List all roles of a specific client in a specific realm
AI agents call list-roles to retrieve information from Advanced Keycloak MCP server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a data retrieval operation querying existing roles within a Keycloak client and realm. It has no side effects, does not modify data, does not delete resources, and does not execute code or trigger external operations. The blast radius of misuse is minimal—an agent could enumerate roles but cannot alter configurations, create unauthorized roles, or escalate privileges through this tool alone.
From the tool's definition Tool name 'list-roles' and description 'List all roles of a specific client in a specific realm' indicate a read-only operation that retrieves role information without modifying, deleting, or executing any operations.
Attacks that exploit this kind of access
List all roles of a specific client in a specific realm. It is categorised as a Read tool in the Advanced Keycloak MCP server MCP Server, which means it retrieves data without modifying state.
Register the Advanced Keycloak MCP server MCP server in PolicyLayer and add a rule for list-roles: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Advanced Keycloak MCP server. Nothing to install.
list-roles is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list-roles rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list-roles. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list-roles is provided by the Advanced Keycloak MCP server MCP server (octodet/keycloak-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
