MCP with Playwright — Israeli Weather Forecast

An MCP server that gives an LLM the ability to control a real browser (via Playwright) and fetch weather forecasts for Israeli cities from weather2day.co.il, instead of calling a conventional weather API.

This project is the Israeli counterpart to the bundled weather_USA.py demo (which calls the US National Weather Service API). Here, the "API" is a human user's browsing flow, automated end-to-end.

How it works

1. open_weather_forecast_israel — opens a headless Chromium browser and navigates to https://www.weather2day.co.il/forecast.
2. enter_weather_forecast_city_israel — types the requested city name into the site's search box, triggering its autocomplete dropdown.
3. select_weather_forecast_city_israel — clicks the first suggestion in the dropdown, which navigates to that city's forecast page.
4. get_weather_forecast_content_israel — extracts the visible text of the resulting page, cleans it up, and hands it back to the LLM as context (RAG), so the LLM can answer the user's question directly in the chat instead of just leaving the browser open on the page.

The LLM (via host.py) decides on its own, based on the user's question, which of these 4 tools to call and in what order.

Setup

1. Install dependencies:

   uv sync
   

2. Install the Chromium browser for Playwright:

   uv run playwright install chromium
   

3. Copy .env.example to .env and fill in your GOOGLE_API_KEY.
4. Run the chat host:

   uv run host.py
   

⚠️ If a tool call fails / selectors need tuning

weather2day.co.il's exact HTML (class names, ids) can change, and the autocomplete widget is rendered dynamically by JavaScript. The 3 CSS selectors used in weather_Israel.py (search input, dropdown item, forecast content container) are defined as constants at the top of the file:

SEARCH_INPUT_SELECTOR = "..."
DROPDOWN_ITEM_SELECTOR = "..."
FORECAST_CONTENT_SELECTOR = "..."

If a tool call times out, the fastest fix is to record the real selectors yourself:

uv run playwright codegen https://www.weather2day.co.il/forecast

This opens a browser + Inspector panel. Click into the city search field and select a city manually — Playwright will show you the exact selector/action it recorded in the Inspector. Copy the corrected selector into the matching constant in weather_Israel.py.

Example questions to ask the Agent

• "מה התחזית להיום בתל אביב?"
• "האם צפוי גשם בחיפה השבוע?"
• "מה הטמפרטורה הצפויה בירושלים מחר?"
• "יש התראות מזג אוויר בבאר שבע?"
• (English also works) "What's the weather like in Eilat right now?"

The agent will pick the weather-Israel MCP server for Israeli cities and the weather-USA MCP server for US states/coordinates.

Notes

• The browser runs headless by default (no visible window). To watch it work while debugging, change headless=True to headless=False in open_weather_forecast_israel.
• Each call to open_weather_forecast_israel closes any previously-open browser session first, so re-asking a new question starts clean.
