Enum McpTransportKind 

pub enum McpTransportKind {
    Stdio,
    Http,
    Sse,
    Auto,
}

How to reach an MCP server.

• stdio — spawn a local process (default when command is set)
• http — Streamable HTTP (spec 2025-03-26+); preferred remote transport
• sse — legacy HTTP+SSE (spec 2024-11-05)
• auto — for URL endpoints: try Streamable HTTP, fall back to legacy SSE

Variants

Stdio

Http

Streamable HTTP (single MCP endpoint, POST/GET + optional SSE)

Sse

Legacy dual-endpoint HTTP+SSE transport

Auto

Probe Streamable HTTP first, then fall back to legacy SSE
