Can my AI read sensor data from my Particle devices?

Yes! Use the `read_variable` tool with your device ID and the variable name (e.g., temperature, humidity, soilMoisture). Your device must expose this variable in its firmware using `Particle.variable()`. The AI will return the current sensor value in real-time. You can find available variables using `get_device_info`.

How do I remotely turn on a pump or actuator connected to a Particle device?

Use the `call_function` tool with your device ID and the function name (e.g., pumpOn, valveOpen). The function must be exposed in your device firmware using `Particle.function()`. You can pass an optional argument (like duration or intensity) to control the actuator behavior. Check available functions with `get_device_info`.

Can I check if my IoT device is online and responding?

Yes! Use the `ping_device` tool to instantly check the online status of any Particle device. You can also use `get_devices` to see the online status of all your devices at once. If a device shows as offline, it may be powered off, disconnected from Wi-Fi, or experiencing firmware issues.

Particle IoT MCP Tools for LangChain (8)

These 8 tools become available when you connect Particle IoT to LangChain via MCP:

call_function

Functions are defined in the device firmware and can control actuators (turn on pump, open valve), trigger calibrations, change device modes, or perform system tasks. Accepts a single string argument (max 63 characters) to pass to the function. Returns the function execution result code. Essential for remote device control, automation, and actuator management. AI agents should use this when users ask "turn on the water pump on device X", "trigger calibration on sensor Y", or need to remotely control any function exposed by a device. Execute a cloud function on a specific Particle IoT device

get_device_info

Essential for understanding device capabilities before interacting with it. AI agents should reference this when users ask "what variables does device X expose", "what functions can I call on device Y", or need to understand the specific interface of a device. Get detailed information about a specific Particle IoT device

get_devices

Returns device IDs, names, online status, firmware versions, and last connection times. Essential for device inventory management, monitoring connection health, and selecting specific devices for interaction. AI agents should use this when users ask "show me all my devices", "list connected sensors", or need to identify available devices before reading variables or calling functions. List all Particle IoT devices connected to your account

ping_device

Returns current online/offline status and last heard time. Essential for connectivity diagnostics, health monitoring, and verifying device availability before attempting to read variables or call functions. AI agents should reference this when users ask "is device X online", "check connectivity for sensor Y", or need to troubleshoot device communication issues. Check if a specific Particle IoT device is online and responsive

publish_event

Events are broadcast to all subscribed listeners and can be used for inter-device communication, logging, alerting, or triggering external workflows via webhooks. Requires an event name and optional data string (max 255 bytes for data). Essential for sending alerts, logging custom data, and integrating with external systems like IFTTT or custom dashboards. AI agents should use this when users ask "send a low moisture alert", "publish a system status event", or need to broadcast data from the cloud to devices or webhooks. Publish a custom event to the Particle Cloud

read_variable

Variables are defined in the device firmware and can represent sensor readings (temperature, humidity, soil moisture), system status, or configuration values. Returns the variable name, data type, and current value. Essential for real-time sensor monitoring, data collection, and system state verification. AI agents should use this when users ask "what is the temperature from sensor X", "read soil moisture from device Y", or need to get the current value of any sensor or status variable. Read the current value of a cloud variable from a specific device

rename_device

This name appears in the console and API responses, making it easier to identify devices. Essential for device organization, fleet management, and improving readability of device lists. AI agents should use this when users ask "rename device X to Greenhouse Sensor 1", "change the name of device Y to Pump Controller", or need to update device naming for better organization. Rename a specific Particle IoT device

unclaim_device

This action is irreversible for the current account and should be used when transferring device ownership or decommissioning devices. Essential for device lifecycle management, transferring devices, and account cleanup. AI agents should use this when users ask "remove device X from my account", "unclaim sensor Y so I can sell it", or need to manage device ownership. WARNING: This requires confirmation as it removes access to the device. Remove a Particle IoT device from your account

Example Prompts for Particle IoT in LangChain

Ready-to-use prompts you can give your LangChain agent to start working with Particle IoT immediately.

"Show me all my connected Particle devices and their online status."
