How to control memory_batch ↓

AI agents use memory_batch to create or update resources in MCP AI Memory — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP AI Memory environment.

Medium Risk

This tool creates or modifies data (memories) in a reversible manner. While 'batch_delete' exists as a separate tool on the server, this tool is explicitly described as storing/importing data, not deleting it.

From the tool's definition Tool description explicitly states 'Store multiple memories at once' and includes keywords 'batch, bulk, multiple, import, mass store, save many, store all, bulk import, batch save'. This is a create/modify operation that writes data to the memory system.

Documented attack patterns abuse exactly the kind of access memory_batch gives an agent:

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "memory_batch": {
      "limits": [
        {
          "counter": "memory_batch_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

memory_batch stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register MCP AI Memory — 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.

What does the memory_batch tool do? +

BATCH BULK MULTIPLE IMPORT - Store multiple memories at once for efficiency. Keywords: batch, bulk, multiple, import, mass store, save many, store all, bulk import, batch save. It is categorised as a Write tool in the MCP AI Memory MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on memory_batch? +

Register the MCP AI Memory MCP server in PolicyLayer and add a rule for memory_batch: 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 MCP AI Memory. Nothing to install.

What risk level is memory_batch? +

memory_batch is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit memory_batch? +

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

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

memory_batch is provided by the MCP AI Memory MCP server (scanadi/mcp-ai-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every MCP AI Memory tool call.
