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). Read-only: 11 tools (get_community, list_spaces, get_space, list_posts, get_post, list_comments, list_events, get_event, list_space_groups, list_topics, list_member_tags). 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:

• "What is the name and privacy of my Circle community?"
• "Which spaces does my Circle community have?"
• "Show details of this Circle space"
• "What are the latest published posts in this Circle space?"
• "Show this Circle post"
• "What comments were posted on this Circle post?"

What it does

• get_community: Show the Circle community the token belongs to: name, slug, locale, privacy and default space settings.
• list_spaces: List the spaces of a Circle community with type, privacy, draft flag and group. Admin API plan quotas apply.
• get_space: Get one Circle space by ID with type, privacy, URL and space group.
• list_posts: List posts of a Circle community, optionally for one space or group, by status or search text; returns metadata and counts.
• get_post: Get one Circle post by ID with title, author name, space, comment count, dates and plain body text.
• list_comments: List comments in a Circle community, optionally for one space or post, with author name, reply and like counts.
• list_events: List events of a Circle community with start and end time, location type and comment count, optionally within a date range or space.
• get_event: Get one Circle event by ID with times, location type, location and comment count.
• list_space_groups: List the space groups of a Circle community, optionally filtered by name.
• list_topics: List the topics of a Circle community, optionally filtered by name and sorted.
• list_member_tags: List the member tags of a Circle community with names and public flag.

BYOK key

You bring your own Circle Circle Admin API V2 token (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

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 and member tags with your own Admin API V2 token. You bring your own Circle Circle Admin API V2 token; 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.
