Ask with this source

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

  • Package collaborators

    Use npm Registry (npm) from fastCRW Pergamon, capability "Package collaborators" (collaborators). You want to know who can publish an unscoped package - its current owners rather than its historical authors. Example options: package=express. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "npm" and capability "collaborators". 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>

  • Scoped package collaborators

    Use npm Registry (npm) from fastCRW Pergamon, capability "Scoped package collaborators" (collaborators-scoped). You want to know who can publish a scoped package like @babel/core. Example options: scope=babel, package=core. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "npm" and capability "collaborators-scoped". 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>

  • Package dist-tags

    Use npm Registry (npm) from fastCRW Pergamon, capability "Package dist-tags" (dist-tags). You only need to know which version a tag like latest or next currently points at. Example options: package=express. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "npm" and capability "dist-tags". 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>

  • Scoped package dist-tags

    Use npm Registry (npm) from fastCRW Pergamon, capability "Scoped package dist-tags" (dist-tags-scoped). You need the current version behind a tag for a scoped package like @babel/core. Example options: scope=babel, package=core. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "npm" and capability "dist-tags-scoped". 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>
