Ansys Fluent / CFX AI: MCP servers and agent skills

Ansys publishes two official MCP servers on GitHub: PyFluent-MCP drives a live Fluent session and PyCFX-MCP drives CFX-Pre, the CFX solver and CFD-Post, both through the PyAnsys Python libraries. Community options add a broader Fluent/Mechanical server, a run-auditing Fluent server, a help-page navigator and a PyFluent scripting skill. Every live server needs a licensed local Fluent or CFX install, and the official pair are still 0.x releases that want Python 3.12 or newer.

  • Includes Ansys (Synopsys)'s official server (pre-1.0).
  • 6 MCP servers and 1 agent skill listed.

How AI connects to Ansys Fluent / CFX

An MCP server or skill can only do what Ansys Fluent / CFX lets programs do. Ansys Fluent / CFX exposes 3 automation interfaces:

  • PyFluent (ansys-fluent-core) (Python): PyFluent launches Fluent or attaches to a running session and talks to it over gRPC. It exposes the solver settings as a Python object tree, alongside the older text user interface (TUI) commands. The official PyFluent-MCP server builds directly on it, needs ansys-fluent-core 0.27 or later, and lets the agent browse that settings tree, look up allowed values and run checked Python in a persistent session. Documentation
  • PyCFX (ansys-cfx-core) (Python): PyCFX is the PyAnsys library for CFX. It starts or connects to CFX-Pre for setup, the CFX solver for runs and CFD-Post for results, which is the split the official PyCFX-MCP server mirrors with its single cfx_workflow routing tool and a bounded model-context tool that returns summaries instead of whole models. Documentation
  • Journal files and TUI batch runs (Command line): Fluent also runs unattended from a journal of TUI or Scheme commands, typically launched as fluent 3ddp -g -i journal.jou with a -t flag for the core count. Several community servers fall back to this route: one sends raw TUI commands to an open Fluent window, another keeps a journal backend next to PyFluent so each run leaves a reproducible log.

What Ansys (Synopsys) offers

Ansys added Engineering Copilot, an AI assistant for simulation setup and finding training material, to Fluent Desktop in 2025 R2, and offers AnsysGPT as a support assistant for commercial customers. Separately, the official ansys GitHub organisation publishes MCP servers for Fluent (PyFluent-MCP, 0.6.0) and CFX (PyCFX-MCP, 0.2.0) on a shared PyAnsys MCP base. The Fluent product-update page mentions no MCP or agent features for 2026 R1.

What you can do with Ansys Fluent / CFX and AI

  • Launch Fluent or attach to a running session, then inspect the live settings tree and allowed values before the agent changes a boundary condition or model.
  • Summarise a case setup, check mesh quality, compare two case files and write a simulation report with screenshots.
  • Set up, solve and post-process a CFX run across CFX-Pre, the CFX solver and CFD-Post from one conversation.
  • Run an existing case and data file in batch through a journal, keeping inputs, logs and a summary for each run, and review UDF source changes before they are compiled.
  • Look up the right page of the Fluent help for a turbulence model or solver setting without leaving the chat.

Installing

The listings here document setup for Claude Code, Claude Desktop, Cline, Codex, Cursor and VS Code (GitHub Copilot). Install steps, copied from each project's own documentation, are on each listing's page. Most Ansys Fluent / CFX integrations run on your own computer next to Ansys Fluent / CFX, so you need Ansys Fluent / CFX installed and licensed on the same machine unless the listing says otherwise.

Questions

Is there an official Ansys Fluent MCP server?

Yes. Ansys publishes PyFluent-MCP (pip package ansys-fluent-mcp) and PyCFX-MCP (ansys-cfx-mcp) in its own GitHub organisation, under Apache-2.0. Both were 0.x releases on 4 November 2026, so expect tool names and behaviour to change.

Can Claude run a Fluent simulation?

Yes, through an MCP server on a machine with a licensed Fluent install. PyFluent-MCP lists Claude Desktop among its clients and drives the solver through PyFluent over gRPC; tools that only read the API reference work without Fluent.

Does the official server run arbitrary Python inside Fluent?

Only through a checked path. PyFluent-MCP validates code and runs it behind an AST sandbox in a persistent session, and PyCFX-MCP restricts imports and built-ins. Ansys notes that the CFX sandbox is Python-level, not an operating-system or container sandbox.

What do I need installed?

Python 3.12 or later for both official servers, plus a licensed Fluent or CFX install for any tool that touches a solver. Ansys recommends stdio for desktop clients and HTTP only on trusted networks or behind authentication and TLS.

AI-generated models, drawings and results must be checked by a qualified engineer before use.
