# simulate_transactions

Simulate one or more transaction groups built from decoded transaction objects, with a full SimulateRequest config (allowEmptySignatures, allowMoreLogging, allowUnnamedResources, execTraceConfig, extraOpcodeBudget, round). Use this when you need execution traces, extra opcode budget, to simulate unsigned txns, or to opt into Algorand v9+ simulate features. For a quick pass/fail check on pre-encoded bytes, use simulate_raw_transactions instead.

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

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

## Why simulate_transactions is rated High

This tool executes transaction simulations on the Algorand blockchain with full configuration control including opcode budget manipulation, unsigned transaction simulation, and execution traces.

From the tool's own definition: "Simulate one or more transaction groups built from decoded transaction objects, with a full SimulateRequest config (allowEmptySignatures, allowMoreLogging, allowUnnamedResources, execTraceConfig, extraOpcodeBudget, round)."

## Use case

AI agents invoke simulate_transactions to trigger actions in Algorand MCP. 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 Algorand MCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "simulate_transactions": {
      "limits": [
        {
          "counter": "simulate_transactions_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
