Show HN: PackageLens MCP – search package registries across multiple ecosystems (github.com)

Search package registries across multiple ecosystems (npm, PyPI, RubyGems, Crates.io, Packagist, Hex) and fetch package context (README, downloads, GitHub info, usage snippets). It features smart ecosystem auto-detection, so your AI can find packages without needing to specify which ecosystem to search.
