## 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

Documented for legacy MCP servers, configured by pointing the same `url` field at an `/sse` path.

### Custom headers

The MCP page names no header, `Authorization`, OAuth, or bearer token. A `headers` field is real but documented on a different JetBrains page, for the Codex agent. Don't read JetBrains Air's documentation onto this row: that's a different product, and its documentation does cover headers and an OAuth flow.
