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

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

## Why getTransactionStateChanges is rated Low

This tool performs data retrieval only ('Retrieve'). It queries past transaction state changes on the Ethereum blockchain, which is a read-only operation with no side effects, no execution of arbitrary code, and no possibility of modifying or deleting data. The low severity reflects minimal blast radius if misused—an agent could at worst spam queries but cannot cause financial loss or data damage.

From the tool's own definition: "Tool name 'getTransactionStateChanges' and description 'Retrieve state changes that occurred during a transaction' both indicate a query operation that retrieves historical blockchain data without modifying or executing any actions."

## Use case

AI agents call getTransactionStateChanges to retrieve information from Agentek Eth without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Agentek Eth:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "getTransactionStateChanges": {}
  }
}
```
