How do I connect Discourse?

Add the Discourse piece to a flow, then authenticate with Custom auth. Once connected, its 5 triggers and 6 actions are available anywhere in the builder.

What can I automate with Discourse?

"New Post" can start a flow that runs "Create Post", and you can chain Discourse together with any of 770+ other apps and AI steps in between.

Can I self-host the Discourse integration?

Yes. Activepieces is fully self-hostable, so you can run the Discourse piece on your own infrastructure with your connections and your data staying in your environment.

Can my AI agent use Discourse as a tool?

Yes. Every piece you connect can be exposed over one Activepieces MCP server, so Claude, Cursor, Windsurf or any MCP client can call Discourse actions as tools.
