+Access Control lets workspace admins define permission groups that restrict what each set of workspace members can do — which AI model providers they can use, which workflow blocks they can place, and which platform features are visible to them. Permission groups are scoped to a single workspace: a user can be in different groups (or no group) in different workspaces. Restrictions are enforced both in the workflow executor and in Mothership, based on the workflow's workspace.

 ## How it works
 
-Access control is built around **permission groups**. Each group has a name, an optional description, and a configuration that defines what its members can and cannot do. A user can belong to at most one permission group at a time.

Workspace permissions (Read, Write, Admin) control what a user can do within a specific workspace, such as viewing, editing, or managing workflows. A user needs both an organization role and a workspace permission to work within a shared workspace." },
   { question: "How many workspaces can I create?", answer: "Free users get 1 personal workspace. Pro users get up to 3 personal workspaces. Max users get up to 10 personal workspaces. Team and Enterprise plans support unlimited shared workspaces under the organization — new invites are gated by your seat count." },
   { question: "What happens to my shared workspaces if I cancel or downgrade my Team plan?", answer: "Existing shared workspaces remain accessible to current members, but new invitations are disabled until you upgrade back to a Team or Enterprise plan. No workspaces or members are deleted — the organization is simply dormant until billing is re-enabled." },

When a workflow runs, if both a personal and workspace variable share the same name, the personal value is used. This allows individual users to override shared workspace configuration when needed." },

A permission group can hide UI sections (like trace spans, knowledge base, API keys, or deployment options), disable features (MCP tools, custom tools, skills, invitations), and restrict which integrations and model providers members can access.
