MCP Client

mcp-client is a client for calling MCP-compatible gateway endpoints.

It provides a small API for listing and invoking tools through a configured MCP gateway path. It is intentionally focused on the client side; MCP server implementations live in applications or framework layers.

Main Types

• McpGatewayClient: gateway client used by applications.
• McpTool: tool metadata returned by the gateway.
• McpContent: content item returned by MCP tool calls.
• McpToolCallResult: structured result for a tool invocation.

Usage

#![allow(unused)]
fn main() {
use mcp_client::McpGatewayClient;

let client = McpGatewayClient::new(gateway_url, path, timeout_ms);
let result = client.call_tool("tool.name", arguments).await?;
}

Consumers

light-agent uses this crate when an agent session needs to discover or invoke tools exposed through an MCP gateway.
