Overview

AI-generated overview

MCP server for mycrab.space that lets an assistant check subdomain availability, get free Cloudflare Tunnel setup commands, and reserve paid subdomains.

What you can do
  • Check whether a subdomain is available on mycrab.space
  • Get the setup command for a free auto-assigned tunnel that expires after 61 minutes
  • Reserve a permanent subdomain after a 0.05 SOL payment on Solana mainnet
  • Fetch the full SKILL.md with templates, commands and advanced usage
When to use it
Useful when an assistant needs to expose a local service or agent at a public HTTPS URL quickly, or when you want to claim a permanent custom subdomain on mycrab.space without leaving the chat.
Requirements
Runs locally as a Python package launched with uvx (Python/uv tooling). No authentication, environment variables or headers are declared. A Solana wallet and mainnet transaction are needed for the paid permanent subdomain option; network access to mycrab.space is required.
Before you install
The paid option involves spending 0.05 SOL on Solana mainnet and passing a transaction signature to the server, so verify the amount and recipient before paying. The free tunnel is temporary (about 61 minutes) and the returned setup command is meant to be run in a shell, which executes remote script content. Public URLs expose whatever the tunnel points to.

Installation

In SourceWeft

  1. Open mycrab-mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Score

40% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
