Add MCP server for better integration with LLM clients

[nocnokneo]

Problem description

MCP tools to implement listing packages, adding packages, etc, would make things like Copilot Agent Mode more effective for Pixi-based projects

See: https://github.com/modelcontextprotocol

Interesting idea, do you know about tools like Pixi that already implement this?

There's oddly not much, but MCP is quite new.

One example is https://github.com/pinkpixel-dev/npm-helper-mcp

Another (very meta) example is: https://github.com/pathintegral-institute/mcpm.sh

uv has an open issue for it, but no action taken: astral-sh/uv#12500
