Why create_fluent_flow_system_live needs a policy

This tool executes an external operation against a running Workbench process, causing it to create a new Fluent simulation system. It spans Write and Execute; since it operates in a live engineering application environment via scripted automation with potentially complex side effects on the simulation environment, Execute is the more appropriate category.

From the tool's definition "Try to create a Fluid Flow (Fluent) system in the running Workbench bridge" — triggers creation of a simulation system in a live external application (Ansys Workbench) via a bridge/scripted journal

POLICY

How to control create_fluent_flow_system_live

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

policy.json

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

create_fluent_flow_system_live 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 Ansys Workbench — 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_fluent_flow_system_live

What does the create_fluent_flow_system_live tool do? +

Try to create a Fluid Flow (Fluent) system in the running Workbench bridge. It is categorised as a Execute tool in the Ansys Workbench 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_fluent_flow_system_live? +

Register the Ansys Workbench MCP server in PolicyLayer and add a rule for create_fluent_flow_system_live: 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 Ansys Workbench. Nothing to install.

What risk level is create_fluent_flow_system_live? +

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

Can I rate-limit create_fluent_flow_system_live? +

Yes. Add a rate_limit block to the create_fluent_flow_system_live 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_fluent_flow_system_live completely? +

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

create_fluent_flow_system_live is provided by the Ansys Workbench MCP server (hongwenwang36-eng/ansys-workbench-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Ansys Workbench tool call.

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