Each reported crime includes its date/time, approximate location, crime type, and crime classification.\r\n\r\nNOTE: For the safety and security of victims of crimes, street address locations, other than reported street intersections or highway locations, are not exact. They are adjusted to the nearest block level.\r\n\r\nThere are two columns of city/town information. The first is the reported city/town name in the crime records. The second, which is not in the crime records, is a translation of it into the more commonly known city/town name, or into Marin County when it appears to be in an unincorporated area. For example, Almonte and Tam Valley are reported city/town names, but they are both in the more commonly known city of Mill Valley. Lucas Valley translates to San Rafael, etc. We hope that the translated city/town column will facilitate analysis.",

}Attribution: Source: data.marincounty.gov. Dataset attribution as stated by each publishing agency.
Licence: Datasets on this portal declare the licence "Open Data Commons Open Database License" in their Socrata metadata; the portal publishes no separate API licence and different datasets may carry different terms. Quoted as found in the portal's own catalogue.
Ask with this source
A prompt for your agent that names this source and how to call it through the crw MCP.
Catalogue search
Use data.marincounty.gov (data-marincounty-gov) from fastCRW Pergamon, capability "Catalogue search" (catalog-search). You want to find a dataset on this portal by keyword and do not know its four-by-four id. Example options: q=taxi, offset=0, order=page_views_total DESC. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "data-marincounty-gov" and capability "catalog-search". 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 metadata
Use data.marincounty.gov (data-marincounty-gov) from fastCRW Pergamon, capability "Dataset metadata" (dataset). You already hold a dataset id and need its columns, licence or description before querying rows. Example options: id=nnw4-58yt. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "data-marincounty-gov" 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 inventory
Use data.marincounty.gov (data-marincounty-gov) from fastCRW Pergamon, capability "Dataset inventory" (datasets). You need to enumerate what this portal publishes, or page through its newest datasets. Example options: offset=0, order=createdAt, category=Transportation. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "data-marincounty-gov" 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>
Row count
Use data.marincounty.gov (data-marincounty-gov) from fastCRW Pergamon, capability "Row count" (row-count). You need to know how large a dataset is before downloading it, or want a cheap liveness check. Example options: id=nnw4-58yt. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "data-marincounty-gov" and capability "row-count". 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>
