What mem_ui does on MemoV

AI agents invoke mem_ui to trigger actions in MemoV. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

High Risk

Why mem_ui needs a policy

This tool launches a local web server process, which constitutes executing an external operation (starting a server on a specified port). It's not merely reading data — it triggers a running process on the host system. Misuse could expose internal history on an unintended port or bind to network interfaces unexpectedly.

How to control mem_ui

PolicyLayer is an MCP gateway — it sits between your AI agents and MemoV, and nothing reaches the server without passing your rules. This is the rule we recommend for mem_ui:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "mem_ui": {
      "limits": [
        {
          "counter": "mem_ui_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

mem_ui stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register MemoV — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about mem_ui

What does the mem_ui tool do? +

Open the MemoV Web UI to visually browse your AI coding history. Purpose: Launch a local web interface for exploring your memov history with: - Timeline view of all commits - Branch filtering and navigation - Visual diff viewer for each file When to use: - To get a visual overview of your AI coding history - When you need to explore commits interactively - To compare changes across multiple snapshots Args: port: Port number for the web server (default: auto-select starting from 38888) Returns: URL to open in browser. It is categorised as a Execute tool in the MemoV MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on mem_ui? +

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

What risk level is mem_ui? +

mem_ui is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit mem_ui? +

Yes. Add a rate_limit block to the mem_ui 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 mem_ui completely? +

Set action: deny in the PolicyLayer policy for mem_ui. 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 mem_ui? +

mem_ui is provided by the MemoV MCP server (memovai/memov). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every MemoV tool call.

Start from MemoV, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
