What the code does

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs a command on install [пакет] package.json:1
postinstall: node scripts/install.js
  const install = spawnSync(process.execPath, [installer], { stdio: "inherit" });
In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Checks whether it runs in a sandbox src/cli.rs:117
    if std::path::Path::new("/.dockerenv").exists()
Touches key and credential files .github/actions/setup-rust-kache/action.yml:121
        credentials_file="$HOME/.aws/credentials"

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 16 min ago.

run in your terminal

This one needs environment variables set before it will start: TAILSCALE_API_KEY (Tailscale API key.), TAILSCALE_RMCP_VERSION (Optional GitHub release tag override for the downloaded Tailscale RMCP binary.), TAILSCALE_RMCP_REPO (Optional GitHub owner/repo override for release asset downloads.), TAILSCALE_RMCP_RELEASE_BASE_URL (Optional release download base URL override.), RUST_LOG (Tracing filter for Tailscale RMCP logs.). The author declared them in the registry entry; get the values from the project itself.

Tailscale RMCP — questions

Answers built from our own checks of this server.

Is Tailscale RMCP working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 3 of 91 checks got a reply (3.3%), average response time 350 ms. The bar chart above shows every period we have measured.
The registry lists Tailscale RMCP as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Tailscale RMCP?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Tailscale RMCP need an API key?
No. Tailscale RMCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.
How fast is Tailscale RMCP?
It answers our handshake in 350 ms on average, which is faster than 47% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Tailscale RMCP?
The npm package @dinglebear/rtailscale was installed 46 times in the last week. Week over week that is +41%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Tailscale RMCP open source?
Yes — it is published under the MIT licence, written in Rust, 5 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
