Hey there!

We’re quite close on this one, but it’s not GA yet. Sorry for the mix-up.

Can you chime in here when it is released to GA?

Same issue here. We need Cloud Agents from Slack to create documents in Outline via MCP.

Is there a way to configure MCP for Cloud Agents at team level? Or any workaround? Our use case: sales team creates offers via @Cursor in Slack — we need direct publication to Outline, not just local file.

Same, I’m a bit shocked that cloud agents have been around this long and don’t have MCP. Codegen (already acquired), EngineLabs, what not already supported it

Please let us know when this is live! I’m sure you have hundreds of user looking to control their codebase via Slack and without DB/MCP access cloud agents are largely futile cause they lack data context

Does the Feb 24, 2026 release now enable Cloud Agents to use custom MCP servers? Please explain where in the Cursor Cloud Agent API an MCP configuration can be supplied in the launch payload. I don’t see a way to configure a custom MCP server for Cloud Agents via the Cursor Dashboard.

Per Cloud Agents API | Cursor Docs , it says “MCP (Model Context Protocol) is not yet supported by the Cloud Agents API.” When will it be supported because Capabilities | Cursor Docs implies that custom MCP servers are now supported.

Hey there @banool @svinuh @bholagabbar @Justin_Wickett

  1. You can find MCP Servers for Cloud Agents now on http://cursor.com/agents :slight_smile: A bigger launch is coming this week, but we’d love for you to try it out already!

  2. Cloud Agents created via the API should still be able to call MCPs, as long as you’ve enabled the MCPs for that repo via the Agents dashboard.

Gonna unlist this thread until our bigger announcement so I don’t steal it’s thunder, but wanted to update you guys since you’ve been so patient!
