## MCP tools (3)

### `nl_wetten_search` (~164 tokens)

Search Dutch national legislation by title (the BWB Basiswettenbestand). Matches the cite-title and official/unofficial titles as a phrase and returns the regulation(s) in force on "as_of" (default today), with BWB ids (BWBR...) that nl_wetten_get_law and nl_wetten_get_article take. Title search only — does not search article full text.

Input parameters:

- `as_of` (string): Resolve matches to the version valid on this ISO date (YYYY-MM-DD). Defaults to today.
- `limit` (number): Max results to return, 1-50 (default 20).
- `query` (string, required): Title words to match, e.g. "Algemene wet bestuursrecht" or "Wetboek van Strafrecht". Dutch.

### `nl_wetten_get_law` (~199 tokens)

Look up one Dutch regulation by its BWB id (e.g. "BWBR0005537") as it stood on "as_of" (default today): citeertitel, authority, legal domain(s), the toestand's own validity period (separate from publication/in-force dates), its chapter structure, and a paged list of article numbers (offset/limit, has_more/next_offset — never truncated silently). Pass an article number to nl_wetten_get_article to read its text.

Input parameters:

- `as_of` (string): Resolve to the version valid on this ISO date (YYYY-MM-DD). Defaults to today.
- `bwb_id` (string, required): BWB identifier, e.g. "BWBR0005537".
- `limit` (number): Max article numbers to list, 1-300 (default 100).
- `offset` (number): 0-based offset into the article list (default 0).

### `nl_wetten_get_article` (~193 tokens)

Read the original Dutch text of one article/section of a Dutch regulation, by BWB id and article number (e.g. "1:3", as listed by nl_wetten_get_law), as it read on "as_of" (default today). Returns the full article text broken into its numbered "lid" (paragraph) subdivisions, the date that exact text took effect, and the toestand's validity period as separate fields. Pass an earlier as_of to read a past version of the same article.

Input parameters:

- `article` (string, required): Article number as it appears in the law, e.g. "1:3", "6:162", "5".
- `as_of` (string): Read the article as it stood on this ISO date (YYYY-MM-DD). Defaults to today.
- `bwb_id` (string, required): BWB identifier, e.g. "BWBR0005537".
