Summary
If your agent needs to know whether upgrading from Anthropic SDK 0.25 to 0.30 will break its code, this saves you from burning tokens on GitHub scraping. It tracks 18 SDKs that AI tooling depends on (Anthropic, OpenAI, LangChain, MCP, Mistral, Vercel AI, and others) and pre-classifies breaking changes so you can call check_version with your current version or pull get_recent_breaking to see what changed across the ecosystem in the last 30 days. The four tools (list_tracked, get_package, get_recent_breaking, check_version) replace what would otherwise be 5 to 15 seconds of release feed parsing with a sub-100ms lookup.

What it does
Tracks latest version + breaking changes for SDKs AI agents depend on (Anthropic, OpenAI, Google GenAI, MCP SDK, LangChain, LlamaIndex, Mistral, Cohere, Vercel AI, Next.js, React, HuggingFace, Replicate, Ollama).
Your agent can:
list_tracked— packages we track + latest version + 30d breaking-change countget_package— full record with recent breaking events + GitHub release URLget_recent_breaking— breaking changes across all packages, filterablecheck_version— "I'm on v X — am I behind, and what breaks if I upgrade?"
