AI agents call list_roles to retrieve information from Plane without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to retrieve or list existing roles from the Plane system with no side effects. It follows the 'list' pattern characteristic of Read operations. The empty description slightly reduces confidence, but the naming pattern is sufficiently clear. This poses minimal risk as it only retrieves information without creating, modifying, or deleting data.
From the tool's definition Tool name 'list_roles' indicates a retrieval operation that queries and enumerates roles without modification. No description provided, but the name follows standard read-operation naming conventions.
Attacks that exploit this kind of access
list_roles. It is categorised as a Read tool in the Plane MCP Server, which means it retrieves data without modifying state.
Register the Plane 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 Plane. 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 Plane MCP server (@makeplane/plane-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
