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

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

## Why set_entity_truecolor is rated Medium

This tool creates or modifies data (entity color attributes) in a reversible manner. It does not execute arbitrary code, delete data, move funds, or trigger irreversible changes. Misuse would result in unwanted color changes to CAD entities, which can be easily undone. This is classified as Write with low severity due to limited blast radius and fully reversible nature.

From the tool's own definition: "Tool name 'set_entity_truecolor' and description indicate it modifies entity color properties to RGB true color values."

## Use case

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