把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。
閱讀 https://sourceweft.com/mcp/io.usefulapi%2Fwefile/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。

}Use your WeFile account from Claude, Cursor, or any MCP client. It lists companies and filings, creates and saves CT600 drafts, generates documents, and submits filings to HMRC and Companies House. Hosted, no local install: connect with your own credentials.
Live endpoint: https://wefile.usefulapi.io/mcp · Homepage: https://usefulapi.io
https://wefile.usefulapi.io/mcp.claude mcp add --transport http wefile https://wefile.usefulapi.io/mcp, then run /mcp to log in.Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your WeFile credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/wefile/
On first connect you provide your WeFile API key (in the WeFile developer dashboard under API Access; it needs the Developer Package). The server validates it and stores it per user. No keys go in config files.
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this server only. Subscribe with wefile_upgrade (it returns a Stripe Checkout link). Cancel any time with wefile_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running wefile_upgrade before then undoes the cancel. Or write to [email protected].

List companies
List the companies in your WeFile workspace, with their WeFile company id, name, Companies House number and filing count. Start here to find the companyId for other tools. WeFile API: GET /companies.
pagelimitsearchstatusGet accounting periods
Get the accounting reference date and the accounting periods of one company, with the filed flags and due dates from HMRC and Companies House. Uses Companies House data. WeFile API: GET /company/periods.
companyId必填Add company
Add a UK company to your WeFile workspace by its 8-character Companies House number. WeFile fills in the name and address from Companies House. WeFile API: POST /company/add.
companyNumber必填List filings
List the filings in your WeFile workspace: CT600 returns and Companies House accounts, with their status. WeFile API: GET /filings.
pagelimitsearchstatusGet filing status
Get the overall status of a filing and its submission history. WeFile polls HMRC and Companies House first, so the result shows the latest accept or reject. Use it after wefile_submit_filing. WeFile API: GET /filing/status.
filingId必填List submissions
List the submissions made for a filing to HMRC and Companies House, with their status, HMRC IRmark and body hash. Does not poll the agencies; use wefile_get_filing_status for that. WeFile API: GET /filing/submissions.
filingId必填List documents
List the documents WeFile can generate for a filing (accounts, tax computation, CT600), with whether each is available now. WeFile stores no documents; generate them with wefile_generate_document. WeFile API: GET /filing/document/list.
filingId必填Generate document
Generate one filing document from the saved filing data. PDFs come back as base64 text and iXBRL as HTML. Results over 200,000 characters are cut and marked truncated. Filings over 12 months need subPeriod 1 or 2. WeFile API: GET /filing/document/generate.
type必填filingId必填subPeriodCreate filing
Create a draft CT600 and Companies House filing for one company and accounting period. Nothing is sent to HMRC or Companies House yet. For an amendment of a WeFile filing, set isAmendment and amendmentOfFilingId. For an amendment of a return filed elsewhere, set isAmendment only: the draft starts empty. WeFile API: POST /filing/create.
companyId必填isDormant必填periodEnd必填isAmendmentperiodStart必填directorNamecharityStatusnumberOfEmployeesamendmentOfFilingIdassociatedCompaniesincludePnlInAccountsSave filing
Save the figures and settings of a draft filing. Set profitLossData and balanceSheetData from the figures the user gives; WeFile computes the totals and the tax. Status in_progress starts the payment step. Send the gateway password and the Companies House code only to wefile_submit_filing. Required: filingTypes, before submit. WeFile API: POST /filing/save.

Remove the stored HMRC gateway id, gateway password and Companies House code from a filing. Other fields stay. Refused while a submission is in flight. WeFile API: POST /filing/credentials/delete.
filingId必填Submit filing
Send a filing to HMRC, Companies House or both. A live key (wf_live_) files a real return, so confirm the figures first; try a test key (wf_test_) before a live one. Pass the gateway credentials here for this call only: WeFile uses them once and does not store them. Check the result with wefile_get_filing_status. WeFile API: POST /filing/submit.
