Announcing Proliferate
Proliferate

Cursor

Bring your Cursor account into Proliferate workspaces, with Cursor's own agent, plan, and ask modes.

Cursor runs through the Cursor Agent CLI, so your team brings the Cursor account, models, and modes it already uses into shared workspaces and review.

Supported functionality

CapabilitySupport
Where it runsLocal checkouts and worktrees.
ModesCursor's own agent, plan, and ask modes, switched from the composer.
SubagentsSpawn native task agents, or delegate to a separate session.
CredentialsSigns in with the Cursor CLI's own login; no separate Proliferate credential.

Modes

Cursor carries its own mode switch into the composer, separate from the session modes other agents use.

ModeWhat it does
AgentDefault. Makes changes directly: edits files and runs commands as it works.
PlanCursor's own plan mode: it works out an approach before making changes, using Cursor's native planning behavior.
AskRead-only. Answers questions and explores the codebase without editing anything.

Subagents

Cursor can spawn its own task agents (cursor/task) inside a session — native subagents that show up in the session's activity roster. To hand a scoped piece of work to a separate Proliferate session instead, see Parallel agents.

Authentication

Cursor signs in with the Cursor CLI's own login (cursor-agent login); if cursor-agent is already logged in on your machine, Proliferate picks that up automatically. From Settings -> Agents -> Cursor you can also select API key and save a Cursor account key instead. Cursor doesn't support the Proliferate Gateway.

For how routes work on the agents that do support them, see Authentication.

Info:

Cursor doesn't appear in an organization's Allowed harnesses checklist, since there's no route to restrict. See Agent policy for what that checklist does control.
