List admin-visible users.
AI agents call list_admin_users to retrieve information from Mealie MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns user information visible to admins. It performs a retrieval operation with no capability to modify, delete, or execute actions. While the data returned (user information) is sensitive, the tool itself only reads existing data. Severity is low because listing users, while potentially sensitive, is a standard read operation with no destructive, financial, or execution impact.
From the tool's definition Tool name is 'list_admin_users' and description states 'List admin-visible users' — the verb 'List' indicates a read operation that retrieves data without modification or side effects.

List admin-visible users. It is categorised as a Read tool in the Mealie MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Mealie MCP Server MCP server in PolicyLayer and add a rule for list_admin_users: 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 Mealie MCP Server. Nothing to install.
list_admin_users 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_admin_users 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_admin_users. 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_admin_users is provided by the Mealie MCP Server MCP server (nikopol666/mealie-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
