Description

Network Debugger
Professional network debugging tool for macOS

Network Debugger helps developers and testers quickly build TCP and UDP connections, send and inspect messages, and automate repetitive tasks. Focus on your protocol logic instead of wiring up temporary tools.

Key features

• TCP & UDP support (client & server)
• Multiple connections with clear status indicators
• Message templates for frequently used payloads
• One-click send and resend
• Automatic replies based on matching messages
• UTF-8 and other encodings
• Built-in MCP Server (HTTP/SSE) for external tool & agent integration
• Clean, modern interface with light & dark modes

MCP Server (HTTP/SSE)

Network Debugger includes a built-in MCP Server over HTTP/SSE, allowing external tools or agents to control your debugging sessions and build repeatable workflows.

With MCP, you can:

• List, create, open, close, and delete connections
• Send data through a connection
• Check connection status
• Fetch recent messages for inspection and automation

Use MCP to orchestrate test flows, drive message sends from scripts or agents, and integrate Network Debugger into your automation pipeline—while keeping everything running locally on your Mac.

UDP workflows

Use UDP when you need lightweight, connectionless messaging—ideal for device discovery, LAN broadcast/multicast, telemetry, and IoT protocols. Quickly bind to a local port, send datagrams to a target host/port, and inspect incoming packets in clear, timestamped logs.

Message templates

Save frequently used messages as templates and send them with a single click. Great for quickly simulating login, heartbeat, and business flows without retyping.

Automated test scenarios

Define auto-reply rules for specific messages to simulate real-world services. Easily build end-to-end test scenarios and long-running integrations without manual intervention. With MCP, you can also trigger sends and fetch messages programmatically for fully automated runs.

Designed for productivity

A focused, distraction-free UI, keyboard-friendly operations, and clear logs help you locate problems faster and keep your network debugging workflow smooth.

Privacy

All data is processed locally on your Mac. No messages are uploaded to any server.
