About mycrab-mcp

mycrab-mcp is an MCP server that gives AI agents access to mycrab.space tunnels for public HTTPS URLs through Cloudflare Tunnels. Its tools cover free temporary tunnels and paid reservations for permanent subdomains.

Key features

  1. 01Check subdomain availability
  2. 02Get a command for a free tunnel
  3. 03Reserve a permanent subdomain with SOL
  4. 04Fetch SKILL.md documentation

Use cases

  1. 01Create a temporary public HTTPS address for an agent
  2. 02Check whether a desired subdomain is available
  3. 03Reserve a custom subdomain through the x402 flow

MCP support

The MCP server exposes tools for checking domains, setting up free tunnels, buying subdomains with SOL, and retrieving skill documentation. The README shows configuration for Claude Desktop.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "isgudtek-mycrab": {
      "command": "uvx",
      "args": [
        "mycrab-mcp"
      ]
    }
  }
}
Run commanduvx mycrab-mcp

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

check_domain("mybot")

# Free throwaway tunnel — live in <60 seconds
setup_free_tunnel()
# → "curl -s https://mycrab.space/agent-setup-auto.sh | bash"

# Permanent custom subdomain (autonomous x402 flow)

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
