## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## FMI Weather + Fingrid Wind/Solar Nowcast Feed (`itulo/fmi-fingrid-nowcast`)

Hourly joined feature feed combining **Finnish Meteorological Institute (FMI)** WFS point weather forecasts across Finland's primary wind, solar, and demand hubs (`Oulu`, `Vaasa`, `Pori`, `Helsinki`, `Lappeenranta`) with **Fingrid Open Data** wind generation forecast (`245`), solar generation forecast (`248`), electricity consumption forecast (`166`), and actual wind generation (`75`).

Ships as both a **Pay-Per-Event Apify Actor** (`itulo/fmi-fingrid-nowcast`) and an open-source **stdio MCP Server** (`src/mcp-server.js`).

> **Independent Tool Notice:** Not affiliated with or endorsed by Fingrid Oyj or Ilmatieteen laitos (FMI). Uses zero Nord Pool or ENTSO-E day-ahead electricity exchange price data.

***

### Built for EV Smart-Charging, Home Automation & Nordic Energy Analytics

- **EV Smart-Charging Windows (`isEvChargeRecommended`):** Ranks the next 36 hours by renewable share (`windSolarSharePct`) and low residual load (`residualLoadMW`) without relying on restricted power-exchange spot prices.
- **Wind Hub & Storm Cut-Out Risk (`fmiStormCutoutRisk`):** Weights Ostrobothnia & West Coast wind hubs (`Oulu`, `Vaasa`, `Pori`) and flags turbine storm cut-out risk when hub gusts approach 25 m/s.
- **Demand-Weighted Heating Degree Hours (`fmiHeatingDegreeHoursC`):** Computes hourly heating demand pressure across southern and northern population centers alongside 1-hour wind & residual load ramps (`windRamp1hMW`, `residualRamp1hMW`).

***

### Pay-Per-Event Pricing (`PAY_PER_EVENT`)

| Event Name | Price (USD) | Description |
|---|---|---|
| `actor-start` | **$0.01 / run** | Flat fee for starting an Actor run |
| `nowcast-hour` | **$0.001 / hour** ($1.00 / 1,000) | Each joined FMI weather + Fingrid wind/solar/consumption hourly record written to the dataset (primary event) |

### Connect to Claude Desktop, Cursor & MCP Clients (Model Context Protocol)

You can use **`itulo/fmi-fingrid-nowcast`** as a live tool inside **Claude Desktop**, **Cursor**, **Windsurf**, or any MCP-compatible AI agent in two ways:

#### Option A: Hosted Apify MCP Server (`@apify/actors-mcp-server`)

Zero local setup required. Add this to your `claude_desktop_config.json` (macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`, Windows: `%APPDATA%\Claude\claude_desktop_config.json`) or Cursor `.cursor/mcp.json`:

```json
{
  "mcpServers": {
    "fmi-fingrid-nowcast": {
      "command": "npx",
      "args": [
        "-y",
        "@apify/actors-mcp-server",
        "--actors",
        "itulo/fmi-fingrid-nowcast"
      ],
      "env": {
        "APIFY_TOKEN": "YOUR_APIFY_API_TOKEN"
      }
    }
  }
}
```

#### Option B: Local Stdio MCP Server (Open-Source CLI)

Run the bundled stdio MCP server (`src/mcp-server.js`) directly on your machine. Exposed MCP tools: `fmi_fingrid_nowcast`, `fmi_station_weather`, `fmi_fingrid_licence_info`.

```json
{
  "mcpServers": {
    "fmi-fingrid-nowcast-local": {
      "command": "node",
      "args": [
        "/absolute/path/to/tools/fmi-fingrid-nowcast/src/mcp-server.js"
      ],
      "env": {
        "FINGRID_API_KEY": "YOUR_FREE_FINGRID_API_KEY"
      }
    }
  }
}

### Frequently Asked Questions (FAQ)

#### How does this actor combine FMI meteorological forecasts with Fingrid grid forecasts?

It fetches hourly HARMONIE-MEPS surface weather point forecasts from the Finnish Meteorological Institute (FMI WFS 2.0) across Finland’s primary wind, solar, and demand hubs (`Oulu`, `Vaasa`, `Pori`, `Helsinki`, `Lappeenranta`) and joins them by UTC hour with Fingrid Open Data wind generation forecast (`245`), solar forecast (`248`), consumption forecast (`166`), and 15-min actual wind generation (`75`).

#### What derived energy & EV smart-charging signals are included?

Each hourly record includes capacity-weighted hub wind speed (`fmiWindSpeedWeightedMs`), max hub wind gusts & storm cut-out risk (`fmiStormCutoutRisk` at >=25 m/s), demand-weighted temperature & heating degree hours (`fmiHeatingDegreeHoursC`), 1-hour wind and residual load ramps (`windRamp1hMW`, `residualRamp1hMW`), and an EV smart-charging recommendation rank (`isEvChargeRecommended`, `nowcastScore`).

#### Does `weather_only` mode work without a Fingrid API key?

Yes! Set `mode: "weather_only"` (or call the `fmi_station_weather` MCP tool) to run 100% keyless using only FMI WFS open data. For `joined_nowcast` or `ev_charging_windows`, pass your free `fingridApiKey`.

## MCP server setup

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
