Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to usefulapi.io, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Hosted MCP server for Adafruit IO that lets an assistant read IoT feeds, data points, groups and dashboards, and publish a value or create a feed.

What you can do: Inspect the account: user profile, data rate limit, activity log.
Browse feeds: list, get details, last value and stored point counts.
Query feed data: recent points, single points by id, and aggregated chart series by resolution and time range.
Explore groups and dashboards, including dashboard blocks and their feeds.
Write: publish one data point to a feed, or create a new empty feed.
When to use it: Useful when you want to ask questions about sensor or device data held in Adafruit IO, summarize trends over a time window, or push a single value to a feed that drives hardware. It suits hobbyist and small IoT setups rather than bulk data pipelines.
Requirements: Remote endpoint reached over streamable HTTP; no local install. Sign-in is by OAuth, and the login page asks for your Adafruit IO credentials. Add only the server URL to the client config, not an API key or Authorization header. A free tier allows 50 tool calls per month; paid plans raise the limit.

Before you install

Publishing a data point can drive real devices subscribed to the feed (relays, motors, lights, heaters, locks) and cannot be undone from here; only publish values the user asked for. Write tools change Adafruit IO data. The service meters tool calls and offers paid plans with payment links, so upgrades involve spending money. Your Adafruit IO credentials are entered on the hosted login page.

Installation

In SourceWeft

Open Adafruit IO MCP by usefulapi in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Fadafruit-io/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

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:

json

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

{  "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.

The Adafruit IO account this key belongs to: id, name, username, time zone, created/updated times, plus the data rate limit when reported. GET /api/v2/user.

Takes no parameters.

adafruitio_get_throttle

Get data rate limit

The account's data rate limit (data-record modifications per minute: 30 on free accounts, 60 on Plus) and the current active data rate. Check it before publishing many points. GET /api/v2/{username}/throttle.

Takes no parameters.

adafruitio_list_feeds

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
