Search GOV.UK's 700k+ content items using the official Search API.

Returns a list of matching content items with title, description, link, format, owning organisation(s), and last updated timestamp.

Use filter_format to narrow to specific content types (e.g. 'transaction' for citizen-facing services, 'guide' for guidance, 'publication' for official documents). Use filter_organisations to restrict to a department.

Find body sections in a GOV.UK content item matching a pattern.

Returns a list of {anchor, heading, snippet, match} hits — small per-section snippets centred on the match — so the LLM can decide which full sections to read via govuk_get_section.

Use this when answering content-based questions ("what does this guide say about X?", "find the bit about eligibility") rather than navigating by section number.

Pattern is regex; if it doesn't compile, falls back to literal substring.

List all UK government organisations registered on GOV.UK.

Returns a paginated list of organisations including their slug, acronym, type, and status. Use this to browse the full government structure or discover slugs for use with govuk_get_organisation or govuk_search filters.

Look up a UK postcode to retrieve its local authority, region, constituency, and other administrative geography.

Useful for determining which council area, parliamentary constituency, or NHS region a postcode falls within. Commonly used to direct users to the correct local service on GOV.UK (e.g. council tax, planning, waste).

Uses the postcodes.io public API (no key required).

Get metadata and navigable section index for a GOV.UK page.

Returns the page title, document type, publication dates, and a list of sections with their anchor IDs and headings. Use govuk_get_section to read the body of a specific section, or govuk_grep_content to search within the page body.

Get the HTML content of one named section of a GOV.UK page.

Use govuk_get_content first to get the list of available section anchors, then call this with the anchor of the section you want to read.

Get the profile of a UK government organisation by its slug.

Returns name, acronym, type, status, web URL, and parent/child organisations. Use govuk_list_organisations to browse all organisations and discover slugs.
