Ask with this source
A prompt for your agent that names this source and how to call it through the crw MCP.
Advanced company search
Use Companies House (companieshouse) from fastCRW Pergamon, capability "Advanced company search" (advanced-search). You need every company matching structured criteria rather than one name, e.g. all active companies in a SIC code. Example options: company_name_includes=tesco, company_status=active, company_type=plc. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "companieshouse" and capability "advanced-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>
Alphabetical company search
Use Companies House (companieshouse) from fastCRW Pergamon, capability "Alphabetical company search" (alphabetical-search). You are walking the register in name order rather than searching for one company. Example options: q=tesco, size=20. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "companieshouse" and capability "alphabetical-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>
Officer appointment detail
Use Companies House (companieshouse) from fastCRW Pergamon, capability "Officer appointment detail" (appointment). You have an appointment id from an officers list and want that single appointment. Example options: companyNumber=00445790, appointmentId=lnfNdAqKHBZCL2akA7SXLkkA8KI. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "companieshouse" and capability "appointment". 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>
Charge detail
Use Companies House (companieshouse) from fastCRW Pergamon, capability "Charge detail" (charge). You have a charge id from the charges list and need its particulars. Example options: companyNumber=00445790, chargeId=5QU1lSudRI2jTIfUv_AOVxfLxVE. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "companieshouse" and capability "charge". 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>
