The 2026 shift:<\/strong> MCP started as local-only (stdio). Now remote servers over HTTP are the default for production. GitHub, Stripe, Linear, Notion, and Cloudflare all publish hosted MCP endpoints. Here’s how to build and deploy your own.<\/p>\n

Building a Remote MCP Server<\/h2>\n

TypeScript with Express<\/h3>\n
import { McpServer } from \"@modelcontextprotocol\/sdk\/server\/mcp.js\";\nimport { StreamableHTTPServerTransport } from \"@modelcontextprotocol\/sdk\/server\/streamableHttp.js\";\nimport express from \"express\";\n\nconst app = express();\nconst server = new McpServer({ name: \"my-remote-server\" });\n\n\/\/ Define your tools\nserver.tool(\"hello\", { name: z.string() }, async ({ name }) => {\n  return { content: [{ type: \"text\", text: `Hello, ${name}!` }] };\n});\n\n\/\/ Mount MCP endpoint\napp.post(\"\/mcp\", async (req, res) => {\n  const transport = new StreamableHTTPServerTransport(\"\/mcp\");\n  await server.connect(transport);\n  await transport.handleRequest(req, res);\n});\n\napp.listen(3000);<\/code><\/pre>\n
Deploying<\/h2>\n
Option 1: Cloudflare Workers<\/h3>\n
Serverless, global, free tier. Cloudflare has first-class MCP support with their Workers platform. Deploy and get a URL instantly.<\/p>\n
Option 2: Vercel \/ Railway<\/h3>\n
Deploy as a standard Node.js app. Get a HTTPS URL. Add to any AI client.<\/p>\n
Option 3: Your own EC2\/VPS<\/h3>\n
Full control. Run behind nginx with SSL. Good for internal tools that shouldn’t be public.<\/p>\n
Authentication for Remote Servers<\/h2>\n
Remote MCP servers MUST have auth. Two patterns:<\/p>\n
API Key (Simple)<\/h3>\n
app.post(\"\/mcp\", (req, res, next) => {\n  const key = req.headers[\"authorization\"]?.replace(\"Bearer \", \"\");\n  if (key !== process.env.MCP_API_KEY) return res.status(401).json({ error: \"Unauthorized\" });\n  next();\n}, mcpHandler);<\/code><\/pre>\n
OAuth (Enterprise)<\/h3>\n
Redirect users to your OAuth flow, issue tokens, validate on each request. Required for multi-tenant deployments.<\/p>\n
Connecting Clients to Remote Servers<\/h2>\n
\/\/ Claude Desktop config\n{\n  \"mcpServers\": {\n    \"my-remote-tool\": {\n      \"url\": \"https:\/\/my-mcp-server.railway.app\/mcp\",\n      \"headers\": { \"Authorization\": \"Bearer sk_xxx\" }\n    }\n  }\n}<\/code><\/pre>\n
No command<\/code> needed for remote servers – just the URL and auth headers.<\/p>\n
