THE RISK

Medium Risk

Why test_workflow needs a policy

The tool initiates a workflow for writing or improving tests, which constitutes creating or modifying data (test files/code) in a reversible way. It does not execute code, delete data, or involve financial operations. Severity is medium because misuse could introduce incorrect or misleading tests into a codebase, but changes are reversible.

POLICY

How to control test_workflow

PolicyLayer is an MCP gateway — it sits between your AI agents and Structured Workflow MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for test_workflow:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "test_workflow": {
      "limits": [
        {
          "counter": "test_workflow_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

test_workflow stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Structured Workflow MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about test_workflow

What does the test_workflow tool do? +

Start a focused workflow for writing or improving test coverage. It is categorised as a Write tool in the Structured Workflow MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on test_workflow? +

Register the Structured Workflow MCP server in PolicyLayer and add a rule for test_workflow: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Structured Workflow MCP. Nothing to install.

What risk level is test_workflow? +

test_workflow is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit test_workflow? +

Yes. Add a rate_limit block to the test_workflow rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block test_workflow completely? +

Set action: deny in the PolicyLayer policy for test_workflow. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides test_workflow? +

test_workflow is provided by the Structured Workflow MCP server (kingdomseed/structured-workflow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Structured Workflow MCP tool call.

Start from Structured Workflow MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
