Universal · Bridgehead BY BRIDGEHEAD ↗

Any API key × Claude · ChatGPT

Any API key, right in your chat.
One connector for all of them.

Most AI services hand you an API key, and claude.ai, ChatGPT, the phone and voice can't take one: their MCP servers want the key in a header, or in a config file on your own computer. Universal · Bridge is one connector you add once: sign in, add a key for each service on your key page, and its tools are in your chat. Leonardo.ai is first; more join the same connector, and you add their keys whenever you want them.

Questions

Which services are in it?

Leonardo.ai today: images with Lucid Origin, Lucid Realism and Ideogram 3.0. More join over time; each appears on your key page, where you add its key when you want it.

Why can't I add Leonardo's own MCP server?

Its server wants your key in an API-Key header, and claude.ai and ChatGPT can't send one. Universal · Bridge keeps the key and sends it for you, so it works in any chat, on the phone and by voice.

Is my key safe?

Each key is checked, kept encrypted in Bridgehead's vault and used only to call that service for you. You pay each service directly; remove any key at universalbridge.fyi/key.
