WHAT IT DOES

What manage_roles does on Supabase MCP Server - Self-Hosted Edition

AI agents use manage_roles to create or update resources in Supabase MCP Server - Self-Hosted Edition, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Supabase MCP Server - Self-Hosted Edition environment.

RISK

Why manage_roles is rated Medium

Role management typically involves creating, updating, or modifying user roles and permissions in a database system. This is a Write operation as it creates or modifies access control data reversibly. However, confidence is moderate (0.72) because the tool description is empty, leaving some ambiguity about exact scope.

From the tool's definition Tool name 'manage_roles' combined with server context describing 'comprehensive management of self-hosted or cloud Supabase instances' and 'authentication' capabilities indicates role creation/modification operations.

RECOMMENDED RULE

The rule that runs manage_roles safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Supabase MCP Server - Self-Hosted Edition, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For manage_roles, this is the rule to start with:

manage_roles Rate-limited

manage_roles 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.
