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

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

  "params": {
    "name": "createMemo",

## Why createMemo is rated Medium

This tool creates new memo records in a local LowDB database. Creation of new data is a Write operation. Severity is low because: (1) the operation is reversible (memos can be deleted), (2) the blast radius is limited to a local memo database with no external integrations or financial impact, and (3) misuse would only result in unwanted memo entries that can be cleaned up.

From the tool's own definition: "Tool name is 'createMemo' and description states 'Create a new memo'. The action creates new data in a local database without permanent destructive effects, modifications to existing records, or external side effects."

## Use case

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