What this server can do
22 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
browse_transcriptions(lang, archive_code, archive_number)- Browse transcriptions hierarchically Returns a hierarchical browse of available page transcriptions. Mirrors `/transcripties/lijst/`. Three modes, depending on the supplied filters: * No filter — top-level list of source archives ordered by total transcription count (descending). * `archive_code` — list of all archive numbers (archieftoegangen) within that archive, ordered by archive number. * `archive_code` + `archive_number` — list of all inventories within that archive number, ordered by inventory number. The order of items is fixed and cannot be overridden. Results are always returned in full (no paging).
get_archives- List all archives with statistics Returns an array of all participating archives including their archive code (used in other API calls), name, homepage URL, Twitter handle, ISIL code and search URL on Open Archives. Note: version 1.1 adds ISIL codes and removes defunct ArchiefWiki links.
get_births(name, start, eventyear, eventplace, number_show, eventprovince)- Finds birth records Required: name.
get_births_years_ago(years, number_show)- List births that occurred a specified number of years ago Returns a list of birth records for people born exactly the specified number of years ago from today. Note: version 1.1 uses `archive_code` instead of `archive` and includes the archive name and record URL. Required: years.
get_breakdown(lang, sort, group_by, year_end, eventtype, min_count, eventplace, sourcetype, year_start, number_show, archive_code)- Cross-tabulation aggregation grouped by one dimension Returns record counts filtered by any combination of archive, source type, event type, event place and year range, grouped by ONE chosen dimension (archive, sourcetype, eventtype, place or year). Use this endpoint to answer questions such as "how many Bidprentjes per archive?" or "how many marriages per year in Amsterdam?". The response includes the total filtered record count, the total number of distinct groups (capped at 750) and the top-N groups according to the chosen sort. Required: group_by.
get_census_data(year, place, gg_uri, province, richness)- Dutch census data for a place and year Retrieves census data for a Dutch place or municipality for the census year nearest to the specified year. Available census years: 1795, 1830, 1840, 1849, 1859, 1869, 1879, 1889, 1899. Data sources: Volkstellingen.nl (DANS) and Gemeentegeschiedenis.nl. Either `place` or `gg_uri` must be provided. Required: year.
get_comment_stats(archive_code)- Comment count statistics Returns the total number of validated comments made on records. When no archive_code is provided, the global total is returned. When an archive code is provided, the count for that archive is returned. Note: version 1.1 uses `archive_code` instead of `archive`.
get_deaths(name, start, eventyear, eventplace, number_show)- Finds death records Required: name.
get_event_type_stats(archive_code)- Record count statistics per event type Returns statistics about event types. Without an archive_code all event types across the entire dataset are returned with total counts. With an archive_code, only event types for that archive are returned. Note: version 1.1 uses `archive_code` instead of `archive`.
get_family_name_stats(lang, eventtype, eventplace, number_show, eventyearend, eventyearstart)- Family name frequency statistics Returns the number of times family names appear in events for the selected source types, place and period. Results are ordered by frequency. Open Archives uses this endpoint to power its family name frequency visualisation.
get_first_name_stats(eventyear, eventplace, number_show)- First name frequency statistics for a given place and year Returns the top-X list of first names in the specified place and year. When a person has multiple forenames, only the first is counted. Currently only Amsterdam is available as a place. Required: eventplace, eventyear.
get_historical_weather(date, lang, latitude, longitude)- Historical weather measurements for a date and location Returns historical weather measurements from the nearest Dutch weather station for the specified date and coordinates. Data sources are the Royal Netherlands Meteorological Institute (KNMI): measurements 1701–1905 and 1901–2014. Note: this endpoint exposes several types of historical datasets, so measurement types and units can vary between records. Required: date, longitude, latitude.
get_marriages(name1, name2, start, eventyear, eventplace, number_show)- Finds marriage records of couples (bride or groom) Required: name1, name2.
get_profession_stats(lang, eventplace, number_show, eventyearend, eventyearstart)- Profession frequency statistics Returns the number of times professions appear in records for the selected period and place. Results are ordered by frequency. Open Archives uses this endpoint to power its profession frequency visualisation.
