### Description (declared)

# CheerLights MCP server

An MCP server that lets Claude and other AI assistants read the live CheerLights color, its history, and statistics.

[CheerLights](https://cheerlights.com) is a global network of lights that all show the same color, set by anyone on the [CheerLights Discord](https://cheerlights.com/discord).
This server reads the public CheerLights feed (ThingSpeak channel 1417) and gives an assistant five read-only tools: the current color, recent history, statistics, search, and HEX and RGB values.
It is built on the MCP Python SDK 2.x and needs no API key.

## Quick start

You need [uv](https://docs.astral.sh/uv/), which installs Python 3.10 or later for you.
`uvx` runs the server straight from [PyPI](https://pypi.org/project/cheerlights-mcp/), with nothing else to install.

Add the server to Claude Code:

```bash
claude mcp add cheerlights -- uvx cheerlights-mcp
```

Or add it to Claude Desktop's `claude_desktop_config.json` and restart the app:

```json
{
  "mcpServers": {
    "cheerlights": {
      "command": "uvx",
      "args": ["cheerlights-mcp"]
    }
  }
}
```

Then ask: "What's the current CheerLights color?"
The assistant calls `get_current_cheerlights_color` and answers with the live color.

## Example

These results come from a live run of version 3.0.0 over stdio on 2026-10-28 (`examples/client_example.py`).

`get_current_cheerlights_color` returns the color, its HEX value, and when it was set:

```json
{
  "color": "purple",
  "hex": "#800…
