Rust 中的 MCP 工具: 减少安装摩擦

• Node.js has npx & bunx
• Python has uvx, pipx

Both ecosystems support downloading + installing + running MCP servers.

Most Python projects still specify pip, and only a few suggest first installing uv, then using uvx. Node.js npx and bunx are the easiest — but both often run into problems with outdated NodeJS runtimes in environments like VSCode extension hosts. Trying to debug that? High friction.

What About Rust?

I’ve always found cargo quite novel — Rust is one of the few languages with its own packaging system. I realize they are separate, but also at this point quite inseparable. In this case, MCP is still new, and perhaps there’s opportunity to enhance cargo. That’s the discussion I’d like to start. I think the best approach for Rust is probably to build on top of pkgx, though several options scratch the itch in different ways — none of them fully support the MCP use case yet.
