Where does the bug appear (feature/product)? Background Agent (GitHub, Slack, Web, Linear) Describe the Bug Cloud agents cannot use MCPs, even though I was told by support that this feature is now available: gist:de77afcf288b128a62b56be12698e40b · GitHub . Steps to Reproduce Start a cloud agent in …

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 Age…

Hey there @banool @svinuh @bholagabbar @Justin_Wickett 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! Cloud Agents created via the API should still be able to call MCPs, …

Colin, will Custom MCP servers be configurable programmatically on an Cloud Agent-by-Cloud Agent basis? Meaning is there an API endpoint to launch a Cloud Agent with a custom MCP server attached to it rather than manually having to manually define Custom MCP Server details at the Dashboard level?

MCP (Model Context Protocol) is not yet supported by the Cloud Agents API.

Thanks! I was able to configure Linear and Supabase. A bit confused as to how these work per repo. Am I able to configure MCPs per repository ? When I initiate a cloud agent from slack for example, do I tell it to use certain MCPs or will they always have access ?

Cloud agents, including those triggered by a Slack command, will automatically pick up MCP servers defined in .cursor/mcp.json in your repo. Read below! [image] Cloud Agents + MCP Bug Reports Thanks, everyone. It looks like some bad information got into our H…

@Colin This behaviour is not working for me. Cloud Agents do not pick up my .cursor/mcp.json file and start up the MCP processes in the background. Here is a thread demonstrating the behaviour: https://cursor.com/agents/bc-75e5954a-1210-4e3e-923c-7180402b3f28 Here is the mcp.json file { "mcpS…

Thanks, everyone. It looks like some bad information got into our Help Center (I’m opening a PR to fix this now). The supported way to add MCP Servers for Cloud Agents is to configure them via the dashboard: https://cursor.com/agents For users on a Team Plan: https://cursor.com/dashboard/integrat…

Thanks for the update. Configuring via the dashboard works. Can you please consider establishing a single source of truth for MCP config across local and agents? Having duplicated definitions across two mcp.json files means they may well drift apart over time, and it adds friction to the “it just w…
