install tangentstorm ai on mac m1

[Brian Schott]

Hi forum,

Could you please provide detailed instructions for installing the AI system in my j9.8 folder?

I currently have j-mcp-macos-arm64 in my downloads folder, but I am unsure where it should be moved. Additionally, I am not sure which file to use between j-mcp.mcpb and j-mcp.dxt, or where it should be located.

Could you also clarify which file needs to be made executable and if I should rename it with a .sh extension? When I previously attempted to change the extension, I received a prompt asking to confirm the change, so I want to ensure I am following the correct procedure.

Thanks,
Brian Schott

Hi Brian - I'm attempting the same thing on both a Mac M4 and a PC.  No joy so far but will let you know when I figure out anything.

I'm trying to do this as specified on the Github repo:

Install

Claude Desktop one-click

Grab j-mcp.mcpb (or j-mcp.dxt — same file, different extension for compatibility with older Claude Desktop builds) from the latest release, double-click it, and Claude Desktop will prompt you for your J install directory — the one that contains j.dll / libj.so / libj.dylib and profile.ijs. That's the whole install.

Not knowing what to do, I tried dropping the "manifest.json" into the Claude desktop; it seems to recognize what it is but clearly I'm missing something very basic.  On the PC, Claude tells me "The J programming language embedded as MCP tools..." and asks me what I want to do but I don't know.

I then installed Claude Code which gives me a terminal (command line) and had a little more luck but I still don't know how to tell Claude to ingest the j-mcp.mcpb file.

Hi Brian,

I don't know specifically on a Mac nor in what framework you're planning to use the server, nor do I have Claude that seems to be expected by the installation instructions in the J-MCP repo.

So, probably, the following is not going to help your case so much, but perhaps it's interesting for someone else...

 
I did get the J-MCP server to work with KIT (https://github.com/mark3labs/kit) using local Ollama models (Gemma4:26b) seems to work rather well, even locally on a laptop with only an iGPU (Using Vulkan).

For getting J-MCP to work with KIT, you'd have to copy the binary into the bin directory in the J installation, and configure a local MCP server by putting this in the configuration file (.kit.yml by default):
mcpServers:
  j-mcp:
    type: "local"
    command: "<path to J install>/bin/j-mcp-linux-x86_64"
    args: []
    enviroment:
      JPATH: "<path to J install>/bin/jconsole"
  

For those wanting to use Vulkan with Ollama on Linux, (e.g. unsupported GPU for NVidia Cuda or AMD ROCm), I found it works great even with a simple integrated GPU, giving a considerable speed-up compared with CPU-only. It requires some configuration of Ollama using sudo systemctl edit ollama, adding:

[Service]
Environment=HIP_VISIBLE_DEVICES=-1
Environment=OLLAMA_VULKAN=1
Environment=GGML_VK_VISIBLE_DEVICES=0
Environment=OLLAMA_IGPU_ENABLE=1

to the file. I found this online, and am not pretending I know what it all means. See https://docs.ollama.com/gpu#vulkan-gpu-support for more info (that page also has info on Apple systems).

Good luck,

Jan-Pieter

an mcp server "helps an agentic framework".  I recommend opencode for being open and mature, but also because it includes free capable models through their zen routing service.  Openrouter often has free models as well.  You can ask llm, pointing to the github and your download how to install it and use the mcp.  You probably need to restart opencode.   I used MiMo 2.5 (was free at the time).  Their BigPickle model is free, and would likely be the best choice, as it would be trained on opencode configuration.

Okay, I see that not only is the readme pretty confusing, but claude itself has changed since I made the mcp server.

I went ahead and just recorded setting it up for both claude desktop and claude code. 

This video is pretty much everything I was going to say in my segment of the meeting so maybe I'll reserve that for a

very quick recap and answering questions. (Though also happy to answer questions here)
