alt Hacker NewsThe "CLI crowd" is also primarily using LLMs on their own computer. Where they have their CLI tools.
This doesn't cover the case when you're talking to an LLM from web, or via Slack or Linear, etc. There, you will want MCP so the LLM can use services on your behalf as you. That's portability.
Why can’t the LLM you’re talking to on the web have access to your CLI tools?
When you talk to an LLM on the web, the harnesses spin up a fresh environment (I would hope it’s a VM…) so that the LLM can do stuff like run arbitrary Python and Bash scripts to complete the task you asked it for.
There’s no reason why you shouldn’t be able to customize this environment to add whatever CLI tools and credentials you need for the agent to act on your behalf.
The UX would be exactly the same.
