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

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

## Why set_reward_recipient is rated Medium

This tool creates or modifies a reward recipient configuration, which is a Write operation (reversible state change). However, severity is high rather than medium because: (1) it operates within a financial system (Tempo blockchain stablecoin payments), (2) misconfiguration could redirect rewards to unintended addresses, and (3) it affects autonomous payment flows where an AI agent error could cause financial losses.

From the tool's own definition: "'Set or clear the auto-forward recipient for rewards' - modifies reward distribution configuration by setting or clearing a recipient address, which is a reversible change to payment routing logic."

## Use case

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