Tools have disappeared from this server

A tool that vanishes takes a piece of your agent with it, and the change arrives silently. Watch this server and every such change lands in your inbox.

Available tools 9

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

link
get_link
按 id 查询当前授权账号拥有的链接。需要已注册账号。公开状态查询用 resolve_short_url。 Fetch one owned link by id. A registered account is required. For a public status check, use resolve_short_url.
update_link
修改自有短链的标题或目标地址。需要 links:update。未验证邮箱或注册未满 7 天只能改标题。不会重新启用短链。 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.
shorten
shorten_url
为 HTTP 或 HTTPS 目标地址创建一条短链。需要已注册账号。重试必须复用相同的 idempotency_key。 Create one HTTP or HTTPS short link. A registered account is required. Retry with the same idempotency_key.
shorten_urls
按 client_ref 对应,一次创建多条短链,可部分成功。需已注册账号。 Create several short links in one call, matched by client_ref. Partial success is allowed. A registered account is required.
begin
begin_registration
客户端无法启动 OAuth 时的后备入口。返回浏览器注册链接。不创建账号,不接收密码,也不代用户同意条款。 Fallback when the client cannot start OAuth. Returns a browser registration link. Does not create an account, accept a password, or accept terms.
create
create_qr
为已有短链返回二维码。需已注册的所有者。不新建短链,不抓取目标地址。编码带 ?s=qr 的 ASCII 短链,与 GET /v1/links/{id}/qr 相同。image_url 不是 API 密钥、OAuth 令牌或会话。 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.
disable
disable_link
停用你拥有的短链,停用后短链和二维码将停止跳转。需要 links:disable 与已验证邮箱。幂等。 Disable a link you own: its short link and QR code stop redirecting. Requires links:disable and a verified email. Idempotent.
links
get_links
列出当前账号拥有的短链。cursor 与 limit 同 GET /v1/links。需要 links:read。 List links this account owns. cursor and limit match GET /v1/links. Requires links:read.
resolve
resolve_short_url
查询本站短码或本站短链的已保存状态;仅 active 时返回目标地址。无需账号。不查询其他短链服务;结果不是安全结论。 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.

短.在线 — questions

Answers built from our own checks of this server.

What can 短.在线 do?
It exposes 9 tools, read directly from the server on our last check. Among them: begin_registration, create_qr, disable_link, get_link, get_links, resolve_short_url and 3 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is 短.在线 mostly used for?
Its tools cluster around link and shorten. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is 短.在线 working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 427 ms. The bar chart above shows every period we have measured.
Did 短.在线 ever remove tools?
Yes. create_account, get_link_analytics are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect 短.在线?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does 短.在线 need an API key?
No. 短.在线 completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is 短.在线?
It answers our handshake in 427 ms on average, which is faster than 30% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
