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

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

## Why diagram_create is rated High

The tool invokes an external service (Eraser.io) to generate diagrams, which constitutes triggering an external operation rather than a simple local write. The blast radius is medium since it interacts with a third-party platform but produces diagrams rather than moving money or deleting data.

From the tool's own definition: "'Create professional diagrams using Eraser.io' — triggers an external operation on a third-party service (Eraser.io)"

## Use case

AI agents invoke diagram_create to trigger actions in Templonix Lite MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

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