Trae CN Integration

This document describes how to integrate Foggy MCP service with ByteDance's Trae IDE.

About Trae

Trae is an AI-native IDE from ByteDance, with built-in models like Deepseek and Doubao. MCP protocol support was added in v1.3.0.

Prerequisites

• Trae CN v1.3.0 or higher
• Foggy MCP service running (see Quick Start)

Configuration Methods

Method 1: JSON Configuration (Recommended)

1. Open Trae IDE
2. Click Settings icon (top right) → MCP
3. Click Raw Configuration (JSON) button
4. Add the following to mcp.json:

{
  "mcpServers": {
    "foggy-dataset": {
      "url": "http://localhost:7108/mcp/analyst/rpc"
    }
  }
}

Method 2: MCP Market

If Foggy MCP is published to Trae MCP Market:

1. Click Settings → MCP → Add
2. Search for "foggy" or "dataset" in the market
3. Click add and configure

Endpoint Selection

Endpoint	Use Case	Description
/mcp/analyst/rpc	Data Analysis	Structured queries, recommended
/mcp/admin/rpc	Full Access	All tool permissions
/mcp/business/rpc	Simple Queries	Natural language only

Verify Configuration

After configuration, MCP service status shows in the MCP list:

• Green: Connection successful
• Red: Connection failed, click to view error

For issues, check logs:

• Windows: C:\Users\<username>\AppData\Roaming\Trae CN\logs
• macOS: ~/Library/Application Support/Trae CN/logs

Using with Agents

Trae's Builder with MCP is a built-in agent that automatically includes configured MCP services.

Usage Steps

1. Open AI Chat panel
2. Select Builder with MCP agent
3. Enter natural language query:

Query sales data for the last week, grouped by product category

Add to Custom Agent

You can add MCP service to custom agents:

1. Go to Agent Settings
2. Add foggy-dataset in Tools section
3. Agent will automatically call MCP tools

Usage Examples

Data Query

Query order statistics for the last 7 days

Data Analysis

Analyze sales data, find top 10 categories by revenue

Report Generation

Generate monthly sales comparison report by store

Code Generation

Query user table structure, generate TypeScript interface

Configuration with Authentication

If MCP service requires authentication:

{
  "mcpServers": {
    "foggy-dataset": {
      "url": "http://localhost:7108/mcp/analyst/rpc",
      "headers": {
        "Authorization": "Bearer your-token"
      }
    }
  }
}

Multi-Project Configuration

Configure multiple MCP services:

{
  "mcpServers": {
    "sales-data": {
      "url": "http://sales-server:7108/mcp/analyst/rpc"
    },
    "inventory-data": {
      "url": "http://inventory-server:7108/mcp/analyst/rpc"
    }
  }
}

Troubleshooting

MCP Service Shows Red

1. Check if MCP service is running:

   curl http://localhost:7108/actuator/health

2. Verify endpoint path is correct (use /rpc)

3. Check Trae logs for detailed error

Configuration Not Working

1. Ensure JSON format is correct
2. Restart Trae IDE
3. Verify URL is accessible

Tool Call Failed

1. Check MCP service logs
2. Verify datasource connection
3. Try simpler query for testing
