Twitch MCP Server

I got inspired to build this because of the following blog post

by Max Rydahl Andersen: https://quarkus.io/blog/mcp-server/.

I had written a Twitch Chat integration before, so decided to combine that knowledge with a Quarkus based MCP server as

described by Max.

This project is described in a bit more detail on my blog: https://tomcools.be/post/2025-jan-twitch-chat-mcp/

Building the MCP Server

This application is currently not pushed to Maven Central, so you need to build it locally and install it in your .m2

folder using `mvn install`.

Next we need a way to start the JAR file. In the examples below you'll see I

used JBang.

Running the MCP server

With MCP Inspector

Run `npx @modelcontextprotocol/inspector` to start a local inspector service.

• Create an MCP configuration to run the following

-

arguments: `["--quiet", "-Dtwitch.channel=YOUR_CHANNEL_NAME", "-Dtwitch.auth=YOUR_API_KEY", "be.tomcools:twitch-mcp:1.0.0-SNAPSHOT:runner"]`

Now you can manually call the tools.

With Claude Desktop

For Claude in claude_desktop_config.json

{
  "mcpServers": {
    "twitch-mcp-tomcools": {
      "command": "jbang",
      "args": [
        "--quiet",
        "-Dtwitch.channel=YOUR_CHANNEL_NAME",
        "-Dtwitch.auth=YOUR_API_KEY",
        "be.tomcools:twitch-mcp:1.0.0-SNAPSHOT:runner"
      ]
    }
  }
}

After restart, the tool should appear in your Claude UI.
