What the publisher says

From the AWS IoT Core repository's README, as published. We do not edit it. Read it on GitHub

IoT MCP Servers

MCP (Model Context Protocol) servers for IoT platforms — giving AI agents full read/write access to device registries, digital twins, and telemetry.

Servers

Each row links to that server's README for its full tool list, required environment variables, and setup/testing notes.

Structure

Each server is a standalone directory under this repo — its own pyproject.toml, uv.lock, Dockerfile, and mcp.json example config. No shared library layer: every server is independently runnable and dockerizable.

<server-name>/
├── <server-name>mcpserver.py   # FastMCP server (single file)
├── pyproject.toml              # own dependencies
├── uv.lock
├── Dockerfile
├── mcp.json                    # example MCP client config
└── README.md                   # tools, env vars, setup for this server

Requirements

  • Python 3.12+
  • uv for dependency management and running servers
  • Docker, only if you want to run a server's own test suite against a real/emulated instance (see that server's README)

Quick start

Install straight from PyPI with uv or pipx — no clone needed:

uvx eclipse-ditto-mcp-server      # or: mqtt5-mcp-server / aws-iot-core-mcp-server / azure-iot-hub-mcp-server / sparkplug-b-mcp-server

Or run from a clone of this repo:

git clone https://github.com/nagarjunr/iot-mcp-servers.git
cd iot-mcp-servers/<server-name>
uv sync
uv run <server-name>mcpserver.py

Each server reads its configuration from environment variables (connection strings, broker host, credentials, etc.) — see that server's README for the full list.

Using with an MCP client

Shortened. The full README is on GitHub.

AWS IoT Core: common questions

Is AWS IoT Core MCP server safe?
Mostly: it is graded B (78/100). Read the AWS IoT Core safety report
How do I install AWS IoT Core?
It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.
Does AWS IoT Core need an API key?
Yes. The registry entry asks for AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN.
Is AWS IoT Core maintained?
The last commit was 90 days ago (2026-08-04). The latest release is v0.1.0.
What can I use instead of AWS IoT Core?
Servers from other publishers that do the same job: TerraVision MCP server, cloud-audit MCP server and Cloud FinOps Skill & MCP server.
How does AWS IoT Core compare with other Developer tools MCP servers?
safety score 78/100 (higher than 50% of 1,119 Developer tools servers); tools 48 (the typical Developer tools server has 7); tools that change things 40% (typical: 5%. Fewer write tools means less an agent can break). Full comparison.
