# neuron_run_flow

Manually trigger a flow run for testing. Starts at the 'trigger.manual' node if present, otherwise the first trigger node. Optionally provide a payload object that becomes {{trigger.*}} in the flow.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | string | yes | UUID of the flow to run. |
| `nodeId` | string | no | Specific trigger node id to start from (for flows with multiple triggers). |
| `payload` | object | no | Test payload available as {{trigger.*}} in the flow — e.g. { text: 'hello', contactPhone: '2348012345678', senderName: 'Test User' }. |

Parameters from the server's own tool schema.

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

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

## Why neuron_run_flow is rated High

neuron_run_flow triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

Risk signals: Accepts raw HTML/template content (payload)

## Use case

AI agents invoke neuron_run_flow to trigger actions in Neuron. 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 Neuron:

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

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
