FAQ from Tailscale MCP Server

What is MCP?

MCP stands for Model Context Protocol. It's a protocol that allows applications to interact with LLMs by providing them with tools and prompts.

Is this server secure?

The server is designed to be read-only, but it's important to be aware of the potential risks involved in exposing any part of your network to third-party applications, especially when interacting with LLMs.

What Tailscale commands are considered safe?

The list of safe subcommands includes: netcheck, ip, dns status, status, metrics, ping <peer>, version, exit-node list, and whois <ip>.

The server is not appearing in Claude Desktop, what should I do?

Check that the path to the binary in your configuration is correct, verify Tailscale CLI is installed and accessible in your $PATH, and check Claude Desktop logs for errors.

What if I get command errors?

Try running the command directly using the Tailscale CLI to verify it works, check that your Tailscale is correctly configured and connected, and ensure the command is in the allowed safe list.
