Dependency Mcp

Wraps six package registries (npm, PyPI, Maven, NuGet, RubyGems, Crates.io, and Go modules) into a unified dependency lookup interface. Exposes six tools split between single and batch operations: check latest versions, verify specific version existence, or pull full package metadata including all available versions. The batch endpoints handle up to 100 packages concurrently with built-in rate limiting and timeout protection. Useful when you're auditing dependencies across polyglot projects, validating lockfile versions in CI pipelines, or checking for updates without jumping between registry websites. Runs via npx so there's no global install required.
