Python SDK

from mcp.client.streamable_http import streamablehttp_client
from mcp import ClientSession

async with streamablehttp_client(
    "https://mcp-server-production-c654.up.railway.app/mcp",
    headers={"Authorization": "Bearer kstk_YOUR_KEY"}
) as (read, write, _):
    async with ClientSession(read, write) as session:
        await session.initialize()

        # List available tools
        tools = await session.list_tools()

        # Call a tool
        result = await session.call_tool(
            "search_ab_tests",
            {"query": "hero headline", "max_results": 5}
        )

TypeScript SDK

import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp.js";

const transport = new StreamableHTTPClientTransport(
  new URL("https://mcp-server-production-c654.up.railway.app/mcp"),
  { requestInit: { headers: { Authorization: "Bearer kstk_YOUR_KEY" } } }
);

const client = new Client({ name: "my-app", version: "1.0.0" });
await client.connect(transport);

const result = await client.callTool({
  name: "search_ab_tests",
  arguments: { query: "CTA button color", max_results: 10 }
