Kafka Schema Registry MCP server

Lets your AI look at and manage your Kafka schema registries, and move schemas between them.

Developer tools For it and development Data Platforms

This is a helper for people who work with Kafka and its Schema Registry. It connects your AI assistant to one or more registries so you can ask questions and make changes in plain language. It is handy if you deal with data schemas and want to stop clicking around in separate tools.

What is an MCP server? The 30-second version

On its own, your AI can only chat. An MCP server is a small helper program that gives your AI a new skill or a connection to another app. This one connects your AI to Kafka Schema Registry, so it can look up your schemas, check them, and register new ones for you when you ask. You set it up once, and then you just talk to your AI like usual.

What this MCP server does

You ask your AI something about your schemas, like what subjects exist or whether a change is safe. The AI sends that request to this helper program. The helper then talks to your Schema Registry over the network. It brings the answer back and the AI explains it to you in the chat. If you ask it to register or change something, it does that too, as long as you have allowed it.

Flow diagram: you ask your AI “Show me the subjects in my development registry”, the Kafka Schema Registry MCP server connects it to Schema Registry, and you get back your answer in plain chat.

What you can do with it

List all your schema registries and their subjects
Show the details and versions of any schema

Migrate schemas from one registry to another

Try asking your AI

“List all schema contexts in my production registry”
“Show me the subjects in the development context”
“Check if this new user schema is compatible with the current one”
“Register a new schema for user events with fields id, name, and email”

What it gives back to you

You get answers in plain chat: lists of registries, subjects, or contexts, the full text of a schema, or a yes or no on compatibility. When it registers or changes something, it tells you what it did. For exports, it can hand you a file or a block of text you can save.

Before you start

What you need

A running Kafka Schema Registry you can reach (a web address like http://localhost:8081)
Docker installed if you use the recommended setup, or Python if you run it locally
The Claude desktop app or another AI tool that supports MCP servers
Optional: a username and password if your registry requires login

Good to know

It can change or delete schemas and contexts, so turn on VIEWONLY mode or use a read-only account if you only want to look, and be careful in production.
