Gov Uk Content MCP server

@pipeworx/gov-uk-content

GOV.UK Content API MCP — the rendered content + metadata behind every page on gov.uk. Keyless.

Part of Pipeworx — an MCP gateway connecting AI agents to 1679+ live data sources.

Tools

• content(base_path) — content for a gov.uk page (e.g. /jobsearch, /government/organisations/cabinet-office)
• search(query, count?, start?, filter_format?) — full GOV.UK search
• organisations(start?, count?) — list organisations (departments, agencies, …)
• taxons(base_path?) — taxonomy tree node
• search_autocomplete(query) — autocomplete on the search index

Data sources

• Content API: https://www.gov.uk/api/content/
• Search API: https://www.gov.uk/api/search.json

UK departmental manuals (fleet #1972)

Topic-level discovery over the largest body of official interpretation on GOV.UK. All of it was reachable before only if you already knew the base_path of the page you wanted — which is the one thing a caller asking a tax question does not know.

Measured 2026-09-14 against www.gov.uk/api/search.json:

• hmrcmanuals(query?, includeotherdepartments?, count?, start?) — which manuals exist, with their basepaths.
• hmrcmanualsearch(query, manual?, includeotherdepartments?, count?, start?) — a UK tax question in plain words → the sections that answer it, each with sectionid, publishedat, age_days. manual accepts either "employment-income-manual" or the full /hmrc-internal-manuals/employment-income-manual.
• hmrcmanualsection(basepath | manual + sectionid, maxchars?) — one section's full text, with withdrawn, firstpublishedat, publishedat, age_days.
• hmrcmanualchanges(manual, since?, sectionid?, limit?) — HMRC's own per-section revision log, newest first**.

The freshness trap, written down because it returns a clean 200

A manual's details.changenotes[] is a complete revision history served oldest first — 1,025 entries for the Employment Income Manual, running 2016-08-02 to 2026-09-11. Reading changenotes[0] as "the latest change" reports a ten-year-old edit as today's news, with no error anywhere. hmrcmanualchanges sorts explicitly by published_at descending rather than reversing, so a change in upstream ordering cannot silently invert the answer.

A section's own publicupdatedat is the reliable per-section date and is what every tool here returns as sourcelastmodified. Note it does not equal the section's first change note: EIM42776 has a change note published 2016-08-02 and a publicupdatedat of 2022-06-27.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "gov-uk-content": {
      "url": "https://gateway.pipeworx.io/gov-uk-content/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/gov-uk-content/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — askpipeworx, discovertools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.
