Api Key

Adafruit IO is Adafruit's cloud platform for connected device and IoT project data. It helps you store, visualize, and act on sensor feeds without running your own backend.

21 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 Adafruit IO account to Claude via Composio Connect, enabling it to summarize temperature feed anomalies today, publish humidity reading to greenhouse feed, list recent door sensor events, 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 Adafruit 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 Adafruit IO account

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

For example, ask Claude to:

  • "Summarize temperature feed anomalies today"
  • "Publish humidity reading to greenhouse feed"
  • "List recent door sensor events"

It will prompt you to authenticate and authorize access.

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

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

The Adafruit 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 Adafruit IO account. It provides structured and secure access so your agent can perform Adafruit IO operations on your behalf.

Troubleshooting

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

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

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

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

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Adafruit 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 Adafruit IO.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Adafruit IO authorization link not work?

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

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

4. Why do Adafruit IO actions fail after they worked before?

The Adafruit IO connection can expire or lose permission.

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

5. How do I switch to a different Adafruit IO account?

Claude can manage the Adafruit IO connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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