閱讀 https://sourceweft.com/mcp/io.usefulapi%2Foksign/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。把它新增到你客戶端的 mcpServers 設定中。

Pro covers this server only. Subscribe with oksign_upgrade (it returns a Stripe Checkout link). Cancel any time with oksign_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running oksign_upgrade before then undoes the cancel.

signed_docid必填Get a document's form descriptor
The form descriptor of an uploaded document: its signature and form fields (type, page, position, signer, required, signing options) and the signing URL of each signer. The URLs let their holders sign, so share them only with the signer. GET /v1/formdesc/retrieve.
docid必填Find the source or signed copy of a document
Given a source_docid, the signed_docid of its signed copy (absent if not signed yet) and the timestamp; given a signed_docid, the source_docid. An empty result means the document never existed here or was removed. GET /v1/linkedlist/retrieve.
