🌦️ MeteoSwiss LLM Tools

Swiss weather data for AI assistants — powered by MeteoSwiss Open Data, the same data behind the MeteoSwiss app and website. Free, no API key required.

meteoswiss-mcp.ars.is — try the hosted service instantly, no setup needed.

• Multi-day forecasts for ~6000 Swiss locations (postal codes, stations, place names)
• Real-time measurements from ~160 automatic weather stations, updated every 10 minutes
• Station discovery by name, canton, or GPS coordinates
• Pollen monitoring from ~15 stations across Switzerland
• MeteoSwiss website search and content retrieval

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.
