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 Stormglass io account to Claude via Composio Connect, enabling it to fetch today's marine weather for Miami, get solar irradiation for a specific location, list all tide stations near San Francisco, 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 Stormglass io 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 Stormglass io account

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

For example, ask Claude to:

  • "Fetch today's marine weather for Miami"
  • "Get solar irradiation for a specific location"
  • "List all tide stations near San Francisco"

It will prompt you to authenticate and authorize access.

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

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

The Stormglass io MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Stormglass io account. It provides structured and secure access to global high-resolution weather and environmental data, so your agent can perform actions like fetching marine forecasts, retrieving solar data, listing tide stations, and getting elevation information for any location on your behalf.

  • Marine and land weather retrieval: Instantly fetch detailed weather forecasts or historical weather data for any geographic coordinates, including temperature, wind, and wave conditions.
  • Solar irradiation and sun-position analysis: Have your agent provide solar data—like irradiation levels and sun angles—for specific points and time ranges, ideal for planning solar projects or outdoor activities.
  • Elevation and bathymetry lookup: Quickly obtain elevation or sea depth information for any latitude and longitude, supporting both topography and bathymetry use cases.
  • Tide station cataloging: Let your agent list all available tide stations worldwide, making it easy to select stations for further tidal or marine data queries.

Troubleshooting

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

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

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

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

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

  • 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 Stormglass io.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Stormglass io authorization link not work?

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

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

4. Why do Stormglass io actions fail after they worked before?

The Stormglass io connection can expire or lose permission.

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

5. How do I switch to a different Stormglass io account?

Claude can manage the Stormglass io connection for you.

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

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

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

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Stormglass io 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 Stormglass io.

FAQ

Frequently asked questions

With a standalone Stormglass io MCP server, the agents and LLMs can only access a fixed set of Stormglass io tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Stormglass io 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 Stormglass io tools.

Yes, absolutely. You can configure which Stormglass io 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 Stormglass io data and credentials are handled as safely as possible.
