+# Grounding Lite
+
+Google Maps Grounding Lite provides AI-grounded location data via MCP. Use `mcporter` to call tools directly.
+
+**Status**: Experimental (pre-GA), free during preview.
+
+**Rate limits**: search_places (100 QPM, 1K QPD), lookup_weather (300 QPM), compute_routes (300 QPM).
+
+## Setup
+
+1. Install mcporter: `npm install -g mcporter`
+2. Set `GOOGLE_MAPS_API_KEY` environment variable
+3. Configure the MCP server (one-time):
+
+```bash
+mcporter config add grounding-lite \
+  --url https://mapstools.googleapis.com/mcp \
+  --header "X-Goog-Api-Key: $GOOGLE_MAPS_API_KEY"
+```
+
+### API Key Security
+
+1. **Restrict your API key** in Google Cloud Console:
+   - API restrictions: Allow only `mapstools.googleapis.com`
+   - Application restrictions: Use IP restriction if on a fixed server
+
+2. **Never hardcode keys** - use environment variables
+
+3. **For production**: Consider OAuth 2.0 (better audit trails)
+
+See: https://developers.google.com/maps/api-security-best-practices
+
+## Search Places
+
+Find places by text query with AI summaries:
+
+```bash
+mcporter call grounding-lite.search_places text_query="coffee shops near Central Park"
+```
+
+With location bias:
+
+```bash
+mcporter call grounding-lite.search_places \
+  text_query="pizza" \
+  location_bias='{"center":{"latitude":40.7829,"longitude":-73.9654},"radius":2000}'
+```
+
+JSON output:
+
+```bash
+mcporter call grounding-lite.search_places text_query="sushi in Tokyo" --output json
+```
+
+Response includes: place IDs, names, addresses, coordinates, Google Maps links, and AI summary.
+
+## Lookup Weather
+
+Get current weather:
+
+```bash
+mcporter call grounding-lite.lookup_weather location='{"address":"Tokyo, Japan"}' units_system=METRIC
+```
+
+By coordinates:
+
+```bash
+mcporter call grounding-lite.lookup_weather \
+  location='{"lat_lng":{"latitude":35.6762,"longitude":139.6503}}'
+```
+
+By place ID:
+
+```bash
+mcporter call grounding-lite.lookup_weather location='{"place_id":"ChIJ..."}'
+```
+
+Forecast for a specific date/hour:
+
+```bash
+mcporter call grounding-lite.lookup_weather \
+  location='{"address":"Paris, France"}' \
+  date='{"year":2026,"month":1,"day":28}' \
+  hour=14
+```
+
+Units: `METRIC` (Celsius, km/h) or `IMPERIAL` (Fahrenheit, mph).
+
+## Compute Routes
+
+Calculate distance and duration:
+
+```bash
+mcporter call grounding-lite.compute_routes \
+  origin='{"address":"San Francisco, CA"}' \
+  destination='{"address":"Los Angeles, CA"}' \
+  travel_mode=DRIVE
+```
+
+Walking route:
+
+```bash
+mcporter call grounding-lite.compute_routes \
+  origin='{"address":"Times Square, NYC"}' \
+  destination='{"address":"Central Park, NYC"}' \
+  travel_mode=WALK
+```
+
+Travel modes: `DRIVE` (default) or `WALK`.
+
+Note: Returns distance/duration only. No step-by-step directions or real-time traffic.
+
+## Ad-hoc Usage (without config)
+
+Call directly without configuring first:
+
+```bash
+mcporter call "https://mapstools.googleapis.com/mcp.search_places" \
+  --header "X-Goog-Api-Key: $GOOGLE_MAPS_API_KEY" \
+  text_query="restaurants near me"
+```
+
+## List Available Tools
+
+```bash
+mcporter list grounding-lite --schema
+```
+
+## vs goplaces / local-places
+
+| Feature | Grounding Lite | goplaces | local-places |
