Struct StreamServerBuilder 

pub struct StreamServerBuilder { /* private fields */ }

Builder for creating Streamable HTTP MCP servers

Implementations

impl StreamServerBuilder

pub fn new(backend: BackendConfig) -> Self

Create a new builder with the given backend configuration

pub fn stateful(self, enabled: bool) -> Self

Set whether to enable stateful mode

pub fn mcp_id(self, id: impl Into<String>) -> Self

Set the MCP service identifier

pub fn tool_filter(self, filter: ToolFilter) -> Self

Set the tool filter configuration

pub fn backend_isolation(self, isolation: BackendIsolation) -> Self

Override backend isolation (URL defaults to per-session, stdio to shared).

pub fn max_sessions(self, max: usize) -> Self

Limit concurrent upstream sessions.

pub fn connect_timeout(self, timeout: Duration) -> Self

Timeout for per-session lazy backend connect.

pub async fn build(self) -> Result<(Router, CancellationToken, ProxyHandler)>

Build the server and return an axum Router, CancellationToken, and a management ProxyHandler.

For Shared isolation the returned handler is the live shared backend. For PerSession isolation it is a disconnected stub (real backends live inside each session’s handler); do not rely on swap_backend / availability APIs.
