What Circle (BYOK) is for

Circle (BYOK) lets an AI assistant read your own Circle data through the Circle API with a key you supply (Circle Admin API v2 token (Business plan or above)). Read-only: 11 tools (get_community, list_spaces, list_space_groups, list_posts, list_comments, list_events, list_topics, list_member_tags, list_access_groups, list_forms, list_flagged_contents). 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 app.circle.so. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Circle. Circle 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 Circle community is my token connected to?"
• "What spaces does our Circle community have?"
• "How are our Circle spaces grouped?"
• "What are the latest posts in our Circle community?"
• "How many comments are on Circle post 1001?"
• "What events are coming up in our Circle community?"

What it does

• get_community: Show the community the token belongs to: name, slug, locale, privacy, creation date and digest setting.
• list_spaces: List the community's spaces with type, privacy, draft and hidden flags and URL.
• list_space_groups: List the space groups (sidebar sections) with counts of spaces and members.
• list_posts: List basic posts with title, status, space, author name, comment and like counts and dates.
• list_comments: List comments with reply and like counts, date and URL; filter by space or post. Comment text is not returned.
• list_events: List events with start and end time, location type and like and comment counts.
• list_topics: List the topics used to organize posts.
• list_member_tags: List member tags with color, visibility and how many members carry each.
• list_access_groups: List access groups (paid or gated member groups) with status and description.
• list_forms: List forms with status and number of submissions.
• list_flagged_contents: List content reported by members for moderation with reason, status and dates. Names and emails are left out.

BYOK key

You bring your own Circle Circle Admin API v2 token (Business plan or above) (https://api.circle.so/apis/admin-api/quick-start). 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 app.circle.so 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://api.circle.so/apis/admin-api (the API this connector calls, with a BYOK key)

Live from the Circle API (app.circle.so) with a BYOK key; documentation: https://api.circle.so/apis/admin-api. Endpoints checked against that documentation on 2026-10-16.

What it is not

Circle 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 Circle account.

Circle (BYOK) — Privacy Policy

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

What Circle (BYOK) is. Circle (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Circle data: Read your Circle community: spaces, posts, comments, events, topics, member tags, access groups, forms and flagged content with your own Admin API token. You bring your own Circle Circle Admin API v2 token (Business plan or above); the assistant sends it to us with each request.

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

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

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

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