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

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

## Why create_entity is rated Medium

This tool creates new entities in the memory system, modifying the data store reversibly. It is a Write operation—data can be created and later modified or deleted. Severity is medium because uncontrolled entity creation could spam the memory system or create invalid references, but the effect is not destructive (reversible) and does not involve financial or code execution risk.

From the tool's own definition: "Tool name 'create_entity' and description 'Create a new entity' indicate data creation."

## Use case

AI agents use create_entity 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)

## 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`
