Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security94
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents. View diagnostics → Partial
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability60
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 2701 tokens (~270/item across 10 items; 10 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage70
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 9% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 10 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
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.

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 →
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.
| Name | Type | Req | Description |
|---|---|---|---|
| batch_ref | string | yes | – |
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.
| Name | Type | Req | Description |
|---|---|---|---|
| batch_ref | string | yes | – |
| content | string | – | – |
| content_base64 | string | – | – |
| path | string | yes | – |
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).
| Name | Type | Req | Description |
|---|---|---|---|
| park_ref | string | yes | – |
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.
| Name | Type | Req | Description |
|---|---|---|---|
| string | yes | – |
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
| Name | Type | Req | Description |
|---|---|---|---|
| login_ref | string | yes | – |
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.)
| Name | Type | Req | Description |
|---|---|---|---|
| template | string | – | template 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.
| Name | Type | Req | Description |
|---|---|---|---|
| string | yes | – | |
| park_ref | string | yes | – |
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.
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.
