AI agents call list_tenants to retrieve information from WeKnora 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 read-only operation to list tenants. It retrieves data with no side effects, no code execution, no data modification, and no destructive operations. The low severity reflects minimal risk even if misused by an agent—listing tenants is informational only and does not compromise system integrity or enable further unauthorized actions on its own.
From the tool's definition Tool name 'list_tenants' and description 'List all tenants' indicate a query operation that retrieves/enumerates existing tenant data without modification.
Documented attack patterns abuse exactly the kind of access list_tenants gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and WeKnora MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_tenants:
{
"version": "1",
"default": "deny",
"tools": {
"list_tenants": {}
}
}list_tenants is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all tenants. It is categorised as a Read tool in the WeKnora MCP Server MCP Server, which means it retrieves data without modifying state.
Register the WeKnora MCP Server MCP server in PolicyLayer and add a rule for list_tenants: 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 WeKnora MCP Server. Nothing to install.
list_tenants 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_tenants 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_tenants. 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_tenants is provided by the WeKnora MCP Server MCP server (nannaolympicbroadcast/weknoramcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from WeKnora 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.
