Zapier Smart Home MCP. Control every smart device with simple English commands.

Listen up. This isn't some fancy, overhyped 'AI assistant.' This is what you need: full, direct control over every damn thing connected in your smart house using nothing but plain English commands. Your agent talks directly to Zapier’s massive API, letting you treat your whole setup like it's one giant system.

If you want to run a specific action—say, 'turn on the kitchen light' or 'set the temperature to 70 degrees'—you use execute_zapier_action. You first need to identify that action by its unique ID; once you have it, this tool runs the command instantly.

For general smart functions across thousands of apps, start with list_smarthome_actions. It pulls up a list of about fifty possible actions, letting you see everything the system knows how to handle right now. If you don't know what action ID you need yet, just send a plain English command using send_natural_language_command.

Zapier’s engine automatically figures out where that command belongs and routes it to the correct device integration without you needing to specify a tool first.

If you're building something complex or want to know what actions are even available, run through these discovery tools. You can use list_exposed_actions to see every single action your AI client is allowed to touch within your Zapier account right now. Want to check if there are any climate controls? Call list_climate_actions.

It shows you all the specific actions for thermostats and heating/cooling settings before you change a thing. Similarly, for lights, running list_lighting_actions gives you every option—turning them on or off, adjusting dimness, or changing colors.

Security is another one. If you need to manage locks, cameras, or alarms, the tool you want is list_security_actions. It pulls up all available actions related to securing your place, like locking doors or managing alarm status.

Need to find out what’s possible across 5000+ apps? Use search_zapier_actions and type in natural language. It searches the whole catalog for relevant functions that match your intent. To see if there are any specific actions available at all, run list_ai_zaps; this shows you every automation workflow (Zap) that was built using AI.

When it comes to routines—the big multi-step stuff—you don't have to guess. You can use preview_zapier_zap and just describe the routine in English, like 'when I get home, turn on the porch light and start the coffee maker.' This tool generates and previews that entire automation workflow so you know exactly what it’ll do before anything runs.

Once you're happy with a preview, you can manually run it by calling trigger_ai_zap with the specific Zap ID. If you need to expose new, custom actions for your agent to use down the line, run get_zapier_config_link to get the necessary configuration link and open up those capabilities.

It's straightforward: You list what’s available (list_smarthome_actions, list_lighting_actions, etc.), you search for what you need (search_zapier_actions), and then you execute the command using your natural language or a direct ID call. Your agent handles all the messy backend routing.
