Enum Response 

pub enum Response {
    McpBuffered {
        envelope: Envelope,
        message: McpMessage,
        status: StatusCode,
        headers: HeaderMap,
    },
    McpStreamed {
        envelope: Envelope,
        body: Body,
        status: StatusCode,
        headers: HeaderMap,
    },
    OauthJson {
        doc: Value,
        status: StatusCode,
        headers: HeaderMap,
    },
    Raw {
        body: Body,
        status: StatusCode,
        headers: HeaderMap,
    },
    Upstream502 {
        reason: String,
    },
}

Sum type produced by the transport, or by a short-circuiting middleware. impl IntoResponse for Response (below) converts this into an axum response at the edge.

Variants

McpBuffered

Buffered MCP response: one parsed McpMessage, mutated in place by response middlewares, serialized once by EnvelopeSeal.

Fields

envelope: Envelope

message: McpMessage

status: StatusCode

headers: HeaderMap

McpStreamed

Streamed MCP response: bytes forwarded as-is. Content-touching middlewares do not fire on this variant.

Fields

envelope: Envelope

body: Body

status: StatusCode

headers: HeaderMap

OauthJson

OAuth discovery / token JSON — a parsed document that UrlMapMiddleware rewrites before IntoResponse.

Fields

doc: Value

status: StatusCode

headers: HeaderMap

Raw

Forwarded raw body — no inspection.

Fields

body: Body

status: StatusCode

headers: HeaderMap

Upstream502

Upstream failure. Travels through the response chain like any other response — HealthTrack records it, emit tags the event as upstream error, and IntoResponse renders a 502.

Fields

reason: String
