AI agents call mem_history to retrieve information from MemoV without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries historical data without side effects. It allows viewing past AI interactions and code changes but does not modify, execute, delete, or create new data. The blast radius of misuse is minimal—an agent could only access memory history it should already have access to, which is a Read-category operation.
From the tool's definition Tool name 'mem_history' and description explicitly states 'View memov history' and 'Browse the history'. The purpose is to retrieve and display historical records of snapshots, prompts, responses, and file changes.
Documented attack patterns abuse exactly the kind of access mem_history gives an agent:
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_history:
{
"version": "1",
"default": "deny",
"tools": {
"mem_history": {}
}
}mem_history is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

View memov history - list of snapshots with prompts, responses, and file changes. Purpose: Browse the history of AI-assisted code changes recorded by memov. Each entry shows what was asked, what was done, and which files were changed. When to use: - To understand what changes were made previously - To review the sequence of AI interactions Args: limit: Maximum number of commits to return (default: 20, max: 50) commit_hash: If provided, show detailed info for this specific commit only Returns: Formatted history with commit info, prompts, responses, and files. It is categorised as a Read tool in the MemoV MCP Server, which means it retrieves data without modifying state.
Register the MemoV MCP server in PolicyLayer and add a rule for mem_history: 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.
mem_history 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 mem_history 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 mem_history. 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.
mem_history 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.
Start from MemoV, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
