Struct HttpClientTransport

Source 
pub struct HttpClientTransport { /* private fields */ }
Expand description

HTTP transport for MCP clients

This transport communicates with an MCP server via HTTP requests and optionally uses Server-Sent Events for real-time notifications.

Implementations§

Source§

impl HttpClientTransport

Source

pub async fn new<S: AsRef<str>>( base_url: S, sse_url: Option<S>, ) -> McpResult<Self>

Create a new HTTP client transport

§Arguments
  • base_url - Base URL for the MCP server
  • sse_url - Optional URL for Server-Sent Events (for notifications)
§Returns

Result containing the transport or an error

Source

pub async fn with_config<S: AsRef<str>>( base_url: S, sse_url: Option<S>, config: TransportConfig, ) -> McpResult<Self>

Create a new HTTP client transport with custom configuration

§Arguments
  • base_url - Base URL for the MCP server
  • sse_url - Optional URL for Server-Sent Events
  • config - Transport configuration
§Returns

Result containing the transport or an error

Source

pub async fn active_request_count(&self) -> usize

Get count of active requests (for debugging/metrics)
