What users-create does on Frontmcp
AI agents use users-create to create or update resources in Frontmcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Frontmcp environment.
Why users-create is rated Medium
This tool creates a new user record in a CRM system. It modifies data but the action is reversible through standard CRM operations (user deletion, deactivation). It does not execute arbitrary code, delete data irreversibly, move money, or perform financial transactions.
From the tool's definition Tool name 'users-create' and description 'Create a new user in the CRM' indicate data creation/modification that is reversible (users can typically be deleted or archived in CRM systems).
Attacks that exploit this kind of access
The rule that runs users-create safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Frontmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For users-create, this is the rule to start with:
users-create 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 Frontmcp, apply this rule, and every users-create call is checked against it from then on.
