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

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

## Why create_relationship is rated Medium

This tool creates new data (relationships) reversibly within an in-memory entity system. It is a Write operation—data can be added but is not irreversibly destroyed. Severity is medium because misuse could corrupt the logical structure of stored relationships, but the effect is confined to this server's memory store and can be corrected or cleared.

From the tool's own definition: "Tool name is 'create_relationship' and description states 'Create a relationship between entities.' The verb 'create' indicates data modification."

## Use case

AI agents use create_relationship 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.
