## Description
7Timer! MCP.

## Tools
Capabilities this server exposes over MCP:

- **stargazing_forecast** — Astronomy observing forecast from 7Timer! ASTRO — the metrics stargazers and astrophotographers use to decide if tonight is good for observing: cloud cover, atmospheric seeing (steadiness), and sky transparency, at 3-hour resolution out to 72 hours. Each point gets a human-readable label and an obs…
- **weather_forecast** — General weather forecast from 7Timer! CIVIL — temperature, humidity, a weather condition code (e.g. clearday, pcloudynight, lightrainday, tsday), cloud cover, wind, and precipitation type, at 3-hour resolution out to 72 hours. Keyless.

## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `npx` (confidence: high):

```json

  "7timer": {
    "command": "npx",
    "args": ["-y","@pipeworx/mcp-7timer"]
  }
}
```

## Documentation

## What the 7timer MCP server does

The 7timer MCP server connects agents to forecast data from 7Timer!, exposing separate tools for everyday weather and astronomy observing. Both tools are keyless and return forecast information at three-hour intervals across a 72-hour period.

`weather_forecast` uses 7Timer! CIVIL data. Its results include temperature, humidity, a condition code such as `clearday`, `pcloudynight`, `lightrainday`, or `tsday`, cloud cover, wind, and precipitation type.

`stargazing_forecast` uses 7Timer! ASTRO data for observing decisions. It reports cloud cover, atmospheric seeing, and sky transparency. Each forecast point includes a readable description and an `observing_quality` verdict, while a `best_window` summary identifies the clearest and steadiest hours.

## How it works

The package supports two connection modes. A remote MCP client can connect to the Pipeworx endpoint at `https://gateway.pipeworx.io/7timer/mcp`. That endpoint exposes the two 7Timer tools alongside shared Pipeworx meta-tools, including routing and discovery functions. The gateway also provides access to the broader Pipeworx catalog through those shared tools.

For a focused local connection, run the package with `npx -y @pipeworx/mcp-7timer`. The local process communicates over standard input and output and exposes only the pack's own tools. It does not add the gateway's shared meta-tools or require a Pipeworx account.

The tools can also be called over HTTP without an MCP client. For example, the gateway provides `/v1/tools/stargazing_forecast` for direct POST requests with JSON input. Tool details can be inspected through the gateway's tool inspection endpoint.

## Setup and configuration

For a remote setup, add the gateway URL as an MCP server in a compatible client. For local stdio operation, configure the client to launch `npx` with `-y @pipeworx/mcp-7timer` as its argument.

No API key or environment variable is documented for either forecast tool. The gateway README states that no account is needed for the first calls, while the local package runs without a Pipeworx account.

## Tools and capabilities

- `weather_forecast`: Retrieves 7Timer! CIVIL weather data for a location.
- `stargazing_forecast`: Retrieves 7Timer! ASTRO observing conditions for a location.
- Three-hour forecast resolution out to 72 hours.
- Astronomy-specific measures for cloud cover, seeing, and transparency.
- Direct MCP, local stdio, and gateway HTTP access paths.

## Limitations and notes

Forecast results come from 7Timer! and are limited to the fields and time range supplied by its CIVIL and ASTRO services.

A gateway connection lists more tools than the two forecast tools because shared Pipeworx meta-tools are included. The local 7timer MCP server exposes only the pack-specific tools. Use the local mode when a narrow tool surface and no gateway round trip are preferred; use the gateway when Pipeworx routing or access to other catalog sources is needed.
