Is duan-online live?

Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.

Is duan-online free to use?

Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.

What tools does duan-online have?

16 tools: List links, Connect account, Create a short link, QR image (PNG or SVG), Shorten URL, Batch shorten, Get link, Inspect short link, ….

Is duan-online safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• get_links auth-required never probed

  List links this account owns. cursor and limit match GET /v1/links. Requires links:read.

  mcpget_links

• begin_registration reads auth-required never probed

  Fallback when the client cannot start OAuth. Returns a browser registration link. Does not create an account, accept a password, or accept terms.

  mcpbegin_registration

• createLink auth-required never probed

  Creates a short URL. Anonymous callers share rate limits with the web create form. Session cookie and API key are optional for basic create. With either, the link belongs to that account and counts toward its monthly limit. Verify your email to raise your limit. Request body must include **exactly one** of `url` or `longUrl` (OpenAPI `oneOf`). Optional `alias` / `customSlug`: if both are sent they must match (case-insensitive); otherwise **409** `FIELD_CONFLICT`. User aliases are folded to lowercase before persistence. A custom alias requires a verified email: session or user API key → **403** `EMAIL_UNVERIFIED` (`email_unverified`); anonymous → **403** `AUTH_REQUIRED` (`alias_requires_verified_account`). An OAuth access token is not an API key here: presenting one is 401 and does not fall through to anonymous create.

  restcreateLink

• getLinkQr auth-required never probed

  Owner-only. Returns a QR code image that encodes the link's `qr_tracking_url` (tagged short URL; ASCII host in the matrix). Default format PNG size 512. `format=png|svg`. PNG `size` is 256, 512, or 1024 (SVG ignores size). Requires a session cookie or an API key with `links:read`. An OAuth access token is not accepted. Anon → 401. Other-user / unowned → 404. Destination is never fetched or encoded. Fetching it does not record a visit. MCP create_qr may also return a short-lived image_url. Returns the stored link's QR as PNG, or SVG when requested, with a short-lived image URL where available. The QR encodes qr_tracking_url. Where an image is not displayed, image_url (when present) or the short link reaches the same code.

  restgetLinkQr

• shorten_url changes data auth-required never probed

  Create one HTTP or HTTPS short link. A registered account is required. Retry with the same idempotency_key.

  mcpshorten_url

• shorten_urls changes data auth-required never probed

  Create several short links in one call, matched by client_ref. Partial success is allowed. A registered account is required.

  mcpshorten_urls

• get_link reads auth-required never probed

  Fetch one owned link by id. A registered account is required. For a public status check, use resolve_short_url.

  mcpget_link

• resolve_short_url reads auth-required never probed

  Look up a 短.在线 code or short URL. Returns saved state, and the destination only when active. No account required. Does not look up other shorteners. Not a security verdict.

  mcpresolve_short_url

• create_qr reads auth-required never probed

  QR for an existing short link. Registered owner required. Does not create a link or fetch the destination. Encodes the ASCII short link with ?s=qr, same as GET /v1/links/{id}/qr. image_url is not an API key, OAuth token, or session.

  mcpcreate_qr

• update_link auth-required never probed

  Change the title or destination of a link you own. Requires links:update. Unverified email or an account under 7 days old can change the title only. Does not re-enable a link.

  mcpupdate_link

• disable_link auth-required never probed

  Disable a link you own: its short link and QR code stop redirecting. Requires links:disable and a verified email. Idempotent.

  mcpdisable_link

• createLinksBatch auth-required never probed

  Sync batch create. Body `items` length 1–100. Each item requires `client_ref` (unique within the batch) plus destination (`url` XOR `longUrl`) and optional `alias`. Partial success: HTTP 200 envelope with per-item `ok` + `result` (ActiveLinkCreated | NonActiveLinkCreated) or `ok: false` + `problem` + `retryable`. Correlate by `client_ref` only — never by array index. Over 100 items → 400 BATCH_TOO_LARGE (`/problems/batch-too-large`). Whole-batch `Idempotency-Key` required (scoped as `batch:{key}`). Same auth / abuse / destination safety rules as single create. Missing scope → **403** `INSUFFICIENT_SCOPE`. Accepted credentials are anonymous access, a session cookie, or an API key with `batches:create`. An OAuth access token is not accepted.

  restcreateLinksBatch

• listLinks auth-required never probed

  Returns short links owned by the authenticated account. Anonymous → **401**. Requires `links:read` on an API key, or a session cookie. An OAuth access token is not accepted on this route (401, not anonymous).

  restlistLinks

• getLinkStatus auth-required never probed

  Public status lookup by short code. No authentication required. States: active | quarantined | disabled | blocked | expired. Destination, short_url, and short_url_ascii omitted unless state is active. Unknown/deleted codes → 404 with problem type /problems/link-not-found. User-alias lookup folds case to lowercase; system short codes remain case-sensitive as stored. No credential is required. A presented API key must be valid and include `links:read` (otherwise 403). Any other presented Bearer, including an OAuth access token, is 401 and is not treated as anonymous.

  restgetLinkStatus

• updateLink auth-required never probed

  Update the title or destination of a link you own. API key scope `links:update`, or a session cookie. An OAuth access token is not accepted on this route. MCP update_link uses this handler. A destination change is screened again, needs a verified email and an account at least 7 days old, and is capped at 3 times per link and 20 times per account in any 24 hours. Disabled, quarantined, blocked, expired, and reported links cannot be changed. An update does not re-enable a link. Other users' / unowned → **404**.

  restupdateLink

• disableLink auth-required never probed

  Stop serving a link you own. API key scope `links:disable`, or a session cookie. An OAuth access token is not accepted on REST (401). Another account's link, or an unknown id, is 404. Email must be verified (403). A link that is quarantined, blocked, expired, or in an abuse posture is refused (403 LINK_BLOCKED). An already owner-disabled link succeeds and changes nothing. The same edit rate limit as PATCH applies (429). Idempotency-Key is not used. A form body or a cross-site Origin is rejected before auth (`csrf_rejected`, not problem+json). Responses are `Cache-Control: private, no-store`. Shlink must confirm before `link_disabled` is emitted; if confirm fails the response is 503 and a retry is queued. MCP `disable_link` uses the same logic with scope `links:disable`.
