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

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

## Why create_observation is rated Medium

The tool creates new observation records in what appears to be a knowledge management system. This is a Write operation (creates data reversibly). Severity is medium because incorrect observations could pollute the knowledge base and affect downstream reasoning, but the operation is not financially damaging or destructive.

From the tool's own definition: "Tool name 'create_observation' indicates a data creation operation. Grouped with other data manipulation tools like create_entity, create_relationship, delete_entity, and delete_relationship on the same server, suggesting it modifies stored state."

## Use case

AI agents use create_observation to create or update resources in Optimized Memory MCP Server V2, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Optimized Memory MCP Server V2 environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Optimized Memory MCP Server V2:

```json

      "limits": [
        {
          "counter": "create_observation_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`
