列出知識庫中所有客戶名稱，用於過濾特定客戶的知識
AI agents call list_customers to retrieve information from EKMS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists customer names from the knowledge base for filtering purposes. It has no side effects—it only queries and returns data without creating, modifying, deleting, or executing external operations. This is a classic Read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'list_customers' and description '列出知識庫中所有客戶名稱，用於過濾特定客戶的知識' (list all customer names in the knowledge base for filtering knowledge by specific customer) indicates data retrieval with no modification or deletion.

Register the EKMS MCP Server MCP server in PolicyLayer and add a rule for list_customers: 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 EKMS MCP Server. Nothing to install.
list_customers 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_customers 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_customers. 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_customers is provided by the EKMS MCP Server MCP server (jihsin/ekms-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
