Overview

AI-generated overview

Lets an assistant look up UK company records, Gazette notices, sanctions screening, LEIs and UK legislation through a hosted endpoint.

What you can do
This remote MCP server exposes UK business and compliance data to an assistant. According to its registry description it covers Companies House records, Gazette notices, sanctions screening, LEIs and UK legislation. No individual tools are listed in the manifest, so the exact operations are not documented here.
When to use it
Worth adding when an assistant needs UK company or compliance lookups, such as checking a company's registration details, screening against sanctions, resolving an LEI, or consulting UK legislation. Less useful for non-UK or non-corporate research.
Requirements
A remote streamable HTTP endpoint at the provider's site; nothing to install locally. No authentication is required, but an optional X-API-Key header, obtained as a free key from the provider, raises the free allowance from 100 to 500 calls per day. Network access is needed.
Before you install
The optional X-API-Key header is a secret and should be kept out of logs and shared configurations. Queries go to a third-party service, so lookups are visible to that provider. The manifest lists no tools, so verify what the server can read or change before relying on it.

Installation

In SourceWeft

  1. Open UK company & compliance data 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/si.fourzerotwo%2Fuk-business/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

Other MCP clients

Add this to your client's mcpServers config.
