What Zeplin (BYOK) is for

Zeplin (BYOK) lets an AI assistant read your own Zeplin data through the Zeplin API with a key you supply (Zeplin personal access token). Read-only: 11 tools (get_current_user, list_projects, get_project, list_organizations, list_organization_projects, list_screens, get_screen, list_screen_notes, list_colors, list_text_styles, list_components). 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.zeplin.dev. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Zeplin. Zeplin 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 Zeplin account is my token connected to?"
• "Which Zeplin projects do I have?"
• "How many screens does this Zeplin project have?"
• "Which Zeplin organizations am I in?"
• "What projects does my Zeplin organization have?"
• "What screens are in this Zeplin project?"

What it does

• get_current_user: Show the Zeplin user the token belongs to: id, username and last seen time.
• list_projects: List the Zeplin projects the user is a member of, with platform, status and counts of screens, components, colors and text styles.
• get_project: Get one Zeplin project with description, platform, status, counts of its contents and a link to view it.
• list_organizations: List the Zeplin organizations the user belongs to, optionally filtered by role.
• list_organization_projects: List all projects of one Zeplin organization with status, workflow status and content counts.
• list_screens: List the screens of a Zeplin project with tags, notes count, versions count and image metadata (URLs only).
• get_screen: Get one Zeplin screen with its description, tags, note and version counts and image metadata (URLs only).
• list_screen_notes: List the review notes pinned on a Zeplin screen with status, order, creator and creation time.
• list_colors: List the color tokens of a Zeplin project as RGBA values with names.
• list_text_styles: List the text styles of a Zeplin project: font family, size, weight, line height and alignment.
• list_components: List the components of a Zeplin project with description, section and preview image metadata (URLs only).

BYOK key

You bring your own Zeplin Zeplin personal access token (https://app.zeplin.io/profile/developer). 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.zeplin.dev 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.zeplin.dev/reference/getprojects (the API this connector calls, with a BYOK key)

Live from the Zeplin API (api.zeplin.dev) with a BYOK key; documentation: https://docs.zeplin.dev/reference/getprojects. 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 Zeplin. Zeplin 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 Zeplin account.

Zeplin (BYOK) — Privacy Policy

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

What Zeplin (BYOK) is. Zeplin (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Zeplin data: Read your Zeplin design handoff projects, screens, notes, colors, text styles and components with your own personal access token. You bring your own Zeplin Zeplin personal access token; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Zeplin 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.zeplin.dev, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Zeplin 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 Zeplin receives. The request we make on your behalf, including the key and the arguments, under Zeplin's own terms and privacy policy. Zeplin acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Zeplin 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 Zeplin 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. Zeplin (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 Zeplin at any time to end all access.

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

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