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

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

## Why create_chart is rated Medium

This tool creates a new chart object, which is a reversible write operation. It does not execute arbitrary code, delete data, or move money. However, 'flexible data input and configuration' suggests broad input acceptance, which could allow misuse to generate misleading or malicious visualizations if an agent misuses it without proper guardrails.

From the tool's own definition: "Tool named 'create_chart' with description 'Create a chart with flexible data input and configuration' performs creation of a new artifact (chart). The word 'Create' indicates data modification."

## Use case

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

## Recommended policy (PolicyLayer)
