AI agents call zentao_users to retrieve information from Zentao MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only performs data retrieval operations on user information. It retrieves user lists, user details, and information about the current user. There are no side effects, no data modifications, no code execution, and no destructive actions. This is a pure Read category tool with minimal risk—typical for user directory/profile lookups in project management systems.
From the tool's definition Tool name 'zentao_users' with description indicating support for: 'query list, query details, query current user' (translated from Chinese: 查询列表、查询详情、查询当前用户). All operations are read-only queries with no modification, deletion, or execution capabilities.
Documented attack patterns abuse exactly the kind of access zentao_users gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Zentao MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for zentao_users:
{
"version": "1",
"default": "deny",
"tools": {
"zentao_users": {}
}
}zentao_users is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

用户操作。支持：查询列表、查询详情、查询当前用户. It is categorised as a Read tool in the Zentao MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Zentao MCP Server MCP server in PolicyLayer and add a rule for zentao_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 Zentao MCP Server. Nothing to install.
zentao_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 zentao_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 zentao_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.
zentao_users is provided by the Zentao MCP Server MCP server (tytt/zentao-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Zentao MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
