No lock-in
Don't like us? Swap the endpoint URL and walk.
Twinkle Hub is an MCP endpoint, not an SDK, not a framework, not a platform that wants you writing code against us. Plug in today, swap us out tomorrow — change the url in your client config and you're gone. MCP is open protocol; rolling your own or going elsewhere is always an option. What we offer is the curation, predictability, and daily refresh — judge that on its own merits.
