- Maintenance & community, Meteosource Weather MCP +70: Met Office Weather DataHub (Site Specific) 0 (No dated API change or release note found. The official utilities have no tag since public-2025.1.1 (18 June 2025). The site-specific script last changed in December 2023. The 11 February 2026 commit removed a beta label from two README files for the probabilistic forecast, and the 22 September commit fixed only the atmospheric download script, so none sets recency for this API (0). No dated API changes in the 90 days from 7 August (0). Support routes were read only on the struck hub, and no public changelog was found (0). No SDK or MCP server (0). The utilities repository has no CI (0). Total 0.); Meteosource Weather MCP 70 (Repository commit and tag v0.1.2 on 26 October 2026 (30). Three tags in 90 days (20). Repository issues not read (0).

- Schema & documentation, Meteosource Weather MCP +40: Met Office Weather DataHub (Site Specific) 32 (datahub.metoffice.gov.uk answered robots.txt on 5 November with a redirect to its sign-in page, so readings from that host (overview, pricing, FAQ, service status) are struck.

The official utilities' documentation, re-read on 5 November, says what the site-specific script retrieves and explains each parameter, with little on when to use which product (12 of 20, partial carried). `timesteps` takes hourly, three-hourly or daily, latitude must be between -90 and 90 and longitude between -180 and 180, and the key, latitude and longitude are required (10 of 15). Example commands and sample code, with no error responses documented on a readable page (7 of 15, partial carried). The path is /v0 and there's no changelog (3 of 15). Total 32.); Meteosource Weather MCP 72 (Seven tools read from tools/list with JSON Schema inputs (25). No llms.txt found; the README is Markdown on GitHub (5 of 10).
