BumpGuard MCP server

Check which lines of your code break when you upgrade a library, and catch made-up API calls.

Developer tools Coding For it and development Developer Tools

BumpGuard is a small helper that your AI assistant can use to check your code before you upgrade a library. It tells you exactly which lines of your own code would break, with line numbers and fix hints. It is handy for anyone who writes Python, .NET, or Java code and leans on an AI assistant to help.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. It cannot look inside your project or check what is really installed on your computer. An MCP server is a small helper program that gives your AI a new skill. BumpGuard is that helper here: it reads the real libraries on your machine and answers questions about them, so your AI stops guessing.

What this MCP server does

You ask your AI something like whether upgrading pandas to 2.2 will break your code. Your AI passes the question and your code to BumpGuard. BumpGuard reads the library's real public list of functions and classes, compares the old version with the new one, and checks which of those changes touch your code. It then hands back a short list of findings with line numbers and suggestions. Your AI shows you that list in the chat.

Flow diagram: you ask your AI “Will upgrading pandas to 2.2 break my code?”, on your own computer the BumpGuard MCP server works with your code and libraries, and you get back A short list of findings.

What you can do with it

Check if upgrading a library will break your code, with line numbers
See what changed between two versions of a library
Verify that the imports and calls in a snippet really exist
Check whether a package is installed, and get the closest real name if not
List the real public functions and classes of a package
Catch made-up or wrong API calls in AI-written code

Try asking your AI

“Before upgrading pandas to 2.2, check whether my data pipeline breaks.”
“Verify this snippet actually uses the installed OpenAI SDK.”
“List the real methods on httpx.Client.”
“What changed between pydantic 1.10.13 and 2.0.3?”

What it gives back to you

You get back a short list of findings, each with the symbol, the line number in your code, how serious it is, and a fix hint. You also get a small summary with counts, like how many breaking changes were found. If nothing is proven to break, it says so plainly. Everything appears as text in your chat.

Before you start

What you need

Python 3.10 or newer
BumpGuard installed in the same environment as the project you are working on
An MCP-compatible client, like Claude Desktop, Claude Code, Cursor, Windsurf, or VS Code with Copilot
For .NET checks: the .NET SDK installed

Good to know

BumpGuard uses static analysis, so a clean result means nothing was proven to break, not that everything is safe.

Install it with your AI

Add BumpGuard MCP server to your AI, no technical skills needed

You don't install anything by hand. You copy one prompt, paste it into an AI that can work on your computer, and it checks, installs and connects the server for you, asking you when it needs something.

Sign in to get the install prompt

Members get a ready-made prompt that lets the Claude desktop app check BumpGuard MCP server, install it and connect it for them, step by step. You don't need any technical skills: you copy, paste and answer a few questions. Your connected AI can also find and install any of the 4,066 MCP servers here for you.
