What is the Weather Edge MCP MCP server?

If you already use Weather Edge MCP, the weather edge mcp mcp server is the piece that lets your assistant work with it directly. Weather Edge is an MCP server for calibrated Kalshi weather-market signals. It turns public forecast and market data into a compact tool surface for AI agents.

What the server does

  • calibrates NWS daily high-temperature forecasts by city
  • reads current Kalshi weather market prices
  • estimates per-bucket probability, edge, and net expected value
  • exposes the results through MCP tools and an optional FastAPI surface

Installation

Installation goes through your MCP client rather than a global install: point it at weather-edge-mcp on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

Where it fits

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by rjw34; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
