Build an MCP Server with Java

Jul 2025, 15. by Sergio del Amo

This session shows how to build an MCP (Model Context Protocol) Server in Java.

We first discuss how to build an MCP Server with Java without any framework, and then compare what frameworks (Spring Boot, Micronaut, and Quarkus) offer.

We will implement an MCP Server with each framework. The MCP Server will expose custom tools that can be accessed by MCP clients.

You will learn how to test your implementation using the MCP Inspector tool and connect to your MCP server with Claude as a client.

Target Audience

Developers interested in creating an MCP (Model Context Protocol) Server in Java.

Elevator Pitch

MCP allows you to expose reusable tools and resources to build agentic microservices. Doing this takes us beyond basic LLM chatbots to dynamic, problem-solving systems that deliver real value in real professional settings. In this session, you will learn how to build your first MCP Server.

Git commit Hash in Gradle build file

Mar 2025, 26. by Sergio del Amo

The following snippet shows how to get the Git commit hash in a Gradle build file using the Gradle Kotlin DSL.

fun String.execute(): String {
    val process = ProcessBuilder(*this.split(" ").toTypedArray())
        .directory(project.rootDir)
        .redirectErrorStream(true)
        .start()
    return process.inputStream.bufferedReader().readText().trim()
}
val commitHash = "git rev-parse --verify HEAD".execute()

Use a Shortcut To Create a New Text File In a Folder On a Mac

There is no command in the Finder that will let you create a new blank file at your current location. But you can create a Shortcut that will let you do this each time easily. The Shortcut needs to use both JavaScript and shell scripting to get the job done.

Enable the local calendar in Fantastical for Mac

Jan 2025, 28. by Sergio del Amo Permalink

I found a way to enable this thanks to a Reddit post.

Fantastical for Mac needs and extra step to enable the local calendar. I’ll copy and paste what they told (it’s working for me).

  • Copy the following line: x-fantastical3://defaults?key=EventKitSyncAll&value=1&type=bool&group=1
  • Open your web browser
  • Paste the text into the URL field and press enter
  • Allow Fantastical to open
  • Confirm the alert that appears
  • Quit Fantastical completely (Click Fantastical in the menu bar and choose "Quit Fantastical Completely") then open the app again.
