Let AI install it

Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server AWS IoT Core for Claude on this computer, in this order: 1) Check uv with uv --version. If it is missing, tell me to install it from https://docs.astral.sh/uv/getting-started/installation/; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "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_REGION": "your-value" } } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) For AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, AWS_REGION, leave "your-value" in place and tell me to paste the real value myself into the file or the app’s field. Never ask me to type a key in chat. 5) Do what we agreed, then check that the AWS IoT Core tools really show up.

This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.

Common questions

Is AWS IoT Core safe?

It passed 3 of 3 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_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN

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 16 days ago, 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?

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.

Tools

Things (device registry)

Tool	Description
`list_things(thing_type_name, attribute_name, attribute_value, thing_group_name, max_results)`	List things, optionally filtered.
`search_things(query_string, index_name, max_results)`	Fleet-indexing search, e.g. `attributes.location:"lab-1"`. Requires indexing to be enabled.
`get_thing(thing_name)`	Fetch a thing's attributes and type.
`create_thing(thing_name, thing_type_name, attributes, billing_group_name, overwrite=False)`	Register a new thing.
`update_thing(thing_name, attributes, thing_type_name, remove_thing_type, attributes_merge=True)`	Update a thing's attributes/type.
`delete_thing(thing_name, confirm=False)`	Delete a thing. Irreversible.

Thing Types & Thing Groups

Tool	Description
`list_thing_types(thing_type_name)` / `get_thing_type(thing_type_name)`	List/read thing types.
`create_thing_type(thing_type_name, description, searchable_attributes)`	Create a thing type. Immutable once created (AWS limitation) — only deprecation is supported after.
`deprecate_thing_type(thing_type_name, undo=False)`	Deprecate (or un-deprecate) a thing type.
`list_thing_groups(parent_group, name_prefix_filter)` / `get_thing_group(thing_group_name)`	List/read thing groups.
`create_thing_group(thing_group_name, parent_group_name, attributes, overwrite=False)`	Create a thing group.
`delete_thing_group(thing_group_name, confirm=False)`	Delete a thing group. Irreversible.

`list_things_in_thing_group(thing_group_name)`	List members of a group.

Device Shadows (data plane)

Tool	Description
`get_thing_shadow(thing_name, shadow_name)`	Read a thing's shadow document (`desired`/`reported`/`delta`). Omit `shadow_name` for the classic (unnamed) shadow.
`update_thing_shadow(thing_name, desired, reported, shadow_name)`	Merge-update `desired` and/or `reported` state.
`delete_thing_shadow(thing_name, shadow_name, confirm=False)`	Delete a shadow document.
`list_named_shadows_for_thing(thing_name)`	List named (non-classic) shadows for a thing.

Messaging

Tool	Description
`publish_message(topic, payload, qos=0)`	Publish an MQTT message to the device fleet via the IoT Data Plane.

Jobs (fleet management)

Tool	Description
`list_jobs(status, thing_group_name, max_results)` / `get_job(job_id)`	List/read jobs.
`create_job(job_id, thing_arns, document, description, target_selection="SNAPSHOT")`	Create a fleet job (e.g. an OTA update or remote command).
`cancel_job(job_id, confirm=False, comment, force=False)`	Cancel a job.
`delete_job(job_id, confirm=False, force=False)`	Delete a job. Irreversible.
`list_job_executions_for_job(job_id, status)` / `list_job_executions_for_thing(thing_name, status)`	Track per-device execution status.

Certificates & Policies (device auth)

Tool	Description
`create_keys_and_certificate(set_as_active=True)`	Generate a new key pair + certificate. The private key is returned only once — capture it immediately.
`get_certificate(certificate_id)` / `list_certificates(page_size)`	Read certificate metadata.
`set_certificate_status(certificate_id, status)`	`ACTIVE`, `INACTIVE`, or `REVOKED`.
`delete_certificate(certificate_id, confirm=False, force_delete=False)`	Delete a certificate. Irreversible.
`create_policy(policy_name, policy_document, overwrite=False)` / `get_policy` / `list_policies`	Manage IAM-style IoT policies (JSON documents).
`delete_policy(policy_name, confirm=False)`	Delete a policy. Irreversible.
`modify_policy_attachment(policy_name, target, action)`	Attach/detach a policy to/from a certificate ARN.
`modify_thing_principal(thing_name, principal, action)`	Attach/detach a certificate (principal) to/from a thing.
`list_thing_principals(thing_name)` / `list_principal_things(principal)`	Look up thing↔certificate associations either direction.

Rules Engine

Tool	Description
`list_topic_rules(topic)` / `get_topic_rule(rule_name)`	List/read SQL-based message routing rules.
`put_topic_rule(rule_name, sql, actions, description, sql_version, overwrite=False)`	Create or replace a rule. `actions` is a list of raw AWS action objects (e.g. `{"lambda": {"functionArn": "..."}}`).
`set_topic_rule_enabled(rule_name, enabled)`	Enable/disable a rule without deleting it.
`delete_topic_rule(rule_name, confirm=False)`	Delete a rule. Irreversible.

Misc

Tool	Description
`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 var	Description
`AWS_ACCESS_KEY_ID` / `AWS_SECRET_ACCESS_KEY` / `AWS_SESSION_TOKEN`	Explicit credentials.
`AWS_PROFILE`	Named profile from `~/.aws/credentials`.
`AWS_REGION` / `AWS_DEFAULT_REGION`	Required — AWS IoT Core is regional.
`AWS_ENDPOINT_URL`	Override 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.
