Overview

Description from the maker (original English)

MCP server for AWS IoT Core: device registry, shadows, jobs, rules, messaging.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Developer tools
  • You need to fill in: AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, AWS_REGION

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, AWS_PROFILE, AWS_REGION

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • PyPIPython’s uv installed (for the uvx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "aws-iot-core": {
      "command": "uvx",
      "args": [
        "aws-iot-core-mcp-server"
      ],
      "env": {
        "AWS_ACCESS_KEY_ID": "your-value",
        "AWS_SECRET_ACCESS_KEY": "your-value",
        "AWS_SESSION_TOKEN": "your-value",
        "AWS_PROFILE": "your-value",
        "AWS_REGION": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add aws-iot-core --env AWS_ACCESS_KEY_ID=your-value --env AWS_SECRET_ACCESS_KEY=your-value --env AWS_SESSION_TOKEN=your-value --env AWS_PROFILE=your-value --env AWS_REGION=your-value -- uvx aws-iot-core-mcp-server

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "aws-iot-core": {
      "command": "uvx",
      "args": [
        "aws-iot-core-mcp-server"
      ],
      "env": {
        "AWS_ACCESS_KEY_ID": "your-value",
        "AWS_SECRET_ACCESS_KEY": "your-value",
        "AWS_SESSION_TOKEN": "your-value",
        "AWS_PROFILE": "your-value",
        "AWS_REGION": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "aws-iot-core": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "aws-iot-core-mcp-server"
      ],
      "env": {
        "AWS_ACCESS_KEY_ID": "your-value",
        "AWS_SECRET_ACCESS_KEY": "your-value",
        "AWS_SESSION_TOKEN": "your-value",
        "AWS_PROFILE": "your-value",
        "AWS_REGION": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • AWS_ACCESS_KEY_ID env
    AWS access key ID
  • AWS_SECRET_ACCESS_KEY secret env
    AWS secret access key
  • AWS_SESSION_TOKEN secret env
    AWS session token, for temporary credentials
  • AWS_PROFILE env
    Named profile from ~/.aws/credentials, as an alternative to explicit keys
  • AWS_REGION required env
    AWS region -- required, AWS IoT Core is regional

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is AWS IoT Core safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, AWS_REGION

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

AWS IoT Core MCP Server

A Model Context Protocol (MCP) server for AWS IoT Core — device registry, device shadows, jobs (fleet management), the rules engine, and messaging.

Scoped deliberately to IoT Core itself: no Greengrass (separate edge-deployment API), no IoT SiteWise (already has an official awslabs MCP server), no Device Defender/Events/TwinMaker — each of those is its own AWS service with its own API and would be its own connector.

Built with FastMCP and boto3.

Misc
ToolDescription
get_endpoint(endpoint_type)Look up this account's IoT Core data endpoint (default iot:Data-ATS).

Safety conventions

Same as the rest of this repo: create_*/put_* default to overwrite=False (best-effort — the AWS IoT API itself has no conditional-write header for most of these operations, so this is a describe-then-create check, not fully race-free like Ditto's If-None-Match). Every delete_*/cancel_* requires confirm=True.

Configuration

Standard AWS SDK credential resolution — no custom env vars for auth. Set whichever of these your setup uses:

Env varDescription
AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY / AWS_SESSION_TOKENExplicit credentials.
AWS_PROFILENamed profile from ~/.aws/credentials.
AWS_REGION / AWS_DEFAULT_REGIONRequired — AWS IoT Core is regional.
AWS_ENDPOINT_URLOverride the API endpoint (e.g. for LocalStack). boto3 reads this natively.

Or an IAM role, if running somewhere with one attached (EC2/ECS/Lambda). See boto3's credential docs.

Running locally

uv sync

export AWS_REGION=us-east-1

plus whichever credential env vars apply to you

uv run awsiotcoremcpserver.py

See mcp.json for ready-to-use client configs (stdio and Docker).

Testing

This repo's design principles call for testing against a real instance rather than mocks. AWS IoT Core has no official local emulator, and LocalStack's IoT support requires a paid plan (no free tier) — so this server is the one exception in this repo: tests run against moto, a mature, free, open-source AWS API emulator (not hand-rolled mocks — it implements real request/response behavior for the actual boto3 calls this server makes).

uv run pytest -v

License notes

No bundled deployment artifacts here (unlike the other servers) since there's no local broker/service to run — AWS IoT Core only exists as an AWS-hosted service.
