mycrab-mcp

isgudtek/mycrab-mcp

Wraps mycrab.space's Cloudflare Tunnel service so AI agents can spin up public HTTPS endpoints on demand. Exposes four tools: check if a subdomain is available, generate a free 61-minute tunnel with auto-assigned domain, reserve a permanent custom subdomain by submitting a Solana transaction signature (0.05 SOL on mainnet), and pull the full skill documentation. The free tunnel flow returns a curl command that sets everything up in under a minute. Reach for this when your agent needs to expose a local service for webhooks, demos, or temporary integrations without manual ngrok wrangling or DNS configuration.
