Licence: Macrostrat states its licence in every response envelope ("license": "CC-BY 4.0") and spells it out at /api/v2/meta: "All data are licensed under Creative Commons BY 4.0 International". The same metadata block asks for citation of the platform paper: "Peters, S.E. et al. Macrostrat: a platform for geological data integration and deep-time research. https://macrostrat.org".

Ask with this source

A prompt for your agent that names this source and how to call it through the crw MCP.

  • Stratigraphic columns near a point

    Use Macrostrat (macrostrat) from fastCRW Pergamon, capability "Stratigraphic columns near a point" (columns). You want the measured stratigraphic sections at a place rather than the individual rock units. Example options: lat=40, lng=-105, col_id=498. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "macrostrat" and capability "columns". 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>

  • Geologic map units at a point

    Use Macrostrat (macrostrat) from fastCRW Pergamon, capability "Geologic map units at a point" (geologic-map-units). You need the surface geology at a point - what the bedrock or sediment is mapped as - rather than a stratigraphic column. Example options: lat=40, lng=-105. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "macrostrat" and capability "geologic-map-units". 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>

  • Paleogeographic reconstruction

    Use Macrostrat (macrostrat) from fastCRW Pergamon, capability "Paleogeographic reconstruction" (paleogeography). You need to know where the continents and oceans were at a point in deep time. Example options: age=300. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "macrostrat" and capability "paleogeography". 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>

  • Stratigraphic sections near a point

    Use Macrostrat (macrostrat) from fastCRW Pergamon, capability "Stratigraphic sections near a point" (sections). You are assembling a stratigraphic column and need its constituent sections and age boundaries. Example options: lat=40, lng=-105. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "macrostrat" and capability "sections". 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>
