# MCP Hub
[](https://www.npmjs.com/package/mcp-hub)
[](https://opensource.org/licenses/MIT)
[](./CONTRIBUTING.md)
MCP Hub acts as a central coordinator for MCP servers and clients, providing two key interfaces:
1. **Management Interface** (/api/*): Manage multiple MCP servers through a unified REST API and web UI
2. **MCP Server Interface** (/mcp): Connect ANY MCP client to access ALL server capabilities through a single endpoint
This dual-interface approach means you can manage servers through the Hub's UI while MCP clients (Claude Desktop, Cline, etc.) only need to connect to one endpoint (`localhost:37373/mcp`) to access all capabilities. Implements [MCP 2025-03-26](https://modelcontextprotocol.io/specification/2025-03-26) specification.

## Simplified Client Configuration
Configure all MCP clients with just one endpoint:
```json
{
"mcpServers" : {
"Hub": {
"url" : "http://localhost:37373/mcp"
}
}
}
```
The Hub automatically:
- Namespaces capabilities to prevent conflicts (e.g., `filesystem__search` vs `database__search`)
- Routes requests to the appropriate server
- Updates capabilities in real-time when servers are added/removed
- Handles authentication and connection management
## Key Features
- **Unified MCP Server Endpoint** (/mcp):
- Single endpoint for ALL MCP clients to connect to
- Access capabilities from all managed servers through one connection
- Automatic namespacing prevents conflicts between servers
- Real-time capability updates when servers change
- Simplified client configuration - just one endpoint instead of many
- **Dynamic Server Management**:
- Start, stop, enable/disable servers on demand
- Real-time configuration updates with automatic server reconnection
- Support for local (STDIO) and remote (streamable-http/SSE) MCP servers
- Health monitoring and automatic recovery
- OAuth authentication with PKCE flow
- Header-based token authentication
- **Unified REST API**:
- Execute tools from any connected server
- Access resources and resource templates
- Real-time status updates via Server-Sent Events (SSE)
- Full CRUD operations for server management
- **Real-time Events & Monitoring**:
- Live servExcerpt of 33,782 characters
