The simplest setup. Add to your MCP config:

{
  "mcpServers": {
    "burp": {
      "type": "sse",
      "url": "http://127.0.0.1:9876/sse"
    }
  }
}

Config file locations:

• Global: ~/.claude.json
• Per-project: .mcp.json in project root

Caddy prevents SSE timeout disconnections and provides reliable buffering.

Install Caddy:

sudo apt install caddy

Create /etc/caddy/Caddyfile:

:9900 {
    reverse_proxy 127.0.0.1:9876 {
        transport http {
            read_timeout 0
            write_timeout 0
            response_header_timeout 0
        }
        flush_interval -1
        header_up Connection {>Connection}
        header_up Upgrade {>Upgrade}
    }
}

sudo systemctl restart caddy

Then use port 9900 in your MCP config:

{
  "mcpServers": {
    "burp": {
      "type": "sse",
      "url": "http://127.0.0.1:9900/sse"
    }
  }
}

Claude Desktop only supports stdio transport. Use supergateway as a bridge:

{
  "mcpServers": {
    "burp": {
      "command": "npx",
      "args": ["-y", "supergateway", "--sse", "http://127.0.0.1:9876/sse"]
    }
  }
}

chmod +x configs/setup.sh
./configs/setup.sh
