Anecast answers the questions a plain forecast can't: what's unusual about today, what changed since yesterday, why (the NWS forecaster's own reasoning), and how today compares to decades of station history — plus the forecast itself, with the active watches and warnings generic weather tools omit.
Remote MCP endpoint (Streamable HTTP, no authentication):
https://www.anecast.app/mcp
| From | How |
|---|---|
| Claude (claude.ai, desktop, mobile) | One click from the Claude directory — or Settings → Connectors → Add custom connector → paste the URL. All plans. |
| Claude Code | claude mcp add --transport http anecast https://www.anecast.app/mcp |
| Cursor, Windsurf, any MCP client | Add a remote server with type streamable-http (or http) and the URL above. |
| Claude API | Pass it in mcp_servers on a Messages request: {"type": "url", "url": "https://www.anecast.app/mcp", "name": "anecast"} |
| Anything else | It's plain JSON-RPC over POST — curl -X POST https://www.anecast.app/mcp -H 'Content-Type: application/json' -H 'Accept: application/json, text/event-stream' -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}' |

A — roster cities: full snapshot history, daily editorial notes. B — enrolled gridpoints: someone asked before; change-tracking has been accruing since. C — first touch: live forecast and reasoning immediately; the snapshot tape starts with your question, and the response says so. Asking about a place upgrades its coverage — that's the design.
