Overview

AI-generated overview

A remote MCP server for an inheritance tax calculator that compares an estate under current rules with the April 2027 pension-inclusion rules, and can hand off.

What you can do
Describe the calculator's inputs, units, ranges, defaults, outputs and underlying assumptions and tables, then run the calculation comparing the estate today (pension excluded) with the estate from April 2027 (pension included), using documented defaults for missing inputs. Read what the enquiry step does, who receives the details, the consent wording and how the person confirms, and list every enquiry field with its key, label, type, required flag, help text and allowed options. Submit an enquiry keyed by field key with consent, which validates the answers and returns a summary, the consent line and a confirmation token.
When to use it
Use it when someone wants an indicative inheritance tax comparison between current rules and the April 2027 pension-inclusion rules, or wants to start a free enquiry with human providers who quote directly. It is not a purchase or a guaranteed quote.
Requirements
A remote streamable HTTP endpoint; no package, environment variable or header is declared, and no authentication is declared. Network access to the provider's site is needed.
Before you install
Submitting an enquiry sends the person's details to human providers, so show the summary and consent line and get confirmation before submitting with consent. Nothing is bought, ordered or paid and no quote is guaranteed, but the figures are calculator estimates based on documented assumptions, not tax advice.

Installation

In SourceWeft

  1. Open Site in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

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/uk.co.iht2027calculator%2Fsite/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.

Read the install guide the agent follows

enquiry_describe

What you get: an ENQUIRY with a human (not a purchase, not a guaranteed quote)

Read first. States plainly what submit_enquiry does on IHT 2027 Calculator: it starts an enquiry with human providers who quote directly. Nothing is bought, ordered or paid; no quote is guaranteed; it is free. Also returns who receives the details, the consent wording, and how the person confirms.

Takes no parameters.

enquiry_fields

The questions the enquiry asks

Every field of the IHT 2027 Calculator enquiry: key, label, type, whether required, help text and the allowed options where there are any. Pass answers to submit_enquiry keyed by field key.

Takes no parameters.

submit_enquiry

Submit an ENQUIRY to human providers (two steps; not a purchase)

Submits an enquiry to IHT 2027 Calculator — NOT a purchase, NOT a guaranteed quote. Step 1: call with the answers (keyed by field key from enquiry_fields) and consent=true; it validates and returns a summary, the consent line and a confirmation token — show the person the summary and the consent line. Step 2: only if the person agrees, call again with the same answers, consent=true and the confirmation token; the enquiry is then submitted, and the person receives an email with a link they must click before any provider sees it. Consent means the person has read and agreed to: "Send my contact details to up to three accountancy and tax firms, chosen by IHT 2027 Calculator, who'll contact me directly. I'll be emailed each firm's name as my details go to it, and can stop any more firms getting them."
