Install

How do I install the ai.yetty/yetty MCP server?

ai.yetty/yetty is a hosted endpoint at https://mcp.yetty.ai/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 10 exposed · ~1,122 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
yetty_authoring_guide ~94

READ THIS BEFORE WRITING OR SENDING ANY HTML (no account needed, free, instant, no arguments). Returns yetty's exact structure rules — repeated items sharing one class, semantic class names for field labels, headings before sections, no JS-rendered content — that decide whether the site converts into a clean editable CMS with named fields and add/remove collections, or a wall of generic "Text" fields.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

yetty_batch_end ~47

Close the parked batch. Nothing is processed yet — next call yetty_signup {email, park_ref} so the owner can approve by email.

NameTypeReqDescription
batch_refstringyes

No output schema declared.

No examples provided.

yetty_batch_file ~108

Add ONE file to the parked batch. Args: batch_ref (the pk_... park_ref); path (relative, folders allowed); content (text) OR content_base64 (binary). Returns {received_bytes, sha256} — verify against your local copy; mismatch = resend THIS file. Send EXACT bytes, never retype.

NameTypeReqDescription
batch_refstringyes
contentstring
content_base64string
pathstringyes

No output schema declared.

No examples provided.

yetty_batch_start ~153

No account needed: start a PARKED file batch — send the site now, authenticate after. Returns park_ref (use it as batch_ref). Files are stored safely but NOT processed until the owner approves by email. EXAMPLE: yetty_batch_start {} -> {park_ref:"pk_..."} -> yetty_batch_file {batch_ref:"pk_...", path:"index.html", content:"..."} per file -> yetty_batch_end {batch_ref:"pk_..."} -> yetty_signup {email:"owner@x.com", park_ref:"pk_..."} -> owner clicks the email -> yetty_claim_status {park_ref:"pk_..."} gives you an API key + the build status.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

yetty_claim_status ~77

Check a parked upload. States: parked (send yetty_signup) -> awaiting-approval (owner must open the email and type the user_code) -> approved (returns your api_key ONCE + waiting_url — reconnect with Authorization: Bearer <api_key> for the full toolset).

NameTypeReqDescription
park_refstringyes

No output schema declared.

No examples provided.

yetty_login ~123

Sign the OWNER in by email — no dashboard, no key copying. Works for existing accounts AND (when signups are open) new ones. FLOW: yetty_login {email:"owner@x.com"} -> {login_ref, user_code} -> SHOW the owner the user_code; they open the emailed link and type it -> poll yetty_login_status {login_ref} every ~20s -> it returns an api_key ONCE + the exact reconnect command. Use this whenever you are unauthenticated or your token expired.

NameTypeReqDescription
emailstringyes

No output schema declared.

No examples provided.

yetty_login_status ~94

Check an email sign-in: pending (owner has not typed the code yet) -> approved (returns api_key ONCE + reconnect instructions). EXAMPLE reconnect for Claude Code: claude mcp remove yetty; claude mcp add --transport http yetty https://mcp.yetty.ai/ --header "Authorization: Bearer <api_key>" -s user

NameTypeReqDescription
login_refstringyes

No output schema declared.

No examples provided.

yetty_pull_template ~291

Pull a ready-made Yetty template file WITH its usage contract (no account needed, free, instant). Four boilerplates, one per store surface: template:"checkout-skeleton" (cart / checkout / thank-you markup with every data-yetty-component and data-yetty-slot mark), "account-skeleton" (the buyer's /account page in the site's own design), "order-status-skeleton" (the /order/{token} confirmation), "pay-skeleton" (the /pay/{token} frame - the payment element stays hosted and non-removable). Every file carries a commented CONDITIONAL REGIONS section showing the component logic grammar (data-yetty-when / data-yetty-each / data-yetty-state; full grammar in yetty_authoring_guide's logic_and_conditional_components chapter). Restyle freely to match the site; NEVER remove or rename data-yetty-* marks; write NO cart/checkout/account JavaScript of your own (Yetty provides the behavior); send the styled file back with the site files. (Connected Live-plan stores can additionally pull 24 gallery-<surface>-<layout> LAYOUT skeletons - different page structures over the same contract, auto-adjusted to the site's own colors and fonts.)

NameTypeReqDescription
templatestringtemplate key: checkout-skeleton (default) | account-skeleton | order-status-skeleton | pay-skeleton

No output schema declared.

No examples provided.

yetty_signup ~92

Link a parked upload to the owner's email: sends them an approval email and returns a short user_code. The site is processed ONLY after the owner opens the email and types that code on the approval page. Args: email (the owner's), park_ref. SHOW THE OWNER THE CODE, then poll yetty_claim_status every ~30s.

NameTypeReqDescription
emailstringyes
park_refstringyes

No output schema declared.

No examples provided.

yetty_status ~43

Connection + authentication status. Call this FIRST. Unauthenticated sessions can still park a website (batch tools) and start email sign-up — the response tells you exactly how.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

Common questions

What is the ai.yetty/yetty MCP server?

ai.yetty/yetty is an MCP server listed in the public MCP registry as ai.yetty/yetty. Build, edit and run real hosted websites from your AI - content, SEO, menus, store, rollback. This page covers its hosted endpoint (https://mcp.yetty.ai/mcp).

Is the ai.yetty/yetty MCP server safe to use?

ai.yetty/yetty scores 86 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the ai.yetty/yetty MCP server expose?

ai.yetty/yetty exposes 10 tools: yetty_status, yetty_authoring_guide, yetty_pull_template, yetty_batch_start, yetty_batch_file, and 5 more. Their descriptions and schemas cost roughly 1,122 tokens of context every time the server is loaded.

Does the ai.yetty/yetty MCP server require authentication?

Yes. ai.yetty/yetty asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

Is the ai.yetty/yetty MCP server still maintained?

ai.yetty/yetty is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
