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).

The DataHub's docs, pricing and terms sit on a host that redirects robots.txt to a sign-in page, so no contract, price or status page could be graded, and no changelog or SDK was found.\n\n**Meteosource Weather MCP.** Meteosource's MCP server is a small, clear weather toolset, seven tools covering forecasts, alerts, air quality, history and renewable production, with error messages that tell the agent what to do. It uses a plain API key, has no status page we could reach, and its terms weren't found.\n\n## Before you call either\n\n### Met Office Weather DataHub (Site Specific)\n\n1. Send the key in the `apikey` header to https://data.hub.api.metoffice.gov.uk/sitespecific/v0/point/{timesteps} with latitude and longitude as query parameters\n2. Use hourly, three-hourly or daily as the timestep. The official script accepts no other value\n3. Add excludeParameterMetadata=true to drop the parameter descriptions from every response\n4. Read the plan's daily limit and licence terms when ordering on the DataHub, since they sit behind its sign-in\n\n### Meteosource Weather MCP\n\n1. Call search_places first to resolve a location\n2. Split history requests over 400 location-days into shorter ranges\n3. Production tools need the Renewables plan; check which tools the key exposes\n4. Send the key in a header, never in a URL\n\n## Questions\n\n### Which is better for AI agents, Met Office Weather DataHub (Site Specific) or Meteosource Weather MCP?\n\nMeteosource Weather MCP scores 50.9 (D) on agent readiness against Met Office Weather DataHub (Site Specific)'s 30 (F), and leads in 5 of 7 scored categories. Met Office Weather DataHub (Site Specific) leads on security \u0026 auth and transparency \u0026 trust.\n\n### Do Met Office Weather DataHub (Site Specific) and Meteosource Weather MCP need an API key?\n\nBoth need an API key.\n\n### Can an agent call Met Office Weather DataHub (Site Specific) and Meteosource Weather MCP without installing anything?\n\nYes. Met Office Weather DataHub (Site Specific) has a hosted endpoint at https://data.hub.api.metoffice.gov.uk/sitespecific/v0/point and Meteosource Weather MCP at https://mcp.meteosource.com/mcp.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/met-office-datahub-vs-meteosource-mcp.json, and with the fewest tokens: https://www.anchorterminal.com/compare/met-office-datahub-vs-meteosource-mcp.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"met-office-datahub\", \"b\": \"meteosource-mcp\"}`.
