Describe the whole flow and it is built, tested on every scenario and kept running. OpenAI **5** triggers OpenAI **69** actions Slack **15** triggers Slack **60** actions What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it. ## What do you want OpenAI and Slack to do together? 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. [Claude Code guide (opens in a new tab)](https://apiant.ai/docs/mcp/claude-code) ### Claude, web and desktop Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Cursor Add the address to your MCP configuration as a server URL. Cursor signs you in in your browser. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Zed Open Settings, then AI, then MCP Servers, then Add Server, then Add Remote Server. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Codex and the ChatGPT desktop app Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Any other MCP client Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) Connecting Slack and OpenAI lets messages, files and mentions from your workspace go straight to a model, and brings model output back into the channels people already watch. A question posted in Slack can be checked for harmful content, answered with a drafted reply, or turned into text from an uploaded recording. Work in OpenAI can be announced back in Slack.

Yes. A message posted to a chosen channel can trigger a call to OpenAI, and the model's reply can be posted with Send Message or sent to one person with Send Direct Message. You can also add a reaction to the original message to mark it handled. ### ### What happens if a Slack message contains something we do not want sent onward? You can run the message through the OpenAI content moderation action first, which classifies text for categories such as hate, harassment and violence. The rest of the scenario only continues when the result comes back clean, and the agent tests every scenario before it goes live. ### ### What can start an automation from OpenAI? Any of OpenAI's 5 triggers in the catalog, including New model, New video, New batch and New file. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Slack when something happens in OpenAI? Any of Slack's 60 actions, including Send Direct Message, Send Message, Create Canvas and Create Channel. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Slack to OpenAI? Yes. When something happens in Slack, your agent can act in OpenAI too. This page covers both directions: Slack's triggers and OpenAI's actions are listed here as well. ### ### Do I have to build a connector for OpenAI or Slack? No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running. ### ### Can my AI client use OpenAI and Slack without building an automation? Yes. With your AI client connected to APIANT, ask it to do something in either app 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. One connection covers both. ### ### 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.
