Struct InitializeReply 

pub struct InitializeReply {
    pub mcp_session_id: String,
    pub result: InitializeResult,
}

The successful Initialize payload — the upstream’s verbatim InitializeResult plus the native Mcp-Session-Id the CLI got back from dialing the actual MCP server. The API forwards both to the proxy: the result as the JSON-RPC body, the session id as the Mcp-Session-Id response header. The CLI is a pure medium — it doesn’t synthesize capabilities, doesn’t name itself, doesn’t pin a protocol version. Whatever the upstream MCP advertised is what the proxy sees.

Fields

mcp_session_id: String

Upstream’s native Mcp-Session-Id. One per CLI-hosted MCP server — no aggregation, no encoding.

result: InitializeResult

The upstream’s verbatim InitializeResult (capabilities, server info, protocol version). Returned as-is to the proxy.
