The publisher's own server: A.X.E.L Filing
Remote MCP server for UK company tax work: Companies House lookups, CT600 corporation tax maths, filing deadlines and penalties, and Self Assessment estimates.
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/trade.axel%2Ffiling-public/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.

}READ THIS FIRST. How to prepare a CT600 with this server: which companies qualify, the order to gather figures in, what the words mean (micro-entity, filleted accounts, the declaration), and which cases to refer to an accountant instead. Takes no arguments.
Takes no parameters.
Look up a UK company at Companies House by company number: name, status, registered office, next accounts period, and a quick fit check.
companyNumberrequiredCheck whether a company fits this tool (micro-entity limits, single UK trade, no groups/R&D/gains/property). An overdrawn director loan is supported: the return carries a CT600A. Money in POUNDS.

Use with lookup_uk_company, which gives the accounts deadline. Dates are ISO (YYYY-MM-DD); filedOn defaults to today.
filedOnunpaidTaxct600DeadlineaccountsDeadlineaccountsLateLastYearct600ThirdLateInARowEstimate one person's UK Self Assessment for one tax year (2025-26 or 2026-27): income tax on salary, dividends, self-employment and interest, Class 4, student loans, payments on account, and Class 1 National Insurance on a salary from the person's own company. Uses the same engine as A.X.E.L Filing's returns, which matches HMRC's own test cases. An estimate only: nothing is saved or filed. Never ask for a UTR or National Insurance number.
incomeregionrequiredpayrolltaxYearrequireddividendseligibilitypostgraduateLoanstudentLoanPlansoverStatePensionAgebecameDirectorDuringYearThe director's whole year in one view: the company's corporation tax AND the director's own Self Assessment, side by side. Give either filingId (a saved CT600 draft, signed in) or the company's figures, plus the director's salary per tax year and each dividend with the date it was PAID (dividends are taxed in the tax year paid, which may differ from the company's year). Returns the company's profit, tax and profit after tax, each personal tax year's Self Assessment, Class 1 National Insurance on the salary (employee and employer, paid through payroll, with the Employment Allowance where it applies), payments on account, every due date, and the combined total. For what-ifs, call once per scenario and compare them side by side; when a scenario changes the salary, pass figures with staffCosts adjusted (salary plus employer NI) so corporation tax reflects it (see the guide). With MORE THAN ONE company, ask about every company they draw from and pass `companies` (or, signed in, `useProfile: true` to start from their saved answers): the Self Assessment covers all of it once, associated companies share the corporation tax limits, connected companies share one Employment Allowance, and NI can add the pay together. The user decides; present options, not a recommendation. Never ask for a UTR or National Insurance number.

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.
Declare a GitHub repository with a README, or serve resource_documentation in the OAuth protected-resource metadata.
A hosted service is used under its provider's terms, so no license is expected here. This check is left out of the percentage.
