WHAT IT DOES

What list_memory does on Hermoso

AI agents call list_memory to retrieve information from Hermoso without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_memory is rated Low

This is a straightforward data retrieval operation that queries stored configuration and preferences. It has no capability to modify, execute, delete, or create financial obligations. The read-only designation and free nature confirm it poses minimal risk if exposed to an AI agent.

From the tool's definition Tool description explicitly states 'List' and 'Read-only, free' — retrieves saved workspace data (brand facts, preferences, rules) without modification or side effects.

RECOMMENDED RULE

The rule that runs list_memory safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Hermoso, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_memory, this is the rule to start with:

list_memory Allowed

list_memory is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_memory": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Hermoso, apply this rule, and every list_memory call is checked against it from then on.

FAQ

Questions about list_memory

What does the list_memory tool do? +

List the durable facts & preferences saved in this workspace’s Memory (what the studio remembers about the brand, audience, taste, and do/don’t rules) — the same Memory the web app shows. These shape every future ad. Read-only, free. It is categorised as a Read tool in the Hermoso MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list_memory? +

Register the Hermoso MCP server in PolicyLayer and add a rule for list_memory: 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 Hermoso. Nothing to install.

What risk level is list_memory? +

list_memory is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list_memory? +

Yes. Add a rate_limit block to the list_memory 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.

How do I block list_memory completely? +

Set action: deny in the PolicyLayer policy for list_memory. 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.

What MCP server provides list_memory? +

list_memory is provided by the Hermoso MCP server (https://app.hermoso.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
