Remote-MCP Server: Enhanced Remote Model Context Protocol Communication

Overview: What is Remote-MCP Server?

Remote-MCP Server is a type-safe, bidirectional, and simple solution for remote communication and centralized management of model contexts in AI applications. It bridges the gap between local MCP servers and their remote counterparts, allowing developers to connect and manage model contexts from anywhere without waiting for future official implementations.

🔧 Core Features & MCP Capabilities

Remote-MCP Server introduces a type-safe client-server architecture that supports basic MCP command support, tool support, and prompt support. The server is designed to be crash-safe and includes an event subscription system for real-time notifications about resource changes, tool/prompt list updates, HTTP header support with custom headers and authentication middleware, and enhanced error handling.

⚙️ MCP Architecture & Protocol Implementation

Remote-MCP Server leverages a modern architecture that decouples the client from local servers. The proposed architecture below shows how remote clients connect to a centralized server hosted on a remote network, making it easier to manage model contexts across multiple locations or users.

🚀 Getting Started with Installation

Getting started with Remote-MCP Server involves both the client and server components. Here are steps to integrate it into your projects.

Install the Client Package

Install the necessary packages by running:

$ npm install @remote-mcp/client @trpc/client@next zod

Then, configure your MCP client settings as follows:

{
  "mcpServers": {
    "remote-mcp": {
      "command": "npx",
      "args": ["-y", "@remote-mcp/client"],
      "env": {
        "REMOTE_MCP_URL": "http://localhost:9512",
        "HTTP_HEADER_Authorization": "Bearer <token>"
      }
    }
  }
}

Code Your Own Remote MCP Server

After installing @remote-mcp/server, create a remote MCP server by following the example code:

import { MCPRouter, LogLevel } from "@remote-mcp/server";
import { createHTTPServer } from '@trpc/server/adapters/standalone';

import { z } from "zod";

// Create router instance
const mcpRouter = new MCPRouter({
  logLevel: LogLevel.DEBUG,
  name: "example-server",
  version: "1.0.0",
  capabilities: {
    logging: {},
  },
});

// Add example tool
mcpRouter.addTool(
  "calculator",
  {
    description:
      "Perform basic calculations. Add, subtract, multiply, divide. Invoke this every time you need to perform a calculation.",
    schema: z.object({
      operation: z.enum(["add", "subtract", "multiply", "divide"]),
      a: z.string(),
      b: z.string(),
    }),
  },
  async (args) => {
    const a = Number(args.a);
    const b = Number(args.b);

    let result: number;
    switch (args.operation) {
      case "add":
        result = Number(a) + b;
        break;
      case "subtract":
        result = a - b;
        break;
      case "multiply":
        result = a * b;
        break;
      case "divide":
        if (b === 0) throw new Error("Division by zero");
        result = a / b;
        break;
    }

    return {
      content: [{ type: "text", text: `${result}` }],
    };
  },
);

const appRouter = mcpRouter.createTRPCRouter();

void createHTTPServer({
  router: appRouter,
  createContext: () => ({}),
}).listen(Number(process.env.PORT || 9512));
