Struct McpClientConfig 

pub struct McpClientConfig {
    pub url: String,
    pub headers: HashMap<String, String>,
    pub connect_timeout: Option<Duration>,
    pub read_timeout: Option<Duration>,
}

Configuration for MCP client connections

This struct provides a protocol-agnostic way to configure connections to MCP servers. It can be used with both SSE and Streamable HTTP transports.

Example

use mcp_common::McpClientConfig;
use std::time::Duration;

let config = McpClientConfig::new("http://localhost:8080/mcp")
    .with_header("Authorization", "Bearer token123")
    .with_connect_timeout(Duration::from_secs(30));

Fields

url: String

Target URL for the MCP server

headers: HashMap<String, String>

HTTP headers to include in requests

connect_timeout: Option<Duration>

Connection timeout duration

read_timeout: Option<Duration>

Read timeout duration

Implementations

impl McpClientConfig

pub fn new(url: impl Into<String>) -> Self
