What is azure-iothub-service?

A workflow for operating Microsoft Azure IoT Hub through a connected MCP server. Azure IoT Hub is Microsoft’s service for connecting to and managing Internet of Things devices.

Sending messages or direct commands to devices, reading or updating device twin information, managing devices, and handling IoT Hub jobs when the required hub scope is configured.

It gives the agent defined procedures for reading and changing device information while requiring real device data and confirmation for destructive actions.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00158	$0.02652
Opus 5.5	$0.00063	$0.01061
Sonnet 5.5	$0.00032	$0.00530
Haiku 4.5	$0.00016	$0.00265

Security

Grade A, and why

azure-iothub-service scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Azure IoT Hub Skill

Operate Azure IoT Hub end-to-end via the azure-iothub-service-mcp MCP Server. This skill covers five capability areas — read the relevant section before acting.

General Principles
C2D Direct Methods (Commands)
C2D Messages
Device Twin — Tags & Reported Properties
Device Management
IoT Hub Jobs
Error Handling & Retry Guidance
Query Cheat-Sheet

1. General Principles

Never fabricate device data. Always call an MCP tool and surface the real result to the user.
Confirm destructive operations (delete, disable, rotate keys) with the user before executing, unless the user has already confirmed in their message.
Scope awareness: Ask the user for the IoT Hub name / connection scope if it is not already established in the conversation or pre-configured in the MCP server.
Pagination: Device queries and job listings may be paginated. Loop with continuationToken until exhausted, or ask the user how many records they want.
Present results clearly: Format twin documents as collapsible JSON blocks; format device lists as tables with columns deviceId | status | lastActivityTime.
Use the right tool for the job: For commands needing a response, use Direct Methods. For fire-and-forget notifications, use C2D messages. For fleet-wide updates, use Jobs.
Jobs: Use jobs ONLY if the user requests explicitly mentioning the key word "job".

2. C2D Direct Methods (Commands)

Direct methods are synchronous RPC calls to a connected device. Use them for real-time commands (reboot, firmware update trigger, valve open/close, etc.).

Workflow

Confirm deviceId (or a list of deviceIds) and methodName with the user.
Build the payload from the user's instructions.
Call the tool.
Show the response: status code + payload returned by the device.
If status is not 200, surface the error and suggest checking device connectivity.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