get_record_stats(archive_code)- Record count statistics per archive Returns record count statistics. When no archive is specified, all archives are listed with their total number of records. When an archive code is specified, the source types available for that archive are returned with their individual record counts. Note: version 1.1 uses `archive_code` instead of `archive`.
get_source_type_stats(archive_code)- Record count statistics per source type Returns statistics about source types. Without an archive_code all source types across the entire dataset are returned with total record counts. With an archive_code, only source types for that archive are returned. Note: version 1.1 uses `archive_code` instead of `archive`.
match_record(lang, name, birthyear)- Match a person to birth and death records Searches the genealogical dataset by exact name and birth year and returns the Open Archives URIs of birth records, death records and registrations in which the person is mentioned. Required: name, birthyear.
search_records(lang, name, sort, start, birthplace, eventplace, sourcetype, not_archive, number_show, archive_code, country_code, relationtype)- Search genealogical records Searches the genealogical dataset and returns found persons and records. Supports filtering by archive, source type, event place, birth place, relation type and country. Results are pageable and sortable. Note: version 1.1 uses `archive_code` instead of `archive`. Required: name.
search_transcriptions(q, lang, start, year_end, year_start, number_show, archive_code, archive_number, inventory_number)- Full-text search across page transcriptions Performs a full-text search across the page transcriptions of historical documents indexed by Open Archives. Mirrors the search UI at `/transcripties/zoek.php`. Results are ordered by Elasticsearch relevance (the order is fixed and cannot be overridden) and are returned paginated. Each match includes a source citation, page identifier and up to five highlighted text fragments. The set of facets returned depends on the supplied filters. Required: q.
show_record(lang, archive, identifier)- Show a single genealogical record Returns one specific genealogical record in JSON format (UTF-8). The response conforms to the Archive 2 All (A2A) model. Also available as XML, GEDCOM, Turtle (TTL) and N-Triples (NT) by changing the file extension in the URL. Note: version 1.1 features improved JSON/XML output and adds N-Triples and Turtle formats. Required: archive, identifier.
show_transcription(id, lang)- Retrieve a single transcription Returns the full transcript of a single page along with its source citation. Mirrors `/transcripties/toon/<id>`. AI-generated summaries are deliberately not returned by this endpoint. Required: id.
view_transcription(ids, highlight_term)- Open one or more transcribed document pages in an interactive deep-zoom viewer with the transcription text alongside. Pass page identifiers returned by search_transcriptions / browse_transcriptions (form <ISIL>_<archive>_<page>, e.g. NL-SdmGA_1504889_11). Optionally highlight a term in the transcript. Hosts without MCP Apps support receive a text summary plus inline preview images. Required: ids.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
| Signal | Value | What it measures | Window | Observed | Source |
|---|---|---|---|---|---|
| GitHub stars | 2 | Number of GitHub accounts that bookmarked this repository since it was created. It is a bookmark count, not installs, not active users and not quality. | cumulative, all time | GitHub | |
| Last commit | 2026-07-31 | Date of the most recent push to any branch. This is the strongest cheap indicator of whether the project is still maintained. | point in time | GitHub | |
| Open issues | 0 | Open issues plus open pull requests, as GitHub counts them together. A high number can mean an active project or an abandoned one. | as of fetch | GitHub | |
| Latest published version | 1.1.1 | Latest version string the maintainer published to the registry. | as of fetch | Model Context Protocol | |
| Registry record last updated | 2026-07-31 | When the registry record was last updated by its maintainer. | point in time | Model Context Protocol | |
| First listed in the MCP Registry | 2026-07-31 | Date this server was first published to the official MCP Registry. Not a usage or quality measure. | point in time | Model Context Protocol | |
| repository status | active | The repository exists on GitHub and is not archived. This says nothing about how recently it was worked on. | as of fetch | GitHub | |
| mcp tools declared | 22 tools | Number of functions the server itself declared when asked to list them. This is what the server offers an agent, not a measure of how well any of them work. | as of probe | mcp.openarchieven.nl | |
| mcp endpoint status | ok | The server listed 22 functions when asked. | as of probe | mcp.openarchieven.nl |
