How to integrate Stormglass io MCP with Hermes

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows. This guide explains the easiest and most robust way to connect your Stormglass io account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

What is Composio Connect?

Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness — including Hermes. It can:

  • Search and load tools from relevant toolkits on-demand, reducing context usage.
  • Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
  • Manage app authentication end-to-end with zero manual overhead.

Integrating Stormglass io with Hermes

Using Composio Connect CLI

1. Install the Composio CLI

Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

bash
curl -fsSL https://composio.dev/install | bash
Hermes authenticating with Composio

2. Authenticate

Once the CLI is installed, ask Hermes to authenticate with Composio.

3. Connect to Stormglass io

Ask your agent to connect to Stormglass io, or simply request any Stormglass io-related task. Hermes will prompt you to authenticate and authorize access.

4. Done. You're all set with a new Stormglass io connection.


Using Composio Connect MCP

1. Get your MCP URL and API Key

Go to dashboard.composio.dev and copy your Connect MCP URL and API key.

Copy MCP URL and API key from Composio dashboard

2. Open the Hermes config file

bash
nano ~/.hermes/config.yaml

3. Add the Composio Connect MCP server

bash
mcp_servers:
  composio:
    url: "https://connect.composio.dev/mcp"
    headers:
      x-consumer-api-key: "YOUR_COMPOSIO_API_KEY"
    connect_timeout: 60
    timeout: 180

Save with Ctrl + O, Enter, then exit with Ctrl + X.

4. Restart your Hermes agent

Once restarted, ask your agent to connect to Stormglass io or request any Stormglass io-related task. It will prompt you to authenticate and authorize access.

5. Done!

What is the Stormglass io MCP server, 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.

Way Forward

With Stormglass io connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.

From here, you can extend Hermes further:

  • Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
  • Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
  • Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

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. Hermes 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.
