## Caveats and sources

Each one names the column it qualifies and cites the page it comes from, which is often not the page in the row's primary source.

### Legacy HTTP+SSE

Zed documents a local server and a remote server, taking a command or a URL. SSE isn't mentioned either way.

### Custom headers

Headers suppress OAuth, and Zed documents it as intended behavior: when a remote server has no configured `Authorization` header, Zed prompts you to authenticate through the OAuth flow. This is the inverse of Cursor's bug.

### Pre-registered client ID

No configuration field exists for one, so a server that requires a hand-registered client can't be configured.
