Change8 MCP

Breaking Change Alerts for AI Agents

Know what broke before your code does.

❌ Without Change8

You upgrade a dependency and your code breaks. LLMs don't know:

❌ That pydantic v2 removed the .dict() method
❌ That langchain moved ChatOpenAI to a new package
❌ What migration steps you need to take

You waste hours debugging and searching through changelogs.

✅ With Change8

Change8 MCP gives AI agents instant access to structured breaking change data for hundreds of popular packages.

Example prompt:

I'm upgrading langchain from 0.1 to 0.2. What breaking changes should I know about?

Change8 responds with:

Breaking changes with exact details
Migration steps to fix your code
Affected symbols (functions, classes, modules)

No more searching through changelogs. No more surprise production failures.

Available Tools
