Common questions

Is Azure IoT Hub 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: AZURE_IOT_HUB_CONNECTION_STRING

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 4 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?

Azure IoT Hub MCP Server

A Model Context Protocol (MCP) server for Azure IoT Hub — device registry, device twins, direct methods, jobs, and messaging.

Scoped to IoT Hub's service-side data plane (device management), not Azure Resource Manager. Microsoft's own official Azure MCP Server already covers the ARM-level "show me my IoT Hub resource" case — this server covers the actual device-management capability that Azure MCP doesn't.

Calls Azure IoT Hub's REST Service API directly via httpx with a hand-rolled SAS token generator, rather than the official azure-iot-hub PyPI package — that package hard-depends on uamqp, a C-extension that fails to build on modern Python/platforms (confirmed: it doesn't install on Python 3.12/arm64). Built with FastMCP.

Tools

Device registry

Tool	Description
`list_devices(max_count)`	List devices. For filtering, prefer `query_devices`.
`query_devices(query, max_item_count, continuation_token)`	IoT Hub SQL-like query over devices/twins, with pagination.
`get_device(device_id)`	Fetch a device's identity (auth mechanism, status, connection state).
`create_device(device_id, auth_type, ..., overwrite=False)`	Register a device.
`update_device(device_id, status, status_reason, etag)`	Update a device's enabled/disabled status.
`delete_device(device_id, confirm=False, etag)`	Delete a device. Irreversible.

Modules

Tool	Description
`list_modules(device_id)` / `get_module(device_id, module_id)`	List/read module identities on a device.
`create_module(device_id, module_id, ..., overwrite=False)`	Register a module.
`delete_module(device_id, module_id, confirm=False)`	Delete a module. Irreversible.

Device & module twins

Tool	Description
`get_device_twin(device_id)` / `get_module_twin(device_id, module_id)`	Read a twin (tags, desired/reported properties).
`update_device_twin(device_id, tags, desired_properties, etag)`	Merge-update tags/desired properties.
`replace_device_twin(device_id, tags, desired_properties, etag)`	Full replace (not merge) of tags/desired properties.
`update_module_twin(device_id, module_id, tags, desired_properties, etag)`	Merge-update a module twin.

Direct methods

Tool	Description
`invoke_device_method(device_id, method_name, payload, ...)`	Invoke a direct method on a device (blocks until the device responds or times out).
`invoke_module_method(device_id, module_id, method_name, payload, ...)`	Same, scoped to a module.

Jobs (fleet-scale operations)

Tool	Description
`create_scheduled_job(job_id, job_type, query_condition, ...)`	Schedule a twin update or direct method across many devices matching a query.
`get_scheduled_job(job_id)` / `query_scheduled_jobs(job_type, job_status)`	Read job status/results.
`cancel_scheduled_job(job_id, confirm=False)`	Cancel a job.

Messaging

Tool	Description
`send_c2d_message(device_id, payload, ...)`	Send a cloud-to-device message. AMQP, not REST — see caveat below.
`purge_c2d_message_queue(device_id)`	Delete all pending C2D messages queued for a device.

Statistics

Tool	Description
`get_device_statistics()`	Total/enabled/disabled device counts.
`get_service_statistics()`	Service-level stats (e.g. connected device count).

Important caveat: `send_c2d_message` is AMQP, not REST, and has no real-instance test coverage

Every other tool in this server wraps a documented REST endpoint. Cloud-to-device message sending is the one exception: Azure IoT Hub's REST API only exposes the *feedback* side of C2D messaging (delivery receipts); sending is AMQP-protocol-only (confirmed by reading the official azure-iot-hub SDK's source — it hands off to an AMQP client, not an HTTP call).

To support it without pulling in the broken uamqp dependency, send_c2d_message implements the CBS (Claims-Based Security) auth handshake and message send directly against python-qpid-proton (the standard AMQP 1.0 library, confirmed to install cleanly on modern Python). The protocol details (CBS field names, $cbs node, /messages/devicebound target address, to property format) were confirmed from Microsoft's own pure-Python AMQP implementation in azure-eventhub/azure-servicebus, not guessed.

This tool is not covered by real-instance testing. There's no free Azure IoT Hub emulator (see Testing below), and the test suite's respx HTTP mocking can't exercise AMQP at all. Tests instead run this against a local fake AMQP endpoint (also built with qpid-proton) that implements just enough of the CBS handshake and /messages/devicebound receiver to prove the wire protocol is well-formed — it does not validate genuine Azure IoT Hub business logic. Verify against a real hub before relying on this in production.

Safety conventions

Same as the rest of this repo: create_* defaults to overwrite=False (best-effort describe-then-create check — IoT Hub's If-Match header is for optimistic-concurrency on updates, not create-only semantics, so this isn't fully race-free like Ditto's If-None-Match). Every delete_*/cancel_* requires confirm=True.

Configuration

Env var	Required	Description
`AZURE_IOT_HUB_CONNECTION_STRING`	Yes	An IoT Hub connection string with `service` (or `iothubowner`) rights, e.g. `HostName=my-hub.azure-devices.net;SharedAccessKeyName=service;SharedAccessKey=...`. Find this under your hub's "Shared access policies" in the Azure portal.
`AZURE_IOT_HUB_AMQP_PORT`	No	Default `5671`. Only relevant to `send_c2d_message`.
`AZURE_IOT_HUB_AMQP_USE_TLS`	No	`true`/`false`, default `true`. Set `false` only for local/test endpoints.
`AZURE_IOT_HUB_AMQP_HOSTNAME_OVERRIDE`	No	Override the AMQP connection target (e.g. a local test fixture) without changing the REST hostname derived from the connection string.

Running locally

uv sync

export AZURE_IOT_HUB_CONNECTION_STRING="HostName=my-hub.azure-devices.net;SharedAccessKeyName=service;SharedAccessKey=..." uv run azureiothubmcpserver.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. Azure IoT Hub has no official local emulator and no moto-equivalent exists for it. REST endpoints are tested with respx (httpx's dedicated mocking library, using realistic Azure response shapes); send_c2d_message is tested against a local fake AMQP endpoint (see caveat above).

uv run pytest -v

License notes

No bundled deployment artifacts here (unlike eclipse-ditto/mqtt) since there's no local broker/service to run — Azure IoT Hub only exists as an Azure-hosted service.
