[![PyPI - Version](https://img.shields.io/pypi/v/modbus-mcp.svg)](https://pypi.org/p/modbus-mcp)

A lightweight [Model Context Protocol (MCP)](https://modelcontextprotocol.io) server that connects LLM agents to [Modbus](https://en.wikipedia.org/wiki/Modbus) devices in a secure, standardized way, enabling seamless integration of AI-driven workflows with Building Automation (BAS) and Industrial Control (ICS) systems, allowing agents to monitor real-time sensor data, actuate devices, and orchestrate complex automation tasks.

## Getting Started

Use [uv](https://github.com/astral-sh/uv) to add and manage the Modbus MCP server as a dependency in your project, or install it directly via `uv pip install` or `pip install`. See the [Installation](https://github.com/ezhuk/modbus-mcp/blob/main/docs/modbus-mcp/installation.mdx) section of the documentation for full installation instructions and more details.

```bash
uv add modbus-mcp
```

The server can be embedded in and run directly from your application. By default, it exposes a `Streamable HTTP` endpoint at `http://127.0.0.1:8000/mcp/`.

```python
# app.py
from modbus_mcp import ModbusMCP

mcp = ModbusMCP()

if __name__ == "__main__":
    mcp.run(transport="http")
```

It can also be launched from the command line using the provided `CLI` without modifying the source code.

```bash
modbus-mcp
```

Or in an ephemeral, isolated environment using `uvx`. Check out the [Using tools](https://docs.astral.sh/uv/guides/tools/) guide for more details.

```bash
uvx modbus-mcp
```

### Configuration

For the use cases where most operations target a specific device, such as a Programmable Logic Controller (PLC) or Modbus gateway, its c…
