Weathermap is a visual weather data and forecasting platform. It helps users understand climate patterns and track severe weather conditions effectively.

2 Tools

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Weathermap account to Claude via Composio Connect, enabling it to show current weather for Paris, France, give me tomorrow’s forecast in Tokyo, map severe storms near your location, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

Connecting Weathermap to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Weathermap account

Back in Claude, ask it to connect to Weathermap or give it any Weathermap-related task.

For example, ask Claude to:

  • "Show current weather for Paris, France"
  • "Give me tomorrow’s forecast in Tokyo"
  • "Map severe storms near your location"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Weathermap account is ready to use.

What is the Weathermap Claude Connector, and what's possible with it?

The Weathermap MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to visual weather data and forecasts. It provides structured and secure access to real-time and forecasted weather information, so your agent can perform actions like retrieving current conditions, visualizing climate trends, tracking severe weather, and generating weather maps on your behalf.

  • Current weather lookups: Instantly ask your agent to fetch up-to-date weather conditions for any city or geographic location worldwide.
  • Forecast generation: Let your agent provide detailed weather forecasts—hourly, daily, or multi-day—for planning ahead or staying informed.
  • Severe weather tracking: Enable your agent to monitor and alert you about severe weather patterns, storms, or climate warnings in specific areas.
  • Visual weather mapping: Have your agent generate and display visual weather maps, including precipitation, temperature, and wind overlays for better situational awareness.
  • Climate data queries: Request climate trends and patterns for custom regions to support research, reporting, or travel planning.

Troubleshooting

1. Why does Claude not use the Composio connector for Weathermap?

The connector can show as connected, but Claude must use it in each Weathermap conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Weathermap again.

2. Why does Claude show an MCP server error before Weathermap connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Weathermap.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Weathermap.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Weathermap authorization link not work?

The Composio connector is one server. Your Weathermap account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Weathermap connection.
  • Composio creates a fresh Weathermap authorization link.
  • Open that link in your browser and finish the Weathermap sign-in.

4. Why do Weathermap actions fail after they worked before?

The Weathermap connection can expire or lose permission.

  • Ask Claude to inspect the Weathermap connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Weathermap account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Weathermap.
  • If the action still fails with a permission error, check that the connected account has that permission in Weathermap itself.

5. How do I switch to a different Weathermap account?

Claude can manage the Weathermap connection for you.

  • Ask Claude to disconnect or delete the current Weathermap account.
  • Ask Claude to connect Weathermap again.
  • Open the new Composio authorization link for Weathermap.
  • Sign in with the other Weathermap account in the browser.
  • After the account connects, ask Claude to retry the Weathermap task.

6. Why is my Weathermap connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Weathermap connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Weathermap tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Weathermap.

FAQ

Frequently asked questions

With a standalone Weathermap MCP server, the agents and LLMs can only access a fixed set of Weathermap tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Weathermap and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Weathermap tools.

Yes, absolutely. You can configure which Weathermap scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Weathermap data and credentials are handled as safely as possible.
