How do I use Uno MCP Stdio?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Uno MCP Stdio start the proxy" That's it!

Uno MCP Stdio

PyPI version Python 3.11+ License: MIT

Local stdio proxy for Uno MCP Gateway - Provides local proxy for MCP clients that don't support OAuth authentication.

🎯 Problem Solved

Many MCP clients (such as Manus, Cherry Studio) don't support OAuth 2.0 authentication and cannot directly connect to MCP servers that require authentication.

uno-mcp-stdio acts as a local proxy:

Communicates with MCP clients using stdio mode (supported by all clients)
Securely stores OAuth tokens locally
Proxies requests to remote Uno Gateway, automatically attaching authentication information

🚀 Quick Start

Installation

# Run directly with uvx (recommended)
uvx uno-mcp-stdio

# Or install with pip
pip install uno-mcp-stdio
uno-mcp-stdio

First Run

OAuth authentication is required on first run:

$ uvx uno-mcp-stdio
🔐 Authentication required
📋 Please open the following link in your browser to complete authentication:
   https://mcpmarket.cn/oauth/authorize?...

⏳ Waiting for authentication...
✅ Authentication successful! Token saved
🚀 Uno MCP Stdio is ready

Configure MCP Client

Configure stdio server in your MCP client:

Manus / Cherry Studio Configuration Example:

{
  "mcpServers": {
    "uno": {
      "command": "uvx",
      "args": ["uno-mcp-stdio"]
    }
  }
}

If installed with pip:

{
  "mcpServers": {
    "uno": {
      "command": "uno-mcp-stdio"
    }
  }
}

⚙️ Configuration

Environment Variables

Variable	Description	Default
`UNO_GATEWAY_URL`	Uno Gateway URL	`https://uno.mcpmarket.cn/mcp`
`UNO_CREDENTIALS_PATH`	Token storage path	`~/.uno-mcp/credentials.json`
`UNO_DEBUG`	Debug mode	`false`

Token Storage

Authenticated tokens are stored in ~/.uno-mcp/credentials.json:

{
  "access_token": "xxx",
  "refresh_token": "xxx",
  "expires_at": 1736345678,
  "token_type": "Bearer"
}

Clear Authentication

# Delete token file to re-authenticate
rm ~/.uno-mcp/credentials.json

🔐 Authentication Flow

1. Start uno-mcp-stdio
   │
   ▼
2. Check ~/.uno-mcp/credentials.json
   │
   ├─ Valid token → Proxy requests directly
   │
   └─ No/expired token → Start authentication flow
      │
      ▼
3. Start temporary HTTP server (localhost:random port)
   │
   ▼
4. Generate OAuth URL, display to user
   │
   ▼
5. User completes authorization in browser
   │
   ▼
6. MCPMarket callback to local server
   │
   ▼
7. Exchange token, save to file
   │
   ▼
8. Close temporary server, start proxying
