Struct ServerConfig 

pub struct ServerConfig {
    pub port: u16,
    pub stdio: bool,
    pub max_connections: usize,
    pub request_timeout_secs: u64,
}

Server configuration controlling network and connection settings

Security Implications

The server configuration affects the attack surface and resource consumption:

• Lower connection limits prevent resource exhaustion attacks
• Shorter timeouts reduce the window for slow loris attacks
• stdio mode is more secure than network modes (no network exposure)

Fields

port: u16

Port to listen on (for HTTP transport)

Default: 8080 Security: Use non-standard ports to reduce automated scanning. Consider using a reverse proxy for production deployments. Range: 1-65535 (ports < 1024 require root/admin privileges)

stdio: bool

Enable stdio transport (default for MCP)

Default: true (secure by default) Security: stdio is the most secure transport as it doesn’t expose a network interface. Recommended for local integrations. Trade-off: Limited to local process communication only

max_connections: usize

Maximum concurrent connections

Default: 100 Security: Prevents resource exhaustion attacks. Lower values are more secure but may impact legitimate high-traffic scenarios. Range: 1-10000 (recommend 10-500 for most deployments) Warning: Values > 1000 may cause memory issues under attack

request_timeout_secs: u64

Request timeout in seconds

Default: 30 seconds Security: Shorter timeouts prevent slow loris and resource holding attacks. Longer timeouts may be needed for complex operations. Range: 1-300 (recommend 10-60 for most use cases) Trade-off: Too short may interrupt legitimate long operations
