Built to solve the time-blind agent problem: LLMs trained on frozen data emit deprecated package code 70-90% of the time. This server gives Claude a single MCP tool, check_dependency_freshness, that queries npm and PyPI registries plus GitHub releases to return the latest version, release dates, deprecation flags, versions-behind count, and a dated breaking-change diff since your current version. Every field includes source citations and access dates. Works over Apify's hosted MCP endpoint at mcp.apify.com, the Actor's own /mcp Streamable-HTTP path, or local stdio. Priced pay-per-event at $0.005 per package checked. Requires an Apify token. No scraping, just public registry APIs, so no ToS risk.
