Adafruit IO MCP by usefulapi

Adafruit IO MCP by usefulapi

Use Adafruit IO from Claude, Cursor, or any MCP client — IoT feeds, feed data and charts, groups, dashboards and activity, plus single data-point publishes. Hosted, no local install: connect with your own Adafruit IO credentials.

Live endpoint: https://adafruit-io.usefulapi.io/mcp · Homepage: https://usefulapi.io/adafruit-io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://adafruit-io.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http adafruit-io https://adafruit-io.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "adafruit-io": {
      "url": "https://adafruit-io.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Adafruit IO credentials.
