Support Streamable HTTP MCP Servers (e.g. Smithery)

Seems like this can be closed now, @ashwin-ant?
I didn't see anything in the changelog but I saw this today:

Usage: claude mcp add [options] <name> <commandOrUrl> [args...]

Add a server

Options:
  -s, --scope <scope>          Configuration scope (local, user, or project) (default: "local")
  -t, --transport <transport>  Transport type (stdio, sse, http) (default: "stdio")
  -e, --env <env...>           Set environment variables (e.g. -e KEY=value)
  -H, --header <header...>     Set HTTP headers for SSE transport (e.g. -H "X-Api-Key: abc123" -H "X-Custom: value")
  -h, --help                   Display help for command

And --transport http seems to work properly. 🙂

"Set HTTP headers for SSE transport" description shouldn't be SSE only, as it is used for HTTP as well.

Also https://docs.anthropic.com/en/docs/claude-code/mcp doesn't have it documented yet

Thanks for the catch! Yes, that line should also say HTTP.
