What your AI can do with it

Install Yetty MCP Server

The server’s own address, for the clients that take one directly. Or connect Ahel once and every client you use reads it from one address, with the account kept on Ahel rather than in each client’s config.

  • Claude Code

    claude mcp add --transport http --scope user yetty-mcp-server 'https://mcp.yetty.ai/mcp'

    Run it once in your project, then open /mcp to approve any sign-in the server asks for.

  • Claude Desktop

    https://mcp.yetty.ai/mcp

    Add a custom connector in Settings, paste this address, and approve the sign-in.

  • Cursor

    cursor://anysphere.cursor-deeplink/mcp/install?name=yetty-mcp-server&config=eyJ1cmwiOiJodHRwczovL21jcC55ZXR0eS5haS9tY3AifQ==

    Open the link and Cursor adds the server at that address.

  • ChatGPT

    https://mcp.yetty.ai/mcp

    In Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.

  • Codex

    codex mcp add yetty-mcp-server --url 'https://mcp.yetty.ai/mcp'

    Run it once, then sign in with codex mcp login yetty-mcp-server if the server asks for an account.

From the project's README

As published by avniy/yetty-mcp in README.md.

Run a real, hosted website from your AI. Yetty turns any static HTML into a fully managed, hosted site with a CMS built around it - byte-true, nothing redesigned - and this MCP server is the control plane: your AI can build, edit, publish and monitor the site end to end.

  • Remote server: https://mcp.yetty.ai/mcp (Streamable HTTP)
  • Auth: OAuth 2.0 (PKCE + dynamic client registration) - or a yk_ API key as a Bearer header
  • Registry: published as ai.yetty/yetty in the official MCP Registry

What your AI can do with it

AreaTools
Build & convertcreate a site from HTML/zip, upload in chunks, start the free conversion, reprocess through the latest engine
Contentedit any text/image field, compose posts, manage collections and items, menus, taxonomies and terms, global content, translations
Publishpublish with a version history, check readiness, roll back anything, staged drafts with one publish door
GrowSEO (titles, descriptions, robots, AI-crawler policy), site search, redirects, permalinks, sitemaps + llms.txt
Runreal traffic analytics (incl. browsers, devices, referrer types, countries), leads inbox, forms, integrations/webhooks, link checks
Commercestore status and readiness (Yetty Shops)

Every mutation lands as a rollbackable version - nothing is ever lost.

Connect

Claude (claude.ai / Claude Desktop)

Settings → Connectors → Add custom connector → https://mcp.yetty.ai/mcp → sign in with your Yetty account (OAuth).

Claude Code

claude mcp add --transport http yetty https://mcp.yetty.ai/mcp
# or with an API key instead of OAuth:
claude mcp add --transport http yetty https://mcp.yetty.ai/mcp --header "Authorization: Bearer yk_your_key"

Cursor / Windsurf / VS Code (and any client with remote MCP)

{
  "mcpServers": {
    "yetty": {
      "url": "https://mcp.yetty.ai/mcp",
      "headers": { "Authorization": "Bearer yk_your_key" }
    }
  }
}

ChatGPT / Grok / other MCP-capable apps

Add a remote MCP connector pointing at https://mcp.yetty.ai/mcp. Clients that support OAuth sign in with your Yetty account; the rest use a yk_ API key in the Authorization: Bearer header.

Local stdio bridge (no remote-MCP support)

yetty-mcp.py in this repo is a zero-dependency Python bridge:

{
  "mcpServers": {
    "yetty": {
      "command": "python",
      "args": ["/path/to/yetty-mcp.py"],
      "env": { "YETTY_API_KEY": "yk_your_key" }
    }
  }
}

Getting a key

  1. Sign up free at yetty.ai
  2. Dashboard → API Keys → Create API key (shown once)
  3. Or skip keys entirely: use OAuth from any connector-capable client.

Full client-by-client setup: yetty.ai → Dashboard → Connect your AI.

Notes for builders

Before sending a site, call the free yetty_authoring_guide tool - it returns the structure rules (repeated items share one class, semantic class names, headings before sections, no JS-rendered content) that decide how clean the generated CMS is. Conversion is free; hosting plans are per site.
