check_domainLABSCO SUMMARY
A public URL for something local, now.
It closes the gap between having something running on localhost and needing to show it to a service that only speaks to the public internet — with the throwaway case free and time-boxed.
What it is
A front door to mycrab.space, which hands out public HTTPS URLs through Cloudflare Tunnels. A free tunnel gets an automatic subdomain that expires on its own; a permanent subdomain is reserved by paying in SOL on Solana mainnet.
What you get
- A subdomain checked for availability on mycrab.space
- The command for a free tunnel with an automatic subdomain, live in under a minute
- A permanent subdomain reserved after payment, returning a setup token and command
- The full SKILL.md fetched — templates, commands and the advanced usage
Requirements
uvx to run it. A free tunnel needs nothing else; a permanent subdomain is paid for in SOL on Solana mainnet, with the transaction signature passed to the reservation call.
Setup effort
One command — uvx mycrab-mcp
USE CASES
01
Exposing a local server so a webhook can reach it
The free tunnel comes back as a command to run, with an automatic subdomain that expires on its own — no cleanup and no account.
02
Claiming a permanent name for a project
Check the subdomain is free first, then reserve it with the Solana transaction signature; the reply carries the setup token and command.
03
Getting the setup right the first time
The full documentation is fetched into the session, so the tunnel command is run with the right template rather than guessed at.
