Return all customers with their metadata.
AI agents call list_customers to retrieve information from Mock Store 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 customer data without any side effects. It is a straightforward read operation that retrieves existing information from the mock store's database. The 'list' verb and absence of any write, delete, or execute keywords confirm this is a Read category tool.

Register the Mock Store 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 Mock Store 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 Mock Store MCP Server MCP server (parishwolfe/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
