Create and save CT600 filings, generate documents, submit to HMRC and check status in WeFile.
The publisher's own server: Ably MCP by usefulapi
Hosted WeFile server that lets an assistant list UK companies and filings, draft and save CT600 returns, generate documents, and submit to HMRC and Companies…
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.usefulapi%2Fwefile/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}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.

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.

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.
companyIdrequiredAdd 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.
companyNumberrequiredList 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.
filingIdrequiredList 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.
filingIdrequiredList 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.
filingIdrequiredGenerate 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.
typerequiredfilingIdrequiredsubPeriodCreate 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.

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.
filingIdrequiredSubmit 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.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
