MCP support
This remote MCP server provides global historical weather and climate queries to MCP clients. It uses Streamable HTTP and OAuth 2.0 PKCE authentication.

From the project READMEWeathersight MCP Connector
Connect Claude — or any MCP client — to Weathersight: 100+ years of station observations, typical-weather climatology, anomalies, extremes, degree days, and long-term climate trends for locations worldwide.
This is a remote MCP server. There is nothing to install.
https://weathersight.io/api/mcp
Connect
Claude (Desktop or web)
- Settings → Connectors → Add custom connector
- URL:
https://weathersight.io/api/mcp - Connect, then sign in when prompted
Signing in creates your Weathersight API token automatically if you don't already have one, and starts a free trial. Existing token holders keep the token they already have.
Other MCP clients
Point the client at the same URL. The server speaks Streamable HTTP (spec 2025-03-26) and authenticates with OAuth 2.0 authorization-code + PKCE, including dynamic client registration — no manual credential setup.
What you can ask
- "What's the typical weather in Reykjavik in late September?"
- "Has Bengaluru's monsoon onset shifted over the last 40 years?"
- "Which US cities broke heat records last week?"
- "Compare this July in Madrid to its 1991–2020 baseline."
Managing your connection
- Your token and plan: https://weathersight.io/subscription
- API reference: https://weathersight.io/docs
If the connector stops returning data, your client will usually prompt you to sign in again. If it reports that your plan has lapsed, visit the subscription page above — the connector and token resume working once a plan is active.
About this repository
This repo is the public home of Weathersight's MCP Registry
entry. server.json is the metadata record that tells the registry — and the
directories that mirror it — what this server is called, where it lives, and how to reach it.
The connector itself is served from the Weathersight application.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
