// tools this server exposes19 tools

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

get_entity_list

Retrieves a summarized list of all Home Assistant entities (includes entity_id, state, and friendly_name). Use this to quickly discover available entities.

get_entity_details

Retrieves full details (attributes, context, states) for specific entity IDs. Call this when you need detailed properties of specific sensors/devices.

search_entities

Filters and searches entities by area, domain, or string query.

get_services

Returns all available Home Assistant service domains, operations, and parameter schemas.

call_service

Triggers a service call in Home Assistant (e.g., toggling a light, announcing a TTS message on a speaker, setting temperature).

read_ha_file

Reads a configuration file (like configuration.yaml or a dashboard YAML file) from the sandboxed configuration directory.

write_ha_file

Writes/modifies a configuration file in the sandboxed configuration directory. For YAML files, this automatically lints the syntax, takes a backup, validates configuration against HA core, and rolls back if check_config fails.

render_template

Renders a Jinja2 template string using Home Assistant template rendering engine. Excellent for testing state query calculations or formatting speech output.

get_history

Fetches historical state changes for specific entity IDs starting from a timestamp.

get_automation_traces

Retrieves a list of recent execution traces for a specific automation ID.

get_automation_trace_details

Fetches detailed execution step data for a specific automation run ID.

validate_ha_config

Triggers the Home Assistant configuration check endpoint to verify configuration validity.

reload_ha

Reloads core configuration, templates, scripts, helpers, and automations without restarting Home Assistant core.

restart_ha

Restarts the Home Assistant core instance. Use with caution.

get_ha_logs

Retrieve the latest Home Assistant core logs from home-assistant.log.

manage_lovelace_resources

List, create, update, or delete Lovelace dashboard resources (custom cards, themes, modules). Bumping url query params (e.g. ?v=1.0.1) forces browsers to refresh their caches.

execute_host_command

Executes an arbitrary shell command on the Home Assistant host (SSH mode only). Use this to check host processes, disk usage, or run network diagnostics.

manage_helpers

Create, list, update, or delete Home Assistant input helpers (input_boolean, input_number, input_select, input_text, input_datetime, counter, timer) via the WebSocket API. No YAML editing or reload required.

get_registry

Query the Home Assistant entity, device, or area registries for detailed metadata not available in entity states (e.g. device manufacturers, model names, area assignments, disabled entities, device IPs).

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

19/19 tools missing one or more hints — get_entity_list (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_entity_details (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_entities (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +16 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

License file

No license file

Add a LICENSE file (MIT, Apache-2.0, etc.).

Tests exist

No test files found

Add tests that exercise each declared tool.

Shell command execution

6 child_process calls — runs shell commands

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Production dependencies are patched

0 critical, 2 high severity in production deps — @modelcontextprotocol/sdk@0.6.0 (high), ws@8.18.0 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 6 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
