What invite-user does on Descope MCP Server
AI agents use invite-user to create or update resources in Descope MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Descope MCP Server environment.
Why invite-user is rated Medium
This tool creates new user accounts and generates invitations, which are reversible write operations. While it modifies the system state by adding users, this can be undone (users can be deleted). It does not execute arbitrary code, delete data irreversibly, or move money.
From the tool's definition Tool description states 'Create and invite a new user to the Descope project' — this involves creating new user entities and sending invitations, both of which are data creation and modification operations.
Attacks that exploit this kind of access
The rule that runs invite-user safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Descope MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For invite-user, this is the rule to start with:
invite-user stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Descope MCP Server, apply this rule, and every invite-user call is checked against it from then on.
