What is the Mycrab MCP MCP server?

Most cloud and infrastructure work still happens through a UI a human drives. Mycrab MCP MCP server moves it into the conversation instead. MCP server for mycrab.space — instant public HTTPS URLs via Cloudflare Tunnels for AI agents.

The tools it exposes

The server publishes 4 tools. What each one is for:

  • check_domain — Check if a subdomain is available on mycrab.space
  • setup_free_tunnel — Get the command for a free tunnel (auto subdomain, expires 61 min)
  • buy_domain_sol — Reserve a permanent subdomain after paying 0.05 SOL on Solana mainnet
  • get_skill_docs — Fetch the full SKILL.md — all templates, commands, and advanced usage

Getting it running

The server ships on PyPI as mycrab-mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

How it compares

This sits in the cloud and infrastructure group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Mycrab MCP's toolset — check_domain, setup_free_tunnel, buy_domain_sol and 1 more — is a fair guide to whether it matches your workflow. It is maintained by isgudtek; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
