Verdicts

AccuWeather Core Weather API + MCP

Official hosted MCP server, 26 read-only tools, same key as the REST API. Terms forbid using the data to train, validate or otherwise inform any AI system.

Google Weather API (Maps Platform)

Covered by the Maps Platform SLA, 99.9 per cent with service credits. History is 24 hours only, and bulk data isn't available.

Before you call either

AccuWeather Core Weather API + MCP

  1. Cache location keys. They don't change, and the lookup is the call worth saving
  2. Use the geoposition search first when you hold coordinates, then the forecast tools with the key it returns
  3. Send the key as a Bearer header, not in the MCP URL, so it stays out of logs
  4. Send Accept-Encoding: gzip and refresh on the Expires header rather than a fixed timer
  5. Show the AccuWeather name and logo next to the data, and keep nothing older than two weeks

Google Weather API (Maps Platform)

  1. Ask for only the days or hours you need, one location a call. Every call is one billable event
  2. Page with pageSize and pageToken rather than asking for 240 hours at once
  3. Check the coverage page before promising alerts. Coverage is by country
  4. Refetch rather than cache. The Maps terms give no caching window for weather content
  5. Restrict the key to the Weather API and your server IPs in the Cloud console
