MCP Setup

What is MCP?

Model Context Protocol is an open standard that enables AI assistants to interact with external systems through a unified interface. In DevBoxer, MCP servers provide DevBoxer with additional capabilities beyond code editing.

Configuring MCP Servers

Configuration Format

MCP configurations use JSON format with the following structure:

{
  "mcpServers": {
    "server-name": {
      // Server configuration
    }
  }
}

Server Types

DevBoxer supports three types of MCP servers:

1. Command-based Servers

Command-based servers run as local processes within your sandbox:

{
  "mcpServers": {
    "my-custom-server": {
      "command": "node",
      "args": ["/path/to/server.js"],
      "env": {
        "API_KEY": "your-api-key",
        "OTHER_CONFIG": "value"
      }
    }
  }
}

• command (required): The executable command to run
• args (optional): Array of command-line arguments
• env (optional): Environment variables to pass to the server

2. HTTP-based Servers

HTTP-based servers connect to remote MCP endpoints using standard HTTP requests:

{
  "mcpServers": {
    "context7": {
      "type": "http",
      "url": "https://mcp.context7.com/mcp",
      "headers": {
        "Authorization": "Bearer your-token"
      }
    }
  }
}

• type (required): Must be "http" for HTTP servers
• url (required): The full URL of the MCP endpoint
• headers (optional): HTTP headers to include with requests
• env (optional): Environment variables for the server

3. SSE-based Servers

SSE (Server-Sent Events) servers connect to MCP endpoints that use server-sent events for real-time communication:

{
  "mcpServers": {
    "sse-server": {
      "type": "sse",
      "url": "https://example.com/mcp-sse",
      "headers": {
        "Authorization": "Bearer your-token"
      }
    }
  }
}

• type (required): Must be "sse" for SSE servers
• url (required): The full URL of the SSE endpoint
• headers (optional): HTTP headers to include with the connection
• env (optional): Environment variables for the server

Multiple Servers

You can configure multiple MCP servers in a single configuration:

{
  "mcpServers": {
    "custom-tools": {
      "command": "python",
      "args": ["/home/user/mcp-server.py"]
    },
    "context7": {
      "type": "http",
      "url": "https://mcp.context7.com/mcp"
    },
    "sse-server": {
      "type": "sse",
      "url": "https://example.com/mcp-sse"
    },
    "another-server": {
      "command": "mcp-server",
      "env": {
        "CONFIG_PATH": "/etc/mcp/config.yaml"
      }
    }
  }
}
