Adafruit IO for AI agents

Adafruit IO is a cloud platform for storing, visualizing and acting on data from connected hardware projects. Makers and IoT developers use it to log sensor data and drive dashboards. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

01 · USE CASES

What agents do in Adafruit IO.

01

Check the latest data point

Read the most recent value reported by a connected sensor feed before deciding on next steps.

02

Publish data to a feed

Send a new value to a feed, such as toggling a device or logging a sensor reading.

03

Delete a data point

Remove a specific reading from a feed's history, a destructive action worth confirming before it's gone.

02 · ACTIONS

21 Adafruit IO actions, graded by risk.

Every Adafruit IO action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

03 · HOW IT WORKS

Adafruit IO in three steps.

  1. 01Your users connect Adafruit IOThey add their Adafruit IO api key on Arc0 Connect, under your brand. It goes straight into the vault.
  2. 02You set the rulesReads run, writes like “create Feed” can wait for the user, and “delete Feed” can be denied outright.
  3. 03Any agent can actYour agent calls Adafruit IO through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
POLICY.TS
await arc0.policies.set('adafruit_io', {
  read: 'allow',
  write: 'ask',        // create_feed
  destructive: 'deny',  // delete_feed
})

# Claude Code: the same connection, one URL

04 · AUTH AND DATA

How Adafruit IO connects.

Users add their Adafruit IO api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same Adafruit IO connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Adafruit IO and Arc0, answered.

Q01

Can I use Adafruit IO with Claude, ChatGPT or Cursor?

Yes. Connect Adafruit IO to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Adafruit IO actions you allow.

Q02

How do users connect Adafruit IO?

Users add their Adafruit IO api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which Adafruit IO actions can my agent take?

21 in total: 6 read, 9 write and 6 destructive, such as “create Feed”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Adafruit IO?

Yes. Actions like “delete Feed” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Adafruit IO too?

Yes. The same Adafruit IO connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
