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

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

## Why store_memory is rated Medium

The name 'store_memory' strongly suggests a write operation — persisting data (likely memory/context) to storage. This aligns with the server's stated purpose of 'persistent memory and context for AI tools.' Since the description is empty, confidence is reduced, but the name and server context together suggest a reversible write (store/create) rather than anything more severe.

From the tool's own definition: "Tool name 'store_memory' implies creating or saving data to persistent memory storage."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "store_memory": {
      "limits": [
        {
          "counter": "store_memory_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
