mcp-kafka

A Model Context Protocol (MCP) server for performing Kafka client operations from AI assistants.

Overview

mcp-kafka provides a bridge between AI assistants and Apache Kafka, allowing them to interact with Kafka clusters through the Model Context Protocol. This tool enables AI assistants to create, manage, and interact with Kafka topics and messages directly.

Here is a short video demo on youtube

Features

The mcp-kafka server provides the following Kafka operations:

• Create Topic: Create a new Kafka topic with configurable partitions and replication factor
• List Topics: Get a list of all available Kafka topics in the cluster
• Delete Topic: Remove an existing Kafka topic
• Describe Topic: Get detailed information about a specific topic, including partition details
• Produce Message: Send messages to a Kafka topic with support for message keys and headers
• Consume Messages: Read messages from a Kafka topic with configurable timeout

Installation

Prerequisites

• Go 1.24 or higher
• A running Kafka cluster (default connection: localhost:9092)

Building from Source

1. Clone the repository:

   git clone https://github.com/kanapuli/mcp-kafka.git
   cd mcp-kafka
   

2. Build the application:

   make build
   

3. Optionally, build for a specific platform:

   make build GOOS=darwin GOARCH=arm64
   

Installing as a Claude Desktop Tool

To use mcp-kafka with Claude Desktop:

1. Build the application as mentioned above.

2. Place the executable in a location included in your system PATH or in a dedicated tools directory.

3. Please follow this Claude Desktop Tool Installation Guide to install the tool.

The JSON to be added to the claude_desktop_config.json file is as follows, Use the right username and password for SASL login. Leave them empty for PLAINTEXT authentication.

{
  "mcpServers": {
    "kafka": {
	    "command": "/Your-mcp-kafka-executable-path/mcp-kafka-darwin-arm64",
      "args": [
          "--bootstrap-servers=localhost:9092",
          "--consumer-group-id=mcp-kafka-consumer-group",
          "--username=",
          "--password="
        ],
      "env": {}
    }
  }
}

Configuration

The mcp-kafka tool accepts the following configuration parameters:

Parameter	Description	Default
topic	Topic to interact with	(required)
num_partitions	Number of partitions for topic creation	(optional)
replication_factor	Replication factor for topic creation	(optional)
produce_message_key	Key for produced messages	(optional)
produce_message_value	Value for produced messages	(optional)
produce_message_headers	Headers for produced messages	(optional)
consumer_timeout	Timeout in seconds for message consumption	10

These parameters will be automatically derived from your Natural language message to the LLM.

CLI flags for the mcp-kafka tool

The following flags should be used to configure the Kafka client:

--bootstrap-servers=localhost:9092
--consumer-group-id=mcp-kafka-consumer-group
