AI agents call list_kb_members to retrieve information from Yunxiao without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
kbId | string | Yes | Knowledge base ID. Use list_knowledge_bases to discover valid IDs. |
page | number | — | Page number for pagination. Starts at 1. |

Parameters from the server's own tool schema.
This tool retrieves and enumerates access control information (knowledge base members). It performs a read-only query with no capability to modify, delete, or execute operations. The blast radius of misuse is limited to information disclosure about who has access to a knowledge base, which is relatively low risk in a DevOps context.
From the tool's definition Tool name 'list_kb_members' and description 'List members with access to a Tongyi Lingma knowledge base' indicate a retrieval operation that queries membership data without modification or side effects.
Attacks that exploit this kind of access
List members with access to a Tongyi Lingma knowledge base. Use list_knowledge_bases to discover valid kbId values. It is categorised as a Read tool in the Yunxiao MCP Server, which means it retrieves data without modifying state.
list_kb_members accepts 7 parameters: kbId, page, sort, query, orderBy, perPage, organizationId. Required: kbId. The full parameter table on this page comes from the server's own tool schema.
Register the Yunxiao MCP server in PolicyLayer and add a rule for list_kb_members: 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 Yunxiao. Nothing to install.
list_kb_members 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_kb_members 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_kb_members. 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_kb_members is provided by the Yunxiao MCP server (@futuretea/yunxiao-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
