Ask with this source

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

  • Package versions

    Use deps.dev (Open Source Insights) (depsdev) from fastCRW Pergamon, capability "Package versions" (package). You need the full version history of a dependency across an ecosystem. Example options: system=npm, name=express. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "depsdev" and capability "package". 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>

  • Version detail

    Use deps.dev (Open Source Insights) (depsdev) from fastCRW Pergamon, capability "Version detail" (version). You are checking whether one specific version of a dependency is licensed and advisory-free. Example options: system=npm, name=express, version=4.18.2. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "depsdev" and capability "version". 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>
