Show HN: Gomcptest – A Go toolkit for testing LLM agents (MCP) with VertexAI

I built a Go toolkit that helps test and interact with Model-Calling-Protocol (MCP) tools, primarily for developing and understanding agentic systems. It currently works with Google's VertexAI SDK.

What it does:

- Provides a basic set of tools for testing MCP implementations

- Includes a CLI that emulates Claude Code functionality

- Offers an OpenAI API v1 compatible server (with some limitations)

Try it yourself:

1. Clone the repo: `git clone https://github.com/owulveryck/gomcptest`

2. You'll need a Google Cloud Platform account with VertexAI API enabled

3. Follow the setup instructions in the README

This is strictly a proof of concept for learning purposes - I built it to better understand how agentic systems work and to have a simple way to develop and test various tools.

I'm especially interested in feedback on:

- Any use case you think it can enable

- Ideas for additional tools that would be
