How to Make an MCP Server in Go

ladislav@prskavec.net (Prskavec.Net) — Fri, 12 Jun 2026 09:00:00 +0000

Most developers use AI models, but few extend them. In this talk we go a level deeper and build our own Model Context Protocol (MCP) server in Go, using an AI assistant (Claude, Augment, Gemini) to write the code. You can use any language, but I think AI is especially good at Go, and I explain why.

MCP is an emerging standard that lets AI systems securely reach tools, APIs, and real-world data. I show how to build a small, working MCP service, connect it to an AI client, and expose your own capabilities, from querying observability data to automating workflows. By the end we extend our own coding agent with an MCP server so it can do more for us.

From Small Terraform Projects to Terralith

ladislav@prskavec.net (Prskavec.Net) — Wed, 23 Apr 2025 18:00:00 +0000

In this talk, I’ll walk you through the common evolution of Terraform projects - from simple beginnings to complex, sprawling infrastructure definitions that become increasingly difficult to manage. We’ll explore the familiar challenges many teams face: starting with a handful of resources that gradually expand into an unwieldy codebase as business requirements grow. I’ll share our team’s journey transitioning from this state to Terralith, creating a more scalable and modular infrastructure solution.

Bubble Tea - how to make better terminal UI

ladislav@prskavec.net (Prskavec.Net) — Tue, 23 Apr 2024 18:00:00 +0000

The fun, functional, and stateful way to build terminal apps. A Go framework based on The Elm Architecture. Bubble Tea is well-suited for simple and complex terminal applications, either inline, full-window or a mix of both.

Repository with demo - Simple RSS reader for Podcasts for show bubbletea library in action.

OpenTelemetry as best way how to instrument your CICD pipeline

ladislav@prskavec.net (Prskavec.Net) — Wed, 27 Sep 2023 18:00:00 +0000

OpenTelemetry as best way how to instrument your CICD pipeline. Talk cover observability CICD tools and show demo how instrument Github Action using Honeycomb buildevents and manual instrumentation in project using Dagger.io for pipelines.

How we run stateful services for customers in Kubernetes

ladislav@prskavec.net (Prskavec.Net) — Thu, 11 May 2023 18:00:00 +0000

Disclaimer: I work for Pure Storage, which provides and sells flash storage for enterprise customers. We have a PDS (Portworx Data Services) service that offers stateful services (PostgreSQL, Kafka, Cassandra, MongoDB, Consul, Mysql, Redis, Elasticsearch, Couchbase, RabbitMQ, ZooKeeper) with a single operator for the deployment of all these services. We have a few other operators for backup and operations. All are based on the Portworx Kubernetes storage solution, and PDS will work in a cloud or on-premise Kubernetes cluster.

CI pipelines should be code! Dagger Go SDK

ladislav@prskavec.net (Prskavec.Net) — Wed, 30 Nov 2022 18:00:00 +0000

Dagger is a programmable CI/CD engine that runs your pipelines in containers. Develop your CI/CD pipelines as code, in the same programming language as your application. Dagger executes your pipelines entirely as standard OCI containers. This has several benefits:

Instant local testing
Portability: the same pipeline can run on your local machine, a CI runner, a dedicated server, or any container hosting service.
Superior caching: every operation is cached by default, and caching works the same everywhere
Compatibility with the Docker ecosystem: if it runs in a container, you can add it to your pipeline
Cross-language instrumentation: teams can use each other’s tools without learning each other’s language

Getting started with fuzzing

ladislav@prskavec.net (Prskavec.Net) — Tue, 31 May 2022 18:00:00 +0000

What is fuzzing? Fuzzing is the art of automatic bug detection. Fuzzing aims to stress the application and cause unexpected behavior, resource leaks, or crashes. There are many types of fuzzing, and I will focus show us new possibilities that we get in Go 1.18 to use this tool to improve our code.

Compliance as Code

ladislav@prskavec.net (Prskavec.Net) — Thu, 23 Jan 2020 14:00:00 +0000

I went through classical audits, where you fill tens of excel sheets and then consult with internal audit what and how to improve etc. As SRE (Site Reliability Engineer) deals with monitoring and automation, there is also depriving people of manual work. I have seen how the problem is solved on a large scale (cloud providers). I have experience with Oracle Cloud Infrastructure (OCI) and Amazon Web Services (AWS). I’ll show you how to move from Excel to an automatic, near real-time compliance check solution. Proposed solution using Chef Inspec Framework.
