bannin 0.1.0

Universal monitoring platform — watch your machines, LLMs, notebooks, and coding tools from your phone.

Bannin

番人 (Japanese for "watchman") — a universal monitoring agent for your machine, your LLMs, and your cloud notebooks.

You hit run. You walk away. Then what?

---

What It Does

Bannin runs on your machine (or inside a cloud notebook) and monitors everything: CPU, RAM, GPU, disk, running processes, LLM conversation health, API usage, and cloud session health. It predicts out-of-memory crashes before they happen, scores your AI conversation quality, fires smart alerts, and gives you plain-English summaries of how your system is doing.

It also works as an MCP server — meaning AI coding tools (Claude Code, Cursor, Windsurf) can query your system health through natural conversation.

Install

pip install bannin

With GPU monitoring and MCP server support:

pip install "bannin[all]"

Quick Start

Start the agent:

bannin start

Open the dashboard:

Visit localhost:8420 in your browser.

Use with Claude Code (MCP):

Add to your .mcp.json:

{
  "mcpServers": {
    "bannin": {
      "command": "python",
      "args": ["-m", "bannin.mcp"]
    }
  }
}

Then ask Claude things like:

• "How's my system doing?"
• "What processes are using the most memory?"
• "Am I going to run out of RAM?"
• "How healthy is this conversation?"

Python API

import bannin

# Monitor system during a block of code
with bannin.watch():
    train_model()

# Wrap an LLM client to track tokens and cost
import openai
client = bannin.wrap(openai.OpenAI())

# Track a specific scope
with bannin.track("my-experiment"):
    response = client.chat.completions.create(...)

CLI

bannin start                    # Start the agent (dashboard at localhost:8420)
bannin start --port 9000        # Start on a custom port
bannin mcp                      # Start the MCP server (stdio transport)
bannin analytics                # Start the analytics dashboard (port 8421)
bannin history                  # Query stored event history
