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 Bolt iot account to Claude via Composio Connect, enabling it to read temperature sensor value from pin A0, turn on relay connected to digital pin 1, check if device BOLT12345 is online now, 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 Bolt iot 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 Bolt iot account

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

For example, ask Claude to:

  • "Read temperature sensor value from pin A0"
  • "Turn on relay connected to digital pin 1"
  • "Check if device BOLT12345 is online now"

It will prompt you to authenticate and authorize access.

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

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

The Bolt iot MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Bolt IoT account. It provides structured and secure access to your connected IoT devices, so your agent can perform actions like reading sensor values, controlling actuators, checking device status, and managing UART communication on your behalf.

  • Real-time sensor data collection: Instantly retrieve analog sensor readings from any Bolt device for monitoring temperature, light, or other parameters.
  • Remote device control: Command your agent to switch actuators, toggle LEDs, or send digital signals to devices using digital write operations.
  • Device connectivity monitoring: Check if a specific Bolt IoT device is online before performing operations or troubleshooting connectivity issues automatically.
  • Serial communication management: Read incoming serial data or transmit ASCII commands over UART to interact with other hardware modules connected to your Bolt device.
  • Bidirectional UART automation: Send serial commands and immediately capture device responses in one seamless step, enabling complex automation workflows.

Troubleshooting

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

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

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

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

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

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

3. Why does the Bolt iot authorization link not work?

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

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

4. Why do Bolt iot actions fail after they worked before?

The Bolt iot connection can expire or lose permission.

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

5. How do I switch to a different Bolt iot account?

Claude can manage the Bolt iot connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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