## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "remember",
    "arguments": {}
  }
}
```

## Why remember is rated Medium

The tool writes data (a memory entry) to persistent storage for the agent. It is reversible in principle (memories could be overwritten or deleted), affects only the agent's own state within a sandboxed world engine, and has minimal blast radius. No code execution, deletion, or financial action is involved.

From the tool's own definition: "'Store a memory of your own' — creates/persists a new memory record for the agent"

## Use case

AI agents use remember to create or update resources in A2A-MCP-World, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your A2A-MCP-World environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches A2A-MCP-World:

```json

  "tools": {
    "remember": {
      "limits": [
        {
          "counter": "remember_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
