Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 1184 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name noback.

  • Pass
    Lists tools

    tools/list returned 4 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 1184 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 1184 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    9 of 9 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-10-25T12:19:55.372848Z, within 180 days.

Capabilities

Tools 4

create_app

Publishes a new app with no account or token, from html or zipBase64. It runs the same checks as validate_app (errors make it fail, with the list and how to fix them). The app is deleted if nobody uses it for 30 days, and it can reach the internet only through the services on noback's list. Its link opens your copy: whoever opens it sees what you entered and can leave their own things (comments, sign-ups, orders) without touching anyone else's; if the app asks for sensitive data, everyone starts their own empty copy. Returns appId, version, openUrl, editKey, claimUrl, message and warnings. Tell the person message ("Your app is ready: <openUrl>") in the language of the conversation, with no extra explanations. Then ask them once "Want to save it to your account?" (in the language of the conversation) and give them claimUrl only if they say yes: it's private, only for that person, and lets them keep the app. Keep appId and editKey to publish changes to THIS same app with update_app; don't create another one. Never put editKey or claimUrl in the HTML, the data or a shared link.

Discovered
get_sdk

Returns noback's guide for writing apps (in English, as Markdown in `markdown`): how to make a single-file HTML app whose data is saved and shared (localStorage, window.storage or app.db), what works inside noback and what doesn't, packages, limits and how to publish. Read it once before writing or changing an app for noback. Read-only.

Discovered
update_app

Publishes a new version of the same app without an account, using the appId and editKey from create_app, with the same checks as create_app. The data and the shared link stay as long as you keep the same app.db collections and fields and the same localStorage keys. Returns openUrl, version, message and warnings. Tell the person openUrl in the language of the conversation; give them claimUrl (private) only if they want to save the app to their account.

Discovered
validate_app

Checks an app (html or zipBase64) against noback's rules, with the limits of an app without an account, without publishing anything or running its code. Use it before create_app or update_app. Returns { ok, errors, warnings }; each item has a code, a message and a fix. Fix every error before publishing; warnings are suggestions and the app works anyway. Without an account, the app can reach the internet only through the services on noback's list. If warnings include NO_APP_DB with certain: true, the app loses what people enter when the page reloads: save it in localStorage (the warning's prompt says what to change) before publishing. If warnings include STATIC_LIST, the content is written by hand in the page: offer to make it editable from the page, with only the owner writing (the warning's prompt says what to ask for). Read-only.
