# list_memories

List all memories with optional filtering. Best practice: set an active project first to avoid mixing contexts from different workspaces. Use default (full_text=false) for quick browsing; set full_text=true only when you need complete content. For many items, consider using search_memory with relevant keywords instead.

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

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

## Why list_memories is rated Low

This tool retrieves and queries memory data without any side effects. The description emphasizes it is for 'quick browsing' and explicitly recommends alternatives for searching, confirming it performs read-only operations. The optional 'full_text' parameter controls output verbosity but does not modify underlying data. No data creation, modification, deletion, or execution occurs.

From the tool's own definition: "Tool name is 'list_memories' and description states it 'List all memories with optional filtering' and recommends using 'search_memory' for querying content, indicating this is a retrieval operation with no modification capability."

## Use case

AI agents call list_memories to retrieve information from Cognio without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Cognio:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_memories": {}
  }
}
```
