The server builds `/changes/affecting/{item}/affected/{counterpart}`, and legislation.gov.uk only answers the affected-first order. ### Steps to reproduce 1. `uklaw_get_amendments` `{"item":"ukpga/2025/18","direction":"affecting","counterpart":"ukpga/2018/12"}` ### Actual behavior `filter_refused`:… [Read the thread](https://github.com/cyanheads/uk-legislation-mcp-server/issues/14) · 2026-09-26 · closed · 2 comments ### bug(uklaw_get_amendments): draft ISBN items always fail with filter_refused ### Server version 0.1.0 ### mcp-ts-core version 0.13.8 ### Description `uklaw_get_amendments` sends draft instruments (`ukdsi`, `sdsi`, `nidsr`, numbered by ISBN) to legislation.gov.uk's changes feed. The feed doesn't index draft types at all, so every such call fails with `filter_refused`. The recovery hint points at checking the item, but the item is valid: `/ukdsi/2026/9780348287233/data.xml` returns 200. ### Steps to reproduce 1. `uklaw_get_amendments`… [Read the thread](https://github.com/cyanheads/uk-legislation-mcp-server/issues/13) · 2026-09-26 · closed · 2 comments ### feat(uklaw_get_amendments): lower the default limit; a default page runs ~120 KB ### Use case `uklaw_get_amendments` defaults to `limit` 50. For a heavily amended Act, one default page is large: `{ "item": "ukpga/2018/12" }` returns 119,257 B (about 30k tokens), and `limit` 100 on `ukpga/1955/19` returns 232,461 B. A caller that takes the default spends a large share of its context on the first page before it knows whether it needs more. ### Proposed behavior Lower the default `limit` to 20 and keep the maximum. The cursor and the truncation disclosure already let a… [Read the thread](https://github.com/cyanheads/uk-legislation-mcp-server/issues/12) · 2026-09-26 · closed · 2 comments ### feat(uklaw_track_changes): show read progress in item-log mode on older windows ### Use case In item-log mode, `uklaw_track_changes` reads an item's Publication Log newest-first. For a heavily amended Act and a window months back, each call returns 0 events with `has_more: true` and an empty `days[]`, so the caller can't tell how far back the read has reached or how many calls remain. Repro: `{ "start_date": "2025-06-01", "end_date": "2025-06-30", "item": "ukpga/2018/12" }` took 3 calls (12 requests, pages 1–12 of a 1,330-event log) and returned no events. ### Proposed… [Read the thread](https://github.com/cyanheads/uk-legislation-mcp-server/issues/11) · 2026-09-26 · open · 2 comments ### bug(uklaw_track_changes): day walk spends its request budget on future days ### Server version 0.1.0 ### mcp-ts-core version 0.13.8 ### Runtime Node.js ### Runtime version Node 26.5.0 ### Transport HTTP (Streamable HTTP) ### Description The `uklaw_track_changes` day walk starts at `end_date` even when that date is in the future, so it spends its four-request budget on days that can't have events. A window that ends in the future returns nothing with `has_more: true`, and the notice blames the filters. A window entirely in the future costs 8 empty calls to… [Read the thread](https://github.com/cyanheads/uk-legislation-mcp-server/issues/10) · 2026-09-26 · closed · 2 comments ### bug(uklaw_get_amendments): provision-scan continuation page says nothing matched ### Server version 0.1.0 ### mcp-ts-core version 0.13.8 ### Runtime Node.js ### Runtime version Node 26.5.0 ### Transport HTTP (Streamable HTTP) ### Description When a provision scan spans several calls, a continuation page with no further matches gets the full-scan zero-hit notice. That notice says no effect references the provision, which contradicts matches already returned on earlier pages. The early-stop fragment also says "Only the first N…" on continuation pages.

The query did match; only the page is out of range, so the widening advice sends the caller to change a filter that is not the problem. ### Steps to reproduce 1. `uklaw_search_legislation`… [Read the thread](https://github.com/cyanheads/uk-legislation-mcp-server/issues/7) · 2026-09-26 · closed · 2 comments ## Most recent ### feat(uklaw_lookup_citation): read common citation forms that miss or come back ambiguous ### Use case `uklaw_lookup_citation` misses several forms that UK legal writing uses routinely, or returns them as ambiguous. For a title miss, the guidance sends the caller to `uklaw_search_legislation` `title`, which also returns 0 for these inputs. Its zero-hit notice then sends the caller back to `uklaw_lookup_citation`. | Input | Result now | Resolves to | | --- | --- | --- | | `section 45 of the Data Protection Act 2018` | miss (whole string read as a title) | `ukpga/2018/12`,… [Read the thread](https://github.com/cyanheads/uk-legislation-mcp-server/issues/6) · 2026-09-26 · closed · 2 comments ### bug(uklaw_get_document): dated read of an unrevised instrument reports the provision missing ### Server version 0.1.0 ### mcp-ts-core version 0.13.8 ### Runtime Node.js ### Runtime version Node 26.5.0 ### Transport HTTP (Streamable HTTP) ### Description legislation.gov.uk holds only the made text of an unrevised instrument, so any dated read 404s. The tool reports that 404 as `provision_not_found` or `version_not_found`. A caller asking for the text in force on a date after the instrument was made is told the provision had no text then, when the made text is the answer. ###… [Read the thread](https://github.com/cyanheads/uk-legislation-mcp-server/issues/5) · 2026-09-26 · closed · 2 comments ### bug(uklaw_get_document): outline chars understate read size; outlines carry 24 KB of effects ### Server version 0.1.0 ### mcp-ts-core version 0.13.8 ### Runtime Node.js ### Runtime version Node 26.5.0 ### Transport HTTP (Streamable HTTP) ### Description The outline `chars` value and the 40,000-character budget count text and annotation text but not the annotation citation lists, so a provision the outline reports as fitting renders to about twice that. Item-level outlines, which are the smaller read, also carry 20 full effect records, about 24 KB.

The result is a window that ends before it starts, or one that contradicts the same text read at another date. ### Steps to reproduce 1.… [Read the thread](https://github.com/cyanheads/uk-legislation-mcp-server/issues/3) · 2026-09-26 · closed · 2 comments ### bug(uklaw_get_amendments): pre-1963 regnal item paths always fail with filter_refused ### Server version 0.1.0 ### mcp-ts-core version 0.13.8 ### Runtime Node.js ### Runtime version Node 26.5.0 ### Transport HTTP (Streamable HTTP) ### Description `uklaw_get_amendments` fails with `filter_refused` for every pre-1963 Act addressed by its regnal path, which is the form `uklaw_lookup_citation` returns and the form effect records carry in `affected.item`. The calendar-year path of the same Act returns its effects, so the recovery hint (check the item with… [Read the thread](https://github.com/cyanheads/uk-legislation-mcp-server/issues/2) · 2026-09-26 · closed · 2 comments ### feat(uklaw_get_document): complete per-provision unapplied effects from the table of contents ### Use case A `uklaw_get_document` provision read lists only the unapplied effects legislation.gov.uk attaches to that fragment: those whose affected URI nests under the fragment's `IdURI`, plus item-wide `FoundRef` effects. Effects on an enclosing Part, Chapter or cross-heading never appear on a section read (`s. 65 heading` attaches to `part/3/chapter/4/crossheading/general-obligations`, not `section/65`), and a `part/3` read omits its sections' effects.
