1Panel + LibreChat: Complete MCP Integration

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

When integrated with LibreChat, 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 LibreChat, 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 LibreChat
• 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
• LibreChat installed and configured
• Compatible operating system (Docker (Recommended), Kubernetes, Local Installation, Cloud Platforms)

Installation

Step 1: Install 1Panel

Configuration

Step 2: Configure LibreChat

1. Open LibreChat 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 LibreChat:

Get System Overview

Check 1Panel server status and system information

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

Expected Result: SSL certificate generated and configured for HTTPS access

Testing Your Setup

1. Launch LibreChat
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

MCP Server Not Connecting

Symptoms: Status shows "Disconnected" or "Error", Server not appearing in list, Connection timeout

Cause: Invalid configuration, missing dependencies, or server startup failure

Solution:

• Check librechat.yaml syntax is valid YAML
• Verify npx and Node.js are available (for stdio/command-based servers)
• Check server command and args are correct
• Review LibreChat logs for error messages: docker logs librechat
• Increase timeout value if server takes longer to initialize
• Ensure required ports are not blocked (for HTTP-based servers)

OAuth Authentication Failing

Symptoms: Status shows "OAuth Required", Redirect loop during auth, Token refresh errors

Cause: OAuth credentials not configured or redirect URLs incorrect

Solution:

• Verify OAuth clientId and clientSecret in librechat.yaml
• Check redirect URL is correctly set in OAuth provider settings
• Ensure authorizationUrl and tokenUrl are accessible
• Complete OAuth flow by clicking "Initialize" in MCP Settings panel
• Check browser console for OAuth-related errors

User Credentials Not Working

Symptoms: Prompts for credentials not appearing, Variables not substituted, Authentication errors

Cause: User credential variables incorrectly formatted or not entered

Solution:

• Use correct format: {{USER_VARIABLE_NAME}} in librechat.yaml
• Enter credentials through MCP Settings panel in UI
• Verify variable names match between config and UI
• Check credentials are saved per-user (not shared globally)

Tools Not Appearing in Chat

Symptoms: No tool dropdown available, MCP tools missing from interface, Server connected but tools unavailable

Cause: MCP server not properly integrated with chat endpoint or agent

Solution:

• Verify you are using an endpoint that supports MCP (not all models do)
• Check if Agent Builder is enabled and MCP tools are assigned to agent
• Restart chat session after adding new MCP servers
• Verify MCP server actually provides tools (some servers are resource-only)
• Check server logs to confirm tools are being discovered

Docker Deployment Problems

Symptoms: Container fails to start, Database connection errors, Port conflicts

Cause: Docker configuration issues or missing environment variables

Solution:

• Verify .env file is properly configured with all required variables
• Check MongoDB connection string is correct
• Ensure ports 3080 (frontend) and 3081 (backend) are available
• Run docker compose logs to view detailed error messages
• Verify Docker and Docker Compose versions meet minimum requirements

Performance Issues with MCP

Symptoms: Slow tool execution, Timeout errors, UI freezing during tool calls

Cause: Server timeout too short, inefficient MCP server, or network latency

Solution:

• Increase timeout values in librechat.yaml (both init and operation timeouts)
• Use HTTP transport instead of stdio for remote servers
• Monitor MCP server performance independently
• Consider caching for frequently accessed resources
• Use Streamable HTTP transport for production environments

1Panel not appearing in LibreChat

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

• Verify configuration syntax
• Check 1Panel installation
• Restart LibreChat
• Check logs for error messages
