From the Gb Eli repository's README, as published. We do not edit it. Read it on GitHub

gb-eli-mcp

An MCP server for legislation.gov.uk, The National Archives' official portal for United Kingdom legislation. It searches and retrieves Acts of Parliament, UK Statutory Instruments, and the equivalent instruments of the Scottish Parliament, Senedd Cymru/Welsh Parliament and Northern Ireland Assembly, with persistent identifiers and verifiable citations.

Part of the MateMatic eu-legal-mcp production line: the UK counterpart of the Polish sejm-eli-mcp and the German de-eli-mcp, built on the same architecture and citation contract against the UK's own source.

No native ELI. legislation.gov.uk does not publish a native /eli/ namespace

(confirmed live: GET /eli/ukpga/2018/12 returns 404), even though its own

persistent-identifier scheme predates and is closely related to ELI - the UK is widely

credited with pioneering the URI-based legislation-identifier concept that ELI later

formalised EU-wide. eli_uri therefore carries the UK's own stable id URI

(https://www.legislation.gov.uk/id/{type}/{year}/{number}) instead of a fabricated

ELI path - the same disclosure pattern used by this factory's nl-eli-mcp and

se-eli-mcp. See CONSTITUTION.md Art. 4.

Licence. Content is published under the Open Government Licence v3.0

(confirmed live from the site's own /help page), which permits copying, publishing

and adapting with attribution. This connector only relays that public content, with a

source_url on every response.

The eight tools

GOV.UK coverage (added v0.3.0, feature-003)

One upstream, many institutions: gbsearchgovuk filters by documenttype. Live-verified totals (2026-07-07, from the Search API's own total/facet fields - probe: https://www.gov.uk/api/search.json?count=0&facetcontentstoredocument_type=1000):

See SOURCES.md for the full per-source ledger, including what was scouted and deliberately rejected (ICO, FCA, IAC) and why.

Every response carries the contract: eliuri (e.g. https://www.legislation.gov.uk/id/ukpga/2018/12), humanreadablecitation (e.g. Data Protection Act 2018 c. 12), and sourceurl. Case-law responses carry the same-spirit contract (humanreadablecitation, sourceurl, datasetnote) - see CONSTITUTION.md Art. 5.
