WHAT IT DOES

What manage_roles does on Ncp

AI agents use manage_roles to create or update resources in Ncp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ncp environment.

RISK

Why manage_roles is rated Medium

Managing roles is a write operation that modifies user permissions and access levels in a Discord server. While not destructive (roles can be reassigned), and not financial, this has significant blast radius if misused by an AI agent—it could grant excessive privileges, remove user access, or disrupt server administration.

From the tool's definition Tool name 'manage_roles' and description 'Manage user roles in Discord server' indicate the ability to create, modify, or assign user roles. This is a write operation that alters access control and permissions.

RECOMMENDED RULE

The rule that runs manage_roles safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ncp, 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.

}

The button opens the PolicyLayer dashboard: create your workspace, connect Ncp, apply this rule, and every manage_roles call is checked against it from then on.
