Choose Your Approach

This monorepo offers two ways to bring Swiss weather data into AI assistants:

MCP Server Agent Skill
How it works Standalone server exposing structured tools via MCP Teaches agents to call MeteoSwiss APIs directly via HTTP
Best for Claude Desktop, Claude.ai, any MCP client Claude Code, Cursor, agents without MCP support
Features Fuzzy station matching, geocoding, structured JSON, prompts Lightweight, no server process, shell scripts included
Install One-liner or Docker Skill package or symlink
Requires Node.js 22+ (or Docker) curl, awk, jq

MCP Server — Quickstart

Use the hosted instance (no installation):

# Claude Code
claude mcp add meteoswiss https://meteoswiss-mcp.ars.is/mcp

For Cursor, install from the Cursor Directory or add manually via Settings → MCP.

Or self-host with Docker:

docker run -p 3000:3000 ghcr.io/eins78/meteoswiss-mcp:latest

See the meteoswiss-mcp README for Claude Desktop setup, environment variables, and full documentation.

Agent Skill — Quickstart

Install via the Claude Code plugin marketplace:

/plugin marketplace add eins78/meteoswiss-llm-tools
/plugin install meteoswiss-skills@meteoswiss-marketplace

Or with the Skills CLI:

pnpx skills add https://github.com/eins78/meteoswiss-llm-tools.git#packages/meteoswiss-skills --global --agent claude-code --all

See the meteoswiss-skills README for manual installation and details.
