THE RISK

Why create_workflow_run needs a policy

Starting a workflow run is an Execute-category action: it triggers an external process (Onfido identity verification workflow) whose effects depend on the arguments passed. This is not a simple read or write; it initiates a multi-step external operation. Severity is high because misuse could trigger fraudulent or unauthorized identity verification workflows, potentially with legal and compliance implications.

From the tool's definition 'Start an Onfido Studio workflow run' — triggers an external workflow execution in Onfido Studio

POLICY

How to control create_workflow_run

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_workflow_run": {
      "limits": [
        {
          "counter": "create_workflow_run_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

create_workflow_run stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Mcp Afip — 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 create_workflow_run

What does the create_workflow_run tool do? +

Start an Onfido Studio workflow run. Studio is Onfido. It is categorised as a Execute tool in the Mcp Afip MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on create_workflow_run? +

Register the Mcp Afip MCP server in PolicyLayer and add a rule for create_workflow_run: 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 Mcp Afip. Nothing to install.

What risk level is create_workflow_run? +

create_workflow_run is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit create_workflow_run? +

Yes. Add a rate_limit block to the create_workflow_run 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 create_workflow_run completely? +

Set action: deny in the PolicyLayer policy for create_workflow_run. 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 create_workflow_run? +

create_workflow_run is provided by the Mcp Afip MCP server (codespar/mcp-dev-latam). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Mcp Afip tool call.

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