What Particle (BYOK) is for

Particle (BYOK) lets an AI assistant read your own Particle data through the Particle API with a key you supply (access token of a product team member (scopes devices:list, devices:get, groups:list, devices.variable:get, devices.function:call)). Read-only: 4 tools (list_product_devices, get_product_device, read_product_variable, list_device_groups). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.particle.io. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Particle. Particle and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "Which devices in my Particle product are running old firmware?"
• "Which functions does device 0123456789abcdef01234567 of my Particle product expose?"
• "What is the temperature variable of device 0123456789abcdef01234567 in my Particle product?"
• "Which device groups does my Particle product have?"

What it does

• list_product_devices: List devices of a product fleet with optional filters and sorting. Needs a token with devices:list scope. Pages of 25 by default.
• get_product_device: Get one device of a product fleet: firmware, desired firmware, groups, quarantine state, last contact and the names of the functions and variables it exposes. Needs devices:get scope.
• read_product_variable: Read the current value of one cloud variable of a product device (for example a temperature or counter). The device must be online.
• list_device_groups: List the device groups of a product (name, description, firmware version, color), optionally filtered by part of the name.

BYOK key

You bring your own Particle access token of a product team member (scopes devices:list, devices:get, groups:list, devices.variable:get, devices.function:call) (https://docs.particle.io/reference/cloud-apis/access-tokens/). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.particle.io over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

• https://docs.particle.io/reference/cloud-apis/api/ (the API this connector calls, with a BYOK key)

Live from the Particle API (api.particle.io) with a BYOK key; documentation: https://docs.particle.io/reference/cloud-apis/api/. Endpoints checked against that documentation on 2026-10-16.

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Particle. Particle and its logos are trademarks of their owners and are used only to say which service the connector works with. It is read-only: it never creates, changes, sends or deletes anything in your Particle account.

Particle (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Particle (BYOK) is. Particle (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Particle data: Read the devices, device groups and cloud variables of your Particle product fleet and call a function on one product device, with your own access token. You bring your own Particle access token of a product team member (scopes devices:list, devices:get, groups:list, devices.variable:get, devices.function:call); the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Particle call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.particle.io, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Particle rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What Particle receives. The request we make on your behalf, including the key and the arguments, under Particle's own terms and privacy policy. Particle acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Particle gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your Particle data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. Particle (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at Particle at any time to end all access.

Children. Particle (BYOK) is a general-audience service operated by the adult using the assistant, under Particle's own age rules.

Changes. We will post changes here with a new effective date.
