Rustunnel MCP Server

If you already use Rustunnel, the rustunnel mcp server is the piece that lets your assistant work with it directly. Give AI agents public HTTPS/TCP/UDP URLs for any localhost service. Open source, self-hostable.

What the server does

The open-source tunnel that scales with you. Don't pay for idle time. Secure, Rust-fast, and Pay-as-you-go.

Installation

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

• Build — The Build tool exposed by this server
• Files — The Files tool exposed by this server
• Installation — Homebrew installs pre-built binaries — no Rust toolchain required. The formula is updated automatically on every release. This installs both

Credentials and setup notes

Configuration is passed through the environment: TEST_DATABASE_URL, YOUR_CLOUDFLARE_API_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Worth knowing first

• Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Rustunnel's toolset — Build, Files, Installation — is a fair guide to whether it matches your workflow. It is maintained by joaoh82; worth a glance at recent repository activity before you build anything load-bearing on it.
