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

```json
{
  "jsonrpc": "2.0",

  "params": {
    "name": "episodic_search",
    "arguments": {}
  }

## Why episodic_search is rated Low

This tool retrieves historical episodic memory data based on search criteria. It has no capability to modify, delete, execute code, or perform financial operations. The blast radius of misuse is minimal—an agent could retrieve irrelevant or sensitive historical context, but cannot alter system state or trigger external actions. This is a straightforward read/query operation.

From the tool's own definition: "Tool performs 'Return past episodic events matching a keyword query' - a retrieval operation with no modification or execution capability. The verb 'Return' and the query-based nature indicate data retrieval only."

## Use case

AI agents call episodic_search to retrieve information from CogniRepo 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 CogniRepo:

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