1Panel + OpenCode: Complete MCP Integration

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

When integrated with OpenCode, 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 OpenCode, 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 OpenCode
• 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
• OpenCode installed and configured
• Compatible operating system (macOS, Linux, Windows)

Installation

Step 1: Install 1Panel

Configuration

Step 2: Configure OpenCode

1. Locate your configuration file:

2. Add server configuration:

Configure MCP servers in your `opencode.json` or `opencode.jsonc`:

```json
{
  "mcp": {
    "my-mcp": {
      "type": "local",
      "command": ["npx", "-y", "@modelcontextprotocol/server-everything"],
      "environment": {
        "API_KEY": "$API_KEY"
      },
      "timeout": 5000
    },
    "remote-server": {
      "type": "remote",
      "url": "https://mcp.example.com/sse",
      "headers": {
        "Authorization": "Bearer $API_TOKEN"
      }
    }
  }
}

Disable a server temporarily:

{
  "mcp": {
    "my-mcp": {
      "type": "local",
      "command": ["npx", "-y", "mcp-server"],
      "enabled": false
    }
  }
}

3. **Restart OpenCode**

Completely quit and restart OpenCode to load the new configuration.



## Examples

Once configured, you can use 1Panel in OpenCode:

### Get System Overview

Check 1Panel server status and system information

**Ask OpenCode:** "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 OpenCode:** "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 OpenCode:** "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 OpenCode:** "Create an SSL certificate for my website example.com"

**Expected Result:** SSL certificate generated and configured for HTTPS access



## Testing Your Setup

1. Run opencode in terminal
2. Add "use the mcp_name tool" to your prompts
3. Verify tool execution and response



## 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

#### MCP Server Not Loading

**Symptoms:** Server not appearing in tools, Timeout errors, Command not found

**Cause:** Invalid configuration, missing dependencies, or timeout too short

**Solution:**
- Verify command array is correct in opencode.json
- Check environment variables are set properly
- Increase timeout value if server takes longer to start
- Test MCP server command independently in terminal

#### Context Limit Exceeded

**Symptoms:** Context too large errors, Slow responses, Truncated output

**Cause:** Too many MCP servers adding to context

**Solution:**
- Disable unused MCP servers with enabled: false
- Use per-agent tool configuration to limit active MCPs
- Avoid MCP servers that add many tokens (e.g., GitHub MCP)

#### Remote Server Connection Failed

**Symptoms:** Cannot connect to remote MCP, Authentication errors

**Cause:** Invalid URL, missing headers, or network issues

**Solution:**
- Verify remote server URL is correct
- Check authorization headers are properly configured
- Ensure environment variables for tokens are set

#### 1Panel not appearing in OpenCode

**Symptoms:** Server not listed, Tools not available

**Cause:** Configuration or installation issue

**Solution:**
- Verify configuration syntax
- Check 1Panel installation
- Restart OpenCode
- Check logs for error messages
