# test_workflow_step

Run exactly ONE step of a workflow and return what it produced, so you can iterate on a single step's wording without running the steps before it. THIS SPENDS CREDITS EXACTLY LIKE A REAL STEP: the step runs on a real model through the same engine a full run uses and is billed identically -- it is not a simulation, a dry run, or a free preview. If you want to check a workflow's shape, parameters, models and cost estimate for free, use plan_workflow instead; that one runs nothing. Starts no session, so there is nothing to poll and nothing to advance. Requires authentication.

## Facts

- Tool: `test_workflow_step`
- Server: Meta Council (`https://meta-council.com/mcp`) — https://policylayer.com/tools/com-meta-council-decision-intelligence.md
- Homepage: https://github.com/daliu/meta-council
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server auth posture: open
- Server rate-limited: no
- Parameters: 4 (2 required)
- Recommended policy verdict: Allowed

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `query` | string | no | The input the step works on, exactly as you would pass it to run_workflow. Optional -- omit for a step whose instruction already carries everything it needs. |
| `workflow` | string | yes | The workflow slug (from list_workflows), e.g. 'due_diligence'. |
| `parameters` | object | no | Optional values for the workflow's declared parameters, as a flat name-to-value object, e.g. {"region": "EU"}. They are substituted into the step wording the sa |
| `step_index` | integer | yes | Which step to run, counting from 0. A workflow with 4 steps accepts 0 to 3; anything else is refused without spending. |

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": "test_workflow_step",
    "arguments": {
      "workflow": "<workflow>",
      "step_index": 0
    }
  }
}
```

## Why test_workflow_step is rated Low

Even though test_workflow_step only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

## Use case

AI agents call test_workflow_step to retrieve information from Meta Council 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 Meta Council:

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