cfd_parametric_study · FreeCAD MCP: Risk & Policy

WHAT IT DOES

What cfd_parametric_study does on FreeCAD MCP

AI agents invoke cfd_parametric_study to trigger actions in FreeCAD MCP. 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.

WHY IT NEEDS A POLICY

Why cfd_parametric_study needs a policy

The tool name suggests running a parametric study in CFD (Computational Fluid Dynamics), which involves executing multiple simulation runs. Based on the server context (fluid simulation capabilities), this likely triggers external computation/simulation operations. However, the description is empty, so confidence is lowered.

From the tool's definition Tool name 'cfd_parametric_study' on a server that performs fluid simulation and structural analysis operations

Verdict

cfd_parametric_study Rate-limited

cfd_parametric_study 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches FreeCAD MCP, so you can run agents against it safely.

FAQ

Questions about cfd_parametric_study

What does the cfd_parametric_study tool do? +

cfd_parametric_study. It is categorised as a Execute tool in the FreeCAD MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on cfd_parametric_study? +

Register the FreeCAD MCP server in PolicyLayer and add a rule for cfd_parametric_study: 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 FreeCAD MCP. Nothing to install.

What risk level is cfd_parametric_study? +

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

Can I rate-limit cfd_parametric_study? +

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

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

cfd_parametric_study is provided by the FreeCAD MCP server (sandraschi/freecad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
