Why create_memory_cluster needs a policy

This is a Write-category tool: it creates a new data structure (memory cluster) that is reversible through deletion or archival. The operation has side effects (adds to the memory system) but does not irreversibly destroy data, execute arbitrary code, or involve financial transactions.

From the tool's definition Tool description states 'Create a new memory cluster', indicating a create operation that modifies system state by adding a new cluster entity to the memory system.

POLICY

How to control create_memory_cluster

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

policy.json

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

create_memory_cluster 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 AGI 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 create_memory_cluster

What does the create_memory_cluster tool do? +

Create a new memory cluster. It is categorised as a Write tool in the AGI 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 create_memory_cluster? +

Register the AGI MCP Server MCP server in PolicyLayer and add a rule for create_memory_cluster: 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 AGI MCP Server. Nothing to install.

What risk level is create_memory_cluster? +

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

Can I rate-limit create_memory_cluster? +

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

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

create_memory_cluster is provided by the AGI MCP Server MCP server (quixiai/agi-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every AGI MCP Server tool call.

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