Ask with this source

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

  • Enumerated values

    Use ClinicalTrials.gov (clinicaltrials) from fastCRW Pergamon, capability "Enumerated values" (enums). You need the valid values for a status, phase, study type or sponsor class filter. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "clinicaltrials" and capability "enums". 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>

  • Field size statistics

    Use ClinicalTrials.gov (clinicaltrials) from fastCRW Pergamon, capability "Field size statistics" (fieldsizes). You want to know how many conditions, locations or interventions a typical study carries. Example options: fields=Condition. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "clinicaltrials" and capability "fieldsizes". 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>

  • Field value statistics

    Use ClinicalTrials.gov (clinicaltrials) from fastCRW Pergamon, capability "Field value statistics" (fieldvalues). You want to know what values a field actually takes, and how common each one is, before filtering on it. Example options: fields=Phase, types=ENUM. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "clinicaltrials" and capability "fieldvalues". 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>

  • Data model metadata

    Use ClinicalTrials.gov (clinicaltrials) from fastCRW Pergamon, capability "Data model metadata" (metadata). You need the exact field names to pass to `fields` or to build an advanced filter. Example options: includeIndexedOnly=false. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "clinicaltrials" and capability "metadata". 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>
