Ask Claude About Pollen — Free Pollen Forecasts in Claude

Ask Claude what's the pollen in Oslo today and, until last week, you'd get a polite hedge: 'I don't have access to real-time pollen data.' That's no longer true. Atmospore is now connected to Claude (and any MCP-compatible AI assistant — Cursor, Continue, ChatGPT Desktop). Ask in plain language, get charts, forecasts, and personal advice in seconds.

Claude conversation showing birch pollen levels across Scandinavia with bar chart, 6-day forecast, and written summary — A real conversation. We asked Claude for Scandinavian birch levels — it returned a ranked chart, a six-day forecast, and a plain-language summary, all in a single answer.

What you can ask

Some questions that work well today:

“What's the pollen in Oslo today?”

“I'm allergic to birch and oak. I'm travelling to Stockholm next week — which days should I stay indoors?”

“Compare birch levels across Scandinavia and tell me where it's worst.”

“Has the grass pollen peaked yet in Berlin, or is the worst still ahead?”

Claude conversation answering 'I'm allergic to birch and oak, travelling to Stockholm next week — which days should I stay indoors?' with worst-day highlights, color-coded chart, and daily recommendations table. — Same MCP, different question. Claude turned a travel-and-allergy question into highlight cards (worst day, second worst, best of a bad week), a colour-coded chart, and a daily action plan with mask-or-stay-indoors recommendations.

Two-minute setup

Nothing to download. You need Claude Desktop and a free Atmospore API key (100 questions per day, no credit card). Then paste this into your Claude Desktop config:

{
  "mcpServers": {
    "atmospore": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.atmospore.com/mcp",
        "--header",
        "Authorization: Bearer atmo_your_key_here"
      ]
    }
  }
}

Restart Claude. That's the whole setup. Now ask anything about pollen the way you would ask a friend who happens to be a meteorologist.

Why this beats opening another app

Pollen apps tell you a number. Claude with Atmospore plans your week. Ask about three cities at once and get a side-by-side comparison. Mention which species you're allergic to and the answer ignores everything else. Follow up with 'is the trend getting worse?' and the same conversation answers in context.

Behind the scenes, Claude calls our forecast service the moment you ask. No browsing, no copy-paste, no opening another app. The data covers any point on Earth — every grid cell on the planet, twenty-one species of pollen, seven days ahead.

Try it
