# Weather Markets Edge Desk

An MCP server for Kalshi weather markets: the daily-high board next to the NWS forecast, live edges, EV and Kelly sizing.

## What it does

A hosted MCP server that hands your agent the weather side of Kalshi. Seven tools sit behind it: `weather_board` lists every open daily-high strike, `edge_alerts` streams weather signals, and five calculators round it out. The NWS forecast sits beside the market price, so you can see where the two disagree.

You don't compute anything yourself. Expected value, Kelly position size and base rates come back from the server. Setup is one command against a remote endpoint, no package to install, and this surface needs no API key.

It only works online. The same package ships a `--local` build with six calculators that makes no network calls, though it won't serve the weather board. Hosts that speak stdio only need the `npx` bridge.

## Requirements

## When to use it
- compare the NWS forecast against the daily-high price
- list open Kalshi weather strikes
- work out EV and Kelly position size
- spot where forecast and market diverge
- check the base rate on a weather event

## Example prompts
- Show me the Kalshi weather board and which daily-high strikes are open
- Compare the NWS forecast with the market price and tell me where the edge is
- Size this strike with Kelly and give me the EV
