install npm package stacktree-mcp (stdio) from the MCP registry entry.
