Greenhouse **15** triggers Greenhouse **30** 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 Greenhouse 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.

Any of Greenhouse's 15 triggers in the catalog, including Application Updated, Candidate Updated, Job Updated and New Candidate. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Slack when something happens in Greenhouse? Any of Slack's 60 actions, including Create Canvas, Create Channel, Create Channel Canvas and Create Reminder. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Slack to Greenhouse? Yes. When something happens in Slack, your agent can act in Greenhouse too. This page covers both directions: Slack's triggers and Greenhouse's actions are listed here as well. ### ### Do I have to build a connector for Greenhouse 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 Greenhouse 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.
