1Panel + mcp-use: Complete MCP Integration

1Panel is a MCP server that MCP server implementation that provides 1Panel interaction.

When integrated with mcp-use, you can:

• Monitor system status and dashboard information
• Create and manage websites on 1Panel
• Handle SSL certificates and HTTPS configuration

This guide provides step-by-step instructions to set up 1Panel in mcp-use, including configuration, examples, and troubleshooting.

What You'll Achieve

After completing this setup:

• 1Panel will be fully integrated and operational
• You can use 1Panel tools directly in mcp-use
• All 1Panel capabilities will be available for your workflows
• Access to 5 different tools

Prerequisites

Before starting, ensure you have:

• 1Panel access token for authentication
• 1Panel server address
• mcp-use installed and configured
• Compatible operating system (Python 3.8+, Node.js 16+, pip Installation, npm/yarn Installation)

Installation

Step 1: Install 1Panel

Configuration

Step 2: Configure mcp-use

1. Open mcp-use settings
2. Navigate to MCP server configuration
3. Add 1Panel server with appropriate settings
4. Save and restart if needed

Examples

Once configured, you can use 1Panel in mcp-use:

Get System Overview

Check 1Panel server status and system information

Ask mcp-use: "Show me the dashboard information and system status"

Expected Result: Dashboard data including CPU, memory, disk usage, and running services

Create New Website

Set up a new website with domain configuration

Ask mcp-use: "Create a website for domain example.com with PHP support"

Expected Result: Website created with virtual host configuration and PHP environment

Install Database Server

Install and configure MySQL server

Ask mcp-use: "Install MySQL and create a database called myapp_db"

Expected Result: MySQL installed, database created, and connection details provided

SSL Certificate Setup

Generate and configure SSL certificate for website

Ask mcp-use: "Create an SSL certificate for my website example.com"

Expected Result: SSL certificate generated and configured for HTTPS access

Testing Your Setup

1. Launch mcp-use
2. Verify 1Panel is available in the tools list
3. Test basic 1Panel functionality

Troubleshooting

Common Issues

Authentication Failed

Symptoms: Access denied errors, Invalid token messages, Connection refused

Cause: Invalid or missing PANEL_ACCESS_TOKEN

Solution:

• Verify PANEL_ACCESS_TOKEN is set correctly
• Check token validity in 1Panel admin interface
• Ensure token has sufficient permissions

Connection to 1Panel Failed

Symptoms: Connection timeout, Server unreachable, Network errors

Cause: Invalid PANEL_HOST or 1Panel server not running

Solution:

• Verify PANEL_HOST URL is correct
• Check 1Panel server is running on specified port
• Test network connectivity to 1Panel server
• Ensure firewall allows connections

SSE Mode Not Working

Symptoms: SSE endpoint not responding, Transport errors

Cause: Incorrect SSE configuration or port conflicts

Solution:

• Verify -addr parameter is accessible
• Check port is not in use by another service
• Ensure SSE transport is specified correctly
• Test SSE endpoint with curl

Binary Not Found

Symptoms: Command not found, mcp-1panel: command not found

Cause: Binary not in PATH or not properly installed

Solution:

• Verify binary is in /usr/local/bin or system PATH
• Check file permissions (executable bit)
• Re-download and reinstall binary
• Use full path to binary if needed

Connection Refused or Server Unreachable

Symptoms: ECONNREFUSED error, Connection timeout, Cannot reach server

Cause: MCP server not running or incorrect URL

Solution:

• Verify MCP server is running and accessible
• Check server URL is correct (protocol, host, port, path)
• Test server URL in browser or with curl to confirm it responds
• Ensure firewall allows connections to server port
• Verify CORS settings if accessing from browser

Import Errors or Module Not Found

Symptoms: ModuleNotFoundError: mcp_use, Cannot find module "mcp-use"

Cause: Package not installed or wrong environment

Solution:

• Verify installation: pip show mcp-use (Python) or npm list mcp-use (JS)
• Ensure using correct Python virtual environment or Node.js project
• Reinstall package: pip install --upgrade mcp-use or npm install mcp-use
• Check package.json or requirements.txt includes mcp-use

Tool Discovery Returns Empty List

Symptoms: list_tools() returns [], No tools available, Tools not found

Cause: MCP server not properly configured or not exposing tools

Solution:

• Verify MCP server is properly initialized and configured
• Check server logs to confirm tools are registered
• Test server directly with MCP inspector or test client
• Ensure server implements MCP protocol correctly
• Verify transport type (HTTP/SSE) matches server configuration

Tool Execution Fails or Returns Errors

Symptoms: Tool call throws exception, Invalid arguments error, Execution timeout

Cause: Incorrect arguments or server-side execution failure

Solution:

• Verify tool arguments match schema definition from list_tools()
• Check required arguments are provided with correct types
• Review server logs for detailed error messages
• Test tool with minimal valid arguments first
• Increase timeout if tool requires longer execution time

LangChain.js Integration Not Working

Symptoms: getLangChainTools() fails, Tools not recognized by agent, Type errors

Cause: Version mismatch or incorrect integration setup

Solution:

• Ensure LangChain.js version is compatible with mcp-use
• Verify TypeScript version meets requirements
• Check tool schema conversion is working correctly
• Use latest versions of both mcp-use and LangChain.js
• Review LangChain.js documentation for agent setup

Transport Type Errors (HTTP vs SSE)

Symptoms: SSE connection fails, HTTP polling not working, Event stream errors

Cause: Mismatch between client transport and server capabilities

Solution:

• Verify server supports the transport type you are using
• Try alternative transport: switch between "http" and "sse"
• Check server documentation for supported transport types
• For SSE, ensure server sends proper Content-Type: text/event-stream
• For HTTP, verify server accepts POST requests with JSON payload

1Panel not appearing in mcp-use

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

• Verify configuration syntax
• Check 1Panel installation
• Restart mcp-use
• Check logs for error messages
