Hey @computerworxdev, thanks for reporting this! There are a couple of things going on here, let me walk through them.

Update showing the wrong command

We found a bug where the update notification was showing the Homebrew upgrade command even for npm installations. This happens because on macOS, the HOMEBREW_PREFIX environment variable is set system-wide whenever Homebrew is installed - so our detection was incorrectly assuming Homebrew for everyone on a Mac with Homebrew. We've fixed this so path-based detection takes priority now, which should correctly identify your npm install. This will be coming out in the upcoming release tomorrow (1.23.1).

Can't fully uninstall

After running npm uninstall -g @nanocollective/nanocoder, if nanocoder --version still works, it's almost certainly your shell caching the old binary path. Try either:

1. Restart your terminal, or
2. Run hash -r to clear the shell's path cache

If it still shows up after that, you might have a second installation somewhere. Run which nanocoder to see where it's pointing and that'll tell you how to remove it.

MCP fetch error

The @modelcontextprotocol/server-fetch error is coming from your MCP configuration (.mcp.json), not from Nanocoder itself. That npm package doesn't exist - the fetch MCP server is a Python package. You can either:

• Use the remote fetch server (no install needed): set the URL to https://remote.mcpservers.org/fetch/mcp with http transport
• Or use the local Python version: set the command to uvx with args ["mcp-server-fetch"] (requires uv installed)

You can reconfigure it by running /mcp inside Nanocoder and selecting the Fetch template.

Hope this helps get you sorted! Let us know if you run into anything else and I can continue to help :)

Thanks for reply
❯ which nanocoder
/usr/local/bin/nanocoder

mcp was working without any errors before , however it started throwing errors after 1.22.5 update. Perhaps mcp config become obsolete . Anyway I can remove that to to start fresh.

that's a great news that fixes are coming. I would like to start fresh and uninstall any references to current nanocoder version.

Please help to remove all files related to nano code and I will wait for a new version.

We could also all benefit for a complete removal and documentation instruction.

Please advise based on the prompt result on how to completely uninstall it
Thanks
