The UK national open-data catalogue: search tens of thousands of public-sector datasets and read their metadata, resources and licences.
GET /v1/data/datagovuk/catalog-dcat1Request
One-based page of 100 datasets; the unfiltered catalogue runs to page 595, reported as hydra:lastPage. Pages average 0.4-2.5 MB but page 2 is 17.9 MB and is rejected by our 8 MB cap - narrow the result set with q, fq or modified_since rather than retrying it.
Solr query that narrows which datasets are paged over, so you can harvest a subject slice instead of all 595 pages. The hydra node then reports the reduced page count.
Exact-value filter applied before paging, typically to harvest a single publisher's DCAT records, e.g. organization:environment-agency. Also shrinks the page count the hydra node reports.

"@value": "These maps have been produced to meet SEPA’s duty to publish flood hazard maps as set out in the Flood Risk Management (Scotland) Act 2009. The maps show where there is a risk of flooding from the sea, from rivers and from surface water.The following probabilities are available for river flooding: - High - 10 year return period - Medium - 200 year return period - Low - 1000 year return period and 200 year return period plus climate change using the UKCP09 high emissions scenario for the 2080s.The river hazard maps show (where available): - Flood extent - Flood depth - Flood velocities where appropriate. The climate change scenario has been defined by United Kingdom Climate Projection 2009 (UKCP09) predictions for 2080 high emissions 95%ile predictions. Velocity is presented, where appropriate; this is determined by considering the confidence in input data, modelling method and impact. It is currently represented as one of four bandsMedium and low probability flood events were selected for consistency with return periods used in Scottish Planning Policy, whereas the high probability was chosen as it is reflective of observed events experienced over the last few decades."

Ask with this source
A prompt for your agent that names this source and how to call it through the crw MCP.
DCAT catalogue page
Use data.gov.uk (datagovuk) from fastCRW Pergamon, capability "DCAT catalogue page" (catalog-dcat). You are harvesting data.gov.uk as DCAT/RDF rather than reading single datasets - narrow with q, fq or modified_since first, because an unfiltered walk hits a page that exceeds our size cap. Example options: page=1, q=flood, fq=organization:environment-agency. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "datagovuk" and capability "catalog-dcat". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
Dataset detail
Use data.gov.uk (datagovuk) from fastCRW Pergamon, capability "Dataset detail" (dataset). You already have a data.gov.uk dataset slug or UUID and need its metadata or the download links for its files. Example options: id=road-accidents-safety-data. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "datagovuk" and capability "dataset". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
Dataset as DCAT JSON-LD
Use data.gov.uk (datagovuk) from fastCRW Pergamon, capability "Dataset as DCAT JSON-LD" (dataset-dcat). You need this dataset in a standards-based RDF shape to merge with other DCAT catalogues, rather than CKAN's own field names. Example options: id=road-accidents-safety-data. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "datagovuk" and capability "dataset-dcat". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
Search datasets
Use data.gov.uk (datagovuk) from fastCRW Pergamon, capability "Search datasets" (datasets). You are looking for UK government data on a topic and do not yet know which dataset or publisher has it. Example options: q=road safety, fq=organization:department-for-transport, rows=50. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "datagovuk" and capability "datasets". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
