Struct ServerConfig 

pub struct ServerConfig {
    pub bind_address: SocketAddr,
    pub mcp_path: String,
    pub enable_cors: bool,
    pub max_body_size: usize,
    pub enable_get_sse: bool,
    pub enable_post_sse: bool,
    pub session_expiry_minutes: u64,
    pub allow_unauthenticated_ping: bool,
}

Configuration for the HTTP MCP server

Fields

bind_address: SocketAddr

Address to bind to

mcp_path: String

Path for MCP endpoint

enable_cors: bool

Enable CORS

max_body_size: usize

Maximum request body size

enable_get_sse: bool

Enable GET SSE support (persistent event streams)

enable_post_sse: bool

Enable POST SSE support (streaming tool call responses) - disabled by default for compatibility

session_expiry_minutes: u64

Session expiry time in minutes (default: 30 minutes)

allow_unauthenticated_ping: bool

Allow ping requests without Mcp-Session-Id header (default: true)

When true, the server accepts pre-initialization ping requests without requiring a session. The full middleware stack still runs with session=None, so rate-limiting middleware can still block unauthenticated pings.

Set to false for hardened deployments that require session for all methods.
