A modern community platform for creators. Connects with an API key [circle.so](https://circle.so/) **15** triggers **21** actions What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it. ## What do you want to automate with Circle? Give your AI client this address. `https://mcp.apiant.ai` One connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser. ### Set it up in your client ### Claude Code Run this in the directory you want to work in. `claude mcp add --transport http -s project apiant-ai https://mcp.apiant.ai` Start Claude Code there, approve the server, and sign in in the browser page it opens.

APIANT's MCP server at https://mcp.apiant.ai works with Circle. Add that address to any AI client that takes a remote MCP server and sign in once in your browser. Your client can then run Circle actions on demand, or have APIANT build, test and run automations that use Circle. Nothing to install. ### ### What can start an automation from Circle? Any of Circle's 15 triggers in the catalog, including New Access Group, New Comment Posted, New Event Created and New Event RSVP. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Circle? Any of Circle's 21 actions, including Create Comment, Create Contact, Create Course Section and Mark Course Lesson as Completed. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can I use Circle directly from Claude, ChatGPT or Cursor? Yes. Connect your AI client to APIANT once and it works with Circle two ways. Ask it to do something in Circle once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running on its own. A one-off action uses your plan's tasks the same way an automation step does. ### ### Do I need to write code against the Circle API? No. APIANT connects to the Circle API for you, with your Circle API key. Describe what you want in plain language and your agent builds it on the Circle triggers and actions in the catalog. If you need an endpoint that is not there yet, your agent reads the Circle API documentation and adds it. ### ### Which apps can Circle connect to? Any app in the catalog; the list on this page pairs Circle with each of them. If the other app is missing, point your agent at its API documentation and it builds the connector. ### ### What happens when something fails? Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships. ### ### Is there a free plan? Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
