What is MCP Hub?

MCP Hub is an intelligent central system that can connect multiple AI services (MCP servers) simultaneously. It allows you to use various AI functions provided by different servers through a simple interface, such as text generation and image processing.

How to use MCP Hub?

After installation, add the AI services you need through the configuration file, and then interact with these services through the REST API or the SSE real - time event system.

Use cases

Suitable for developers who need to use multiple AI services simultaneously or enterprise teams who want to manage AI tools uniformly.

Main features

Multi - server management

Connect multiple local and remote MCP servers simultaneously and manage their tools and resources uniformly.

Real - time monitoring

Get notifications such as server status changes and tool list updates in real - time through SSE.

Service marketplace

Built - in MCP server marketplace for easy discovery and installation of new services.

Automatic recovery

Automatically detect and recover disconnected server connections.

Advantages

Simplify the management complexity of multiple AI services

Provide a unified API interface

Real - time status monitoring and automatic recovery

Support multiple local and remote connection methods

Limitations

Currently does not support some advanced MCP functions such as Roots and Sampling

Requires basic technical knowledge for initial configuration

How to use

Installation

Install MCP Hub globally via npm

Configuration

Create a JSON configuration file to define the MCP servers to connect to

Startup

Run the MCP Hub service

Usage examples

Collaboration of multiple AI services

Use text generation and image processing services simultaneously to complete content creation

Real - time monitoring

Monitor the status and tool updates of all connected servers

🚀 MCP Center

The MCP Center is a central system designed to coordinate communication between clients and multiple MCP servers. It offers a unified interface to manage tools, resources, and prompt requests, while maintaining up - to - date capability information for each MCP server.

🚀 Quick Start

The MCP Center is a central system that coordinates communication between clients and multiple MCP servers. It manages tools, resources, and prompt requests through a unified interface and maintains the latest capability information for each MCP server.

✨ Features

Events

The following are the main events supported by the MCP Center:

hub.start: Indicates the startup of the MCP Center.
hub.stop: Indicates the shutdown of the MCP Center.
server.connected: Indicates that an MCP server has connected to the center.
server.disconnected: Indicates that an MCP server has disconnected from the center.
tool.request: Represents a client's request for tool execution.
resource.request: Represents a client's request for resource access.
prompt.request: Represents a client's request for prompt processing.
error.log: Records error events.

Architecture Overview

The architecture design of the MCP Center is as follows:

Startup and MCP Server Connection
- Start the MCP Center and initialize the configuration.
- Attempt to connect to all configured MCP servers.
SSE Client Connection Handling
- Handle Server - Sent Events connections from clients.
- Publish status updates of the MCP Center, such as startup and shutdown.
Tool and Resource Request Routing
- Validate the validity of client requests.
- Route requests to the appropriate MCP servers for processing.
- Handle responses or errors from MCP servers.
MCP Server Health Monitoring
- Regularly check the connection status and capability information of MCP servers.
- Attempt to reconnect when a fault is detected.
Graceful Startup and Shutdown Process
- Manage the startup and shutdown operations of the MCP Center.
- Notify all clients during the shutdown process.

Request Handling

The standard process for the MCP Center to handle tool, resource, and prompt requests is as follows:

Request Validation
- Validate the validity and integrity of client requests.
- Check if the target MCP server is in a normal connection state.
Route Requests to MCP Servers
- Select the appropriate MCP server for processing based on the request type.
- Send encrypted and signed requests to the target server.
Response Handling and Error Management
- Receive responses or error information from MCP servers.
- Return the results to the client and log errors when they occur.

📦 Installation

Dependencies

Node.js version requirement: 18.0.0 or higher
mcp - marketplace library: Used to provide the functionality of the MCP server marketplace

Marketplace Integration

The MCP Center currently relies on the mcp - marketplace library to implement marketplace functionality. This library provides the following main features:

Server Registration
- Allows MCP servers to register with the center.
- Provides API interfaces to manage the server list.
Capability Verification
- Verifies whether the capabilities of MCP servers meet the requirements.
- Maintains the latest server capability information.
Request Routing
- Matches the most suitable MCP server based on client requests.
- Manages request distribution and response collection.
Monitoring and Alerts
- Implements real - time monitoring of the health status of MCP servers.
- Triggers an alert mechanism when a fault is detected.
