Why mem0_add_procedural_memory needs a policy

The 'add' operation modifies the Mem0 persistent memory system by storing procedural memory, which is a reversible write action. While the description is uninformative, the naming pattern and server context (memory management) strongly suggest this creates or updates memory records.

From the tool's definition Tool name 'mem0_add_procedural_memory' contains 'add', indicating a create/modify operation. Sibling tools include 'mem0_add_*' (write operations) and 'mem0_delete_memory' (destructive), confirming this server manages persistent memory state.

POLICY

How to control mem0_add_procedural_memory

PolicyLayer is an MCP gateway — it sits between your AI agents and Mem0 MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for mem0_add_procedural_memory:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "mem0_add_procedural_memory": {
      "limits": [
        {
          "counter": "mem0_add_procedural_memory_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

mem0_add_procedural_memory 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.

Create a free account and register Mem0 MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about mem0_add_procedural_memory

What does the mem0_add_procedural_memory tool do? +

mem0_add_procedural_memory. It is categorised as a Write tool in the Mem0 MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on mem0_add_procedural_memory? +

Register the Mem0 MCP Server MCP server in PolicyLayer and add a rule for mem0_add_procedural_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 Mem0 MCP Server. Nothing to install.

What risk level is mem0_add_procedural_memory? +

mem0_add_procedural_memory is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit mem0_add_procedural_memory? +

Yes. Add a rate_limit block to the mem0_add_procedural_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 mem0_add_procedural_memory completely? +

Set action: deny in the PolicyLayer policy for mem0_add_procedural_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 mem0_add_procedural_memory? +

mem0_add_procedural_memory is provided by the Mem0 MCP Server MCP server (ryaker/mcp-mem0-general). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Mem0 MCP Server tool call.

Start from Mem0 MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
